Getting your Trinity Audio player ready...

India is preparing to launch a revolutionary caller identification system that could transform how millions of people handle incoming calls. The Calling Name Presentation (CNAP) feature, expected to roll out nationwide by March 31, 2026, represents the government’s most ambitious move yet to combat the epidemic of spam calls, fraud, and digital crimes that plague Indian mobile users daily. Unlike popular third-party applications like Truecaller, CNAP will be a government-backed, network-level solution that displays verified caller names based on official KYC (Know Your Customer) documents.

What Is CNAP and How Does It Work?

CNAP is a supplementary telecom service that displays the caller’s verified name alongside their phone number during incoming calls. The system operates directly within India’s telecommunications infrastructure, making it fundamentally different from app-based solutions

The Technical Foundation

When someone makes a call, the recipient’s telecom operator queries the Local Number Portability Database (LNPD) to identify the originating service provider. The system then retrieves the caller’s registered name from the originating operator’s Calling Name (CNAM) database, which contains subscriber information sourced directly from KYC documents submitted during SIM card registration. This verified name appears on the recipient’s screen before the phone even starts ringing.

The Telecom Regulatory Authority of India (TRAI) has proposed four different implementation models:

Operator-Based CNAP Database: Each telecom service provider maintains its own CNAM database of subscribers. When a call is made, the caller’s operator extracts the verified name and transmits it to the recipient’s operator for display.

Shared Database Between Operators: Calling operators share their CNAM databases with receiving operators, allowing direct access to caller information.

Centralized Third-Party Database: A centralized repository operated by a third party stores all caller data, with operators retrieving information from this central source.

Synchronized Databases: Each operator maintains its own database while also retaining a copy of a synchronized central database for internal lookup.

CNAP vs Truecaller: Understanding the Key Differences

While both CNAP and Truecaller aim to identify incoming callers, the differences between them are significant and could determine which service users ultimately prefer.

Data Source and Accuracy

The most fundamental difference lies in how each service obtains caller information. Truecaller relies predominantly on crowdsourced data collected from users’ contact lists and community reports. When you install Truecaller, the app requests access to your entire phone contact list and uploads this information to its servers. This means that even people who have never used Truecaller may have their information in its database simply because someone else saved their contact details.

This crowdsourcing approach creates significant accuracy issues. Since users can name contacts however they wish in their phonebooks, Truecaller’s database often contains incorrect, outdated, or even offensive labels. For example, if someone saves a number as “spam caller” or something worse, that label gets uploaded to Truecaller’s global database.

In contrast, CNAP pulls caller names directly from official government-verified KYC documents used for SIM card registration. This authentication through telecom operators ensures considerably higher accuracy and reliability. The name displayed through CNAP is exactly as it appears in the subscriber’s official identity documents, not a crowdsourced label that could be incorrect or malicious.

Privacy and Data Collection

Truecaller has faced intense scrutiny over its data collection practices. The app collects far more than just phone numbers and names—it accesses contact lists, call logs, SMS metadata, search queries, websites visited, and even device location information. Most concerning is that Truecaller collects data about people who never consented to use the service, simply because their friends or contacts have the app installed.

Research by Viceroy revealed that Truecaller’s data collection practices may violate both Google’s privacy policies and EU/UK GDPR regulations. The company has been accused of collecting people’s data without explicit consent, and privacy experts note that Truecaller operates differently in India than in Europe, where stricter data protection laws apply.

CNAP, being a network-level feature built into telecom infrastructure, does not require downloading additional apps or granting extensive permissions. The service will be enabled by default for all users, though subscribers can opt out by contacting their telecom provider. Users who have enabled Calling Line Identification Restriction (CLIR)—a feature typically available to VIPs and high-ranking officials—will remain exempt from the system.

Cost and Accessibility

Truecaller offers both free and premium subscription tiers. While basic caller identification is free, advanced features like auto-blocking spam calls, fraud detection, and an ad-free experience require a paid Premium subscription. As of May 2025, Truecaller reported over 3 million paying subscribers globally.

CNAP, as a native telecom service, will be provided at no additional cost to subscribers. Being integrated directly into network infrastructure, it eliminates the need for separate app downloads, internet connectivity, or premium subscriptions. This makes CNAP accessible to a much broader user base, including those with limited smartphone capabilities or data plans.

Network Compatibility and Device Requirements

CNAP will initially be available only on 4G and 5G networks due to technical limitations. The feature requires IP-based networks and cannot function on older circuit-switched 2G and 3G networks without substantial infrastructure upgrades. This means approximately 200 million Indian users still on 2G networks will not have access to CNAP initially.

Truecaller, being an app-based solution, works across all network types as long as users have a smartphone with internet connectivity. However, CNAP has a distinct advantage—it will work on both smartphones and basic feature phones that support 4G/5G, as long as the device firmware is compatible.

Why CNAP Matters: The Spam and Fraud Crisis in India

India faces an unprecedented crisis of spam calls, fraudulent communications, and sophisticated scams that cost victims billions of rupees annually. Understanding the scale of this problem helps explain why CNAP is worth waiting for.

The Scale of India’s Spam Problem

According to Truecaller’s own research, India ranked fourth globally for spam calls in 2021, with users receiving an average of 16.8 spam calls per month. More alarmingly, over 202 million spam calls were made by just one spammer in India in a single year—that’s over 664,000 calls every day and 27,000 calls every hour from a single phone number.

A recent study published in India Today revealed that more than 60 percent of Indians receive three or four spam calls daily. The vast majority—93.5 percent—of spam in India consists of sales or telemarketing calls, often originating from telecom operators themselves.

The Digital Arrest Scam Epidemic

Beyond simple spam, India is grappling with a terrifying new form of cybercrime called “digital arrest”. In these elaborate scams, fraudsters impersonate law enforcement officers, judges, or government officials through audio or video calls. They accuse victims of serious crimes like money laundering or drug trafficking, then conduct fake court proceedings and police interrogations over video calls.

Victims are told they are under “digital arrest” and must not leave their room, turn off their camera, or contact anyone else while the “investigation” proceeds. Under extreme psychological pressure, victims are coerced into transferring large sums of money as “bail” or “verification fees”.

The statistics are devastating. According to government estimates, Indians lost more than ₹19 billion (approximately $350 million) to approximately 120,000 such scams in 2024 alone. The number of reported digital arrest fraud instances nearly tripled between 2022 and 2024. In one heartbreaking case, an 83-year-old retired government official in Pune died of a heart attack just a month after being defrauded of ₹1.2 crore in a digital arrest scam.

How CNAP Addresses These Threats

CNAP is specifically designed to combat these fraud schemes by providing verified caller identification. When implemented, users will see the actual registered name of anyone calling them, making it much harder for scammers to impersonate government officials or law enforcement.

The system’s reliance on official KYC records ensures accountability. Unlike Truecaller, where scammers can potentially manipulate crowdsourced data, CNAP’s government-verified information provides an authentic paper trail. If someone receives a call claiming to be from the CBI or police, they can immediately verify whether the caller’s displayed name matches legitimate government credentials.

Furthermore, CNAP will help users identify legitimate callers they might otherwise ignore. Currently, many genuine calls go unanswered because recipients cannot identify unfamiliar numbers. With verified name display, users can make informed decisions about which calls to answer, reducing both missed important calls and susceptibility to fraud.

Current Status: Pilot Programs and Rollout Timeline

The journey toward nationwide CNAP implementation is already underway, with several telecom operators conducting pilot tests to ensure system readiness.

Pilot Programs in Progress

Vodafone Idea launched CNAP pilot testing in Haryana in October 2025. Reliance Jio is also conducting pilots in Haryana for calls originating from anywhere in India. These early-stage pilots are designed to test network readiness, interoperability between operators, and user response before full deployment.

The trials have focused on inter-operator compatibility, ensuring that calls from one network correctly display caller identification on another network. Both Airtel and Vodafone Idea have partnered with Nokia to deploy the IP Multimedia Subsystem (IMS) platform nationwide—core technology that enables CNAP functionality. Jio has built its CNAP solution in-house and, being a pure 4G/5G operator, is reportedly better positioned for early adoption.

March 2026 Target Date

The Department of Telecommunications (DoT) has set an ambitious target for pan-India CNAP rollout by March 31, 2026. While the government initially had an internal target for the end of 2025, officials communicated to telecom operators that the service should be available across all circles by March 2026.

DoT sources indicate they are not waiting for a perfect version. “If the service works reliably in 80–90% of cases, we’ll move ahead with wider implementation,” one official stated. This pragmatic approach suggests that the March 2026 timeline is achievable, even if some technical challenges remain.

Regulatory Framework

The regulatory framework supporting CNAP has evolved significantly. Initially, TRAI recommended in February 2024 that CNAP should be activated only upon subscriber request—an opt-in model. However, DoT proposed that the feature should be enabled by default for all subscribers, with an option to opt out if users prefer not to use it.

TRAI has since “noted” DoT’s view without countering it, effectively clearing the path for default implementation. This means once CNAP launches, all compatible users will automatically see verified caller names unless they specifically choose to disable the feature.

Telecom license conditions will be amended to ensure all new devices sold in India after a notified cut-off date support CNAP, in coordination with the Ministry of Electronics and Information Technology (MeitY).

Implementation Challenges and Concerns

While CNAP promises significant benefits, several technical, financial, and privacy concerns have been raised by industry stakeholders and privacy advocates.

Technical Limitations

The most significant technical challenge is that CNAP cannot function on 2G and 3G circuit-switched networks. As one industry executive explained, “CNAP is generally an LTE feature and there are no standards for its implementation over 2G and 3G networks”. Implementing CNAP on these older networks would require expensive software patches and infrastructure upgrades that may not be economically viable given the low revenue generation from 2G users.

This limitation means approximately 200-300 million 2G users will not be able to access CNAP initially. Even for 4G and 5G networks, implementing CNAP is expected to increase call setup times, potentially affecting call quality and user experience.

Cost Concerns

Telecom operators have raised concerns about the substantial investment required for network upgrades and database management. The industry has already invested heavily in Distribution Ledger Technology (DLT) to reduce spam calls and messages under TRAI’s mandate, and operators argue they should not be burdled with additional costs for CNAP to address similar problems.

The Cellular Operators Association of India (COAI) pointed out that a detailed cost-benefit analysis should be conducted before mandating CNAP implementation. Given that the industry is transitioning to 5G, the additional cost of implementing CNAP “would not benefit the players,” according to industry submissions.

Privacy and Autonomy Concerns

While CNAP aims to enhance security, privacy advocates have raised important concerns about mandatory disclosure of KYC-verified names with every call. Telecom consultant Mahesh Uppal warns, “There are legitimate reasons why a person may not wish to reveal his/her identity to the called party. Examples include whistleblowers, those reporting abuse, and medical professionals”.

Privacy experts argue that CNAP should offer granular opt-in controls rather than default exposure. Currently, the proposed system does not provide users meaningful choice about when and to whom their verified identity is disclosed. As one legal commentary noted, “Depriving consumers of the choice to opt in for such a solution that could potentially cause them harm, as it entails disclosure of KYC-verified information, poses far-reaching consequences for the digital economy”.

Data Accuracy Issues

The assumption that the SIM owner and the actual caller are always the same person is problematic in Indian context. Mobile connections are often registered under a family member’s or employer’s name, with rules allowing up to nine SIM cards to be registered on a single ID. For shared connections, family-owned devices, or corporate phones, CNAP may display incorrect caller information, potentially causing confusion or mistrust.

Truecaller’s Response and Market Position

Despite concerns that CNAP could disrupt its business model, Truecaller has taken a surprisingly measured stance on the government’s initiative.

Truecaller’s Official Position

When TRAI first recommended CNAP in February 2024, Truecaller issued a statement welcoming the proposal, saying it would “not be competitive” to its suite of services. The company extended support to the recognition of Caller ID as an important building block of the information communication economy, stating that number identification will help end the menace of spam and scam calls.

Truecaller’s confidence stems from the breadth of its service offerings beyond basic caller identification. The app provides spam blocking, fraud SMS detection, call recording, messaging features, and even financial services through Truecaller Pay. With over 450 million monthly active users globally as of April 2025—including approximately 272-300 million in India—Truecaller has built a massive ecosystem that extends far beyond simple caller ID.

Truecaller’s Competitive Advantages

Truecaller offers several features that CNAP cannot replicate. The app’s spam blocking functionality automatically identifies and blocks known spam numbers in real-time, updating spam lists daily. Premium users can enable “Auto-Block Spam” which automatically declines fraudulent calls before the phone even rings.

The SMS Fraud Detection feature protects users from deceptive text messages by displaying red notifications for fraudulent messages and automatically disabling suspicious links. Truecaller also provides AI-powered assistants, call recording, and a comprehensive business platform for verified business identities.

Perhaps most importantly, Truecaller works across all network types and in countries worldwide, whereas CNAP is limited to India’s 4G/5G infrastructure. For users who frequently travel internationally or still use older network technologies, Truecaller remains the more versatile option.

Market Growth Despite CNAP

Truecaller continues to demonstrate strong growth despite the impending CNAP launch. The company surpassed 450 million monthly active users in April 2025, adding approximately 50 million users over 10 months. Paid subscriptions have grown particularly rapidly, with Truecaller surpassing 3 million paying subscribers in May 2025, including 1 million on iOS alone.

India remains Truecaller’s largest market, accounting for 74.2 percent of the company’s sales revenue. The company’s strategy focuses on transforming from a basic caller ID utility into a premium communication platform with AI-led features, advanced spam blocking, and fraud insurance for premium users.

Why CNAP Is Worth Waiting For

Despite implementation challenges and the continued presence of alternatives like Truecaller, CNAP represents a significant leap forward in telecommunications security and user protection. Here’s why this government-backed initiative is worth the wait.

Verified Authenticity at Scale

CNAP’s greatest strength is its foundation on verified, government-authenticated data. Unlike crowdsourced databases that can contain errors, outdated information, or malicious labels, CNAP displays the exact name from official KYC documents. This authenticity is crucial for combating sophisticated fraud schemes where impersonation is the primary attack vector.

For a country where digital arrest scams have tripled in recent years and cost victims billions of rupees, verified caller identification could be life-saving. When fraudsters impersonate law enforcement officials, victims will be able to cross-reference the displayed CNAP name against legitimate government directories, making such scams much harder to execute.

Universal Access Without Apps or Internet

CNAP’s network-level implementation means it will work automatically for all compatible devices without requiring app downloads, account creation, or active internet connections. This democratizes access to caller identification for millions of Indians who may not have smartphones capable of running Truecaller, limited data plans, or the technical knowledge to install and configure third-party apps.

The service will be free and enabled by default, ensuring that even economically disadvantaged users, rural populations, and elderly individuals can benefit from caller verification. This universal accessibility aligns with India’s digital inclusion goals and helps protect vulnerable populations most susceptible to fraud.

Privacy by Design

While privacy concerns exist around mandatory name disclosure, CNAP actually offers better privacy protections than Truecaller in several important ways. First, CNAP does not collect or store users’ contact lists, call logs, SMS content, location data, or browsing habits. The system simply displays information already registered with telecom operators during the mandatory KYC process.

Second, users maintain control through opt-out provisions. If someone prefers not to have their name displayed when calling others, they can request this by contacting their telecom provider. This is fundamentally different from Truecaller, where opting out is complex and your information may still appear in the database because others uploaded your contact details.

Strengthening Digital Trust

CNAP represents a major step toward building a safer digital communication ecosystem in India. By integrating verified caller identification directly into telecommunications infrastructure, the government is establishing accountability and transparency as default features of mobile communication.

This government backing sends a strong signal that consumer protection and cybercrime prevention are national priorities. As India continues its digital transformation, establishing trust in basic communication channels becomes foundational to broader digital initiatives in healthcare, finance, education, and governance.

Complementary to Existing Solutions

Importantly, CNAP does not preclude users from continuing to use Truecaller or other caller identification apps. Users who value Truecaller’s additional features—spam blocking, SMS fraud detection, call recording, business verification—can use both services simultaneously. CNAP provides a baseline of verified identification, while apps like Truecaller add enhanced functionality and crowdsourced intelligence.

This complementary relationship means users get the best of both worlds: government-verified authenticity from CNAP and community-powered spam intelligence from Truecaller. As Truecaller itself acknowledged, CNAP recognition of caller ID’s importance validates the problem space while not directly competing with its comprehensive service suite.

What Users Should Know Before the 2026 Launch

As the March 2026 rollout approaches, there are several practical considerations users should understand to prepare for CNAP implementation.

Device Compatibility Requirements

CNAP will initially work only on devices that support 4G or 5G networks. If you are currently using a 2G or 3G connection, you will need to upgrade to a 4G-enabled device and plan to access CNAP features. New smartphones coming to market after the official notification date will be required to support CNAP functionality.

Feature phones with 4G capability may also support CNAP, depending on manufacturer implementation and firmware updates. Contact your device manufacturer to confirm whether your specific model will receive CNAP support.

Network Provider Preparation

All major Indian telecom operators—Reliance Jio, Bharti Airtel, and Vodafone Idea—are preparing for CNAP deployment. Jio, being a pure 4G/5G network, is best positioned for early implementation. Airtel and Vodafone Idea users may experience staggered rollouts as these operators complete network upgrades and Nokia IMS platform integration.

If you are on a smaller regional telecom provider or BSNL (which has indicated infrastructure limitations), you may experience delayed CNAP availability or limited functionality. Check with your service provider for specific rollout timelines in your area.

Managing Privacy Preferences

CNAP will be enabled by default, meaning your KYC-registered name will automatically display when you call others. If you prefer not to share your name, you will need to proactively contact your telecom provider to request opt-out. Be prepared to provide identification and possibly complete additional forms to exercise this option.

Remember that opting out means other people will not see your verified name when you call them, but you will still see caller names from others who have not opted out. Consider whether the privacy benefit outweighs the trust and authentication advantages of name display.

Verifying Caller Identity

Once CNAP launches, use it as one tool in a comprehensive approach to call verification—not as the sole indicator of legitimacy. Remember these important principles:

No government agency conducts digital arrests. If someone claiming to be law enforcement keeps you on video call and threatens arrest, it is a scam regardless of what name appears on your screen.

Verify through official channels: If you receive a call claiming to be from a bank, government agency, or company, hang up and call back using the official number from their website—never use contact information provided by the caller.

Be wary of pressure tactics: Legitimate organizations do not demand immediate money transfers or threaten consequences for not acting instantly.

Report suspicious calls: If you receive fraudulent calls, report them immediately via the cyber helpline 1930 or through cybercrime.gov.in and sancharsaathi.gov.in.

Understanding Limitations

CNAP will display the name registered with the SIM card, which may not always be the person actually using the phone. Corporate phones, family-shared connections, or SIM cards registered under someone else’s name will display the registered owner, not the current user. Keep this limitation in mind when making identity assumptions based solely on CNAP information.

For international calls or calls from numbers not registered with Indian telecom operators, CNAP will not display verified names. In these cases, you will see only the phone number as you do currently.

External Resources for Further Information

To stay updated on CNAP implementation and learn more about protecting yourself from spam and fraud, these external resources provide valuable information:

• TRAI Official Website: The Telecom Regulatory Authority of India publishes official recommendations, consultation papers, and regulatory updates on CNAP implementation.
• Department of Telecommunications: DoT provides guidelines on subscriber verification, telecommunications policy, and official announcements regarding CNAP rollout timelines.
• Cybercrime Reporting Portal: Government of India’s official portal for reporting cybercrimes, including digital arrest scams, spam calls, and fraudulent communications.
• Sanchar Saathi Portal: DoT’s citizen-centric platform for telecom services, including tools to track mobile connections registered under your name and report fraudulent activities.
• National Cyber Crime Helpline (1930): 24/7 helpline for immediate reporting of cybercrimes and receiving guidance on handling suspicious communications.

India’s Calling Name Presentation (CNAP) represents a landmark initiative in the fight against spam calls, fraud, and cybercrime. By providing government-verified caller identification directly through telecom network infrastructure, CNAP addresses fundamental weaknesses in current caller identification systems and offers protections that third-party apps alone cannot provide.

While CNAP faces implementation challenges—including technical limitations on older networks, cost concerns for operators, and privacy considerations—the March 2026 rollout timeline appears achievable based on current pilot programs. The system’s foundation on official KYC data ensures accuracy and authenticity that crowdsourced databases cannot match.

Truecaller and similar apps will continue to play important roles in the caller identification ecosystem, offering advanced features, spam intelligence, and cross-network compatibility that complement CNAP’s baseline verified identification. Rather than competing directly, these solutions can work together to provide Indian users with comprehensive protection against unwanted and fraudulent communications.

For the millions of Indians who receive spam calls daily and the thousands who have fallen victim to digital arrest scams, CNAP cannot come soon enough. The combination of verified authentication, universal accessibility, and government backing makes this 2026 anti-spam update genuinely worth waiting for—a significant step toward safer, more trustworthy digital communication in India.
