Bhubaneswar: In a major move to improve telecom security and user experience, Reliance Jio has officially launched the Caller Name Presentation (CNAP) service. This new feature aims to bring more transparency to every phone call you receive. 
When you receive a call from an unknown number, your phone screen will display the name registered on the caller's KYC (Know Your Customer) documents.

What is Jio CNAP?
The CNAP service is a caller identification feature that shows the real name of the person calling you. Unlike third-party apps like Truecaller, which rely on crowdsourced data and user-submitted contact lists, Jio’s CNAP uses official records.When you receive a call from an unknown number, your phone screen will display the name registered on the caller's KYC (Know Your Customer) documents. This means the name shown is the one verified by the telecom operator through Aadhaar or other official government IDs when the SIM card was purchased.
Why is this important?
The primary goal of this service is to curb the rising cases of spam and fraudulent calls. Many scammers use fake names or hide their identities to trick people. With CNAP, users can see the authentic name of the caller before they even pick up the phone.Key benefits include:
- Identity Verification: You know exactly who is calling based on legal records.
- Reduced Spam: It becomes harder for telemarketers and scammers to hide behind anonymous numbers.
- Enhanced Safety: Users can make informed decisions about whether to answer a call from an unfamiliar number.
How Does it Work?
The service works at the network level. When a call is initiated, the network identifies the registered name associated with the calling number and transmits it to the receiver's device.While the Telecom Regulatory Authority of India (TRAI) has been pushing for this feature across all networks, Reliance Jio is among the first to roll it out to its massive user base. The feature is designed to work seamlessly on supported smartphones without requiring the installation of any extra third-party applications.
Comparison: Jio CNAP vs. Third-Party Apps
| Feature | Jio CNAP | Third-Party Apps |
|---|---|---|
| Data Source | Official KYC / Government ID | User Contact Lists (Crowdsourced) |
| Accuracy | Very High (Verified) | Variable (Can be nicknames) |

- Odisha

- Haryana (Trial Phase)
- Telangana
How to Enable the Feature
The best part about Jio CNAP is its simplicity. Unlike other value-added services, you generally do not need to send an SMS or dial a code to turn it on.- Default Activation: For most users in the supported regions, the service is enabled by default at the network level. If you are using a compatible 4G or 5G smartphone, the KYC name should start appearing automatically for incoming calls from other Jio users.
- No App Required: You do not need to install the MyJio app or any third-party software for this to work. The name appears directly on your phone’s default calling screen.
- Check Your Settings: Ensure your phone's default "Caller ID and Spam" settings are turned on in your Phone app settings. This helps the system display the network-provided name correctly.
- Important Things to Note
- Inter-Operator Calls: Currently, the system works most accurately when a Jio user calls another Jio user. Full cross-network support (e.g., Airtel to Jio) is expected to become more consistent as other operators like Airtel and Vi complete their rollouts by early 2026.
- Privacy Control: If you do not want your KYC name to be displayed when you call others, the government is working on a procedure to allow users to "opt-out" or disable the service, though this is still being finalized.
- Feature Phones: Users with older 2G feature phones may not see this feature yet due to technical limitations of older network hardware.
As of December 2025, the Jio CNAP service is officially live in Odisha, including Bhubaneswar. Since you are in this region, you are likely already part of the initial rollout.

How to Check if it's Active
You can verify it through these steps:- Ask a Friend: Have someone with a Jio SIM who is not in your contact list call you.
- Observe the Screen: If the service is active, you will see a name appear on the calling screen instead of just the phone number.
- Check Call Logs: After the call, look at your recent call history. The verified KYC name will often appear next to the number, even if you haven't saved it.
If you are in Odisha but still only see numbers, check the following:
- Device Compatibility: Ensure you are using a 4G or 5G smartphone. Most modern Samsung, Google, and OnePlus phones support this natively.
- System Updates: Go to Settings > Software Update and ensure your phone is running the latest version. Manufacturers are currently pushing small "carrier setting updates" to enable CNAP support.
- Default Dialer: Ensure you are using the official "Phone" app that came with your device. Some third-party dialers may block the network-level name display.
