CNAP Caller Name Not Showing? How It Works on Jio, Airtel and Vi
From 1 November 2026, CNAP shows the caller’s registered name on 4G and newer networks in India. Here is how it works and what to check if no name appears.

CNAP caller name display is now switched on by default across India: from 1 November 2026, telecom operators must show the registered name of the person calling you on 4G and newer networks, even if the number is not in your contacts. You don’t need an app or any request to get it, but there are clear reasons why a name may not appear, and this guide explains each one and what to do about it.
Quick summary
- What: Calling Name Presentation (CNAP) shows the caller’s name with the number on incoming calls.
- Who ordered it: the Department of Telecommunications (DoT), through a circular dated 13 October 2026.
- From when: 1 November 2026, in all service areas.
- Networks: wireless 4G and higher. 2G, 3G and landlines will be considered separately.
- Name source: the caller’s name in their operator’s subscriber records, not a crowd-sourced app database.
- No name if: the number is saved in your contacts (your saved name shows), the call is international, or the caller uses CLIR.
How does CNAP caller name display work?
CNAP works inside the mobile network, not on your phone. When someone calls you, your operator looks up the caller’s name in a database kept by the caller’s operator and sends it to your phone with the number.
The DoT circular sets a fixed order for what you see in the name field:

| Type of incoming call | What the name field shows |
|---|---|
| Number saved in your contacts | The name you saved |
| Unsaved Indian number | The caller’s name from their operator’s records |
| International call | “International Call” |
| Caller has CLIR (identity restriction) | No name |
| Caller on 2G, 3G or landline | Not covered yet |
The circular also requires a “security by design” lookup, so the caller’s name is not kept after the call ends. Operators must still maintain the subscriber database itself.
Caller name not showing? Check these 6 things
If a call arrives with only a number, the reason is usually one of these. Work through them in order.
- Is the number saved? If it is in your contacts, your phone shows the name you saved, not the CNAP name. This is by design.
- Are you on 4G or 5G? The mandate covers 4G and higher networks. If your phone has dropped to 2G or 3G, or mobile data/VoLTE is switched off, the call may not carry a name.
- Is the caller on 4G or newer? Callers on 2G, 3G or a landline are outside the current rollout.
- Is it an international call? Calls from outside India show “International Call” instead of a name.
- Has the caller hidden their identity? Users with the CLIR facility do not have their name presented.
- Is your phone up to date? As a basic check, install the latest system and phone app updates, then restart the phone.
If none of these explains it, contact your operator’s customer care. The DoT has directed operators to receive, record and resolve CNAP complaints within a set time.
How to fix a wrong name shown for your number
The name people see when you call is the one recorded with your operator, so fixing it means correcting your subscriber details, not changing anything on your phone.
- Call someone whose phone does not have your number saved and ask what name appears.
- If it is wrong (for example, a family member’s name because the SIM is registered to them), contact your operator through customer care or a store.
- Ask how to update or transfer the subscriber details, and keep your identity documents ready for verification.
- If the issue is not fixed, raise a complaint with the operator and keep the reference number.
CNAP for business and bulk numbers
Businesses can show a brand name instead of the legal name on the connection, but only with proof. The circular allows a “preferred name” for business and bulk connections if it is either a trademark registered in the user’s name or a trade name registered on the GST portal.
- New connections: give the preferred name in the application form; the operator inspects original documents and keeps true copies.
- Existing connections: apply through the operator’s process; the name is updated only after verification.
For companies that call customers often, a verified brand name helps people recognise your calls. It works best alongside a consistent brand on your website and social media; our digital marketing checklist covers the basics.
CNAP vs caller ID apps: what’s different?
| Feature | CNAP | Caller ID apps |
|---|---|---|
| Name source | Operator’s subscriber records | The app’s own database |
| App needed | No | Yes |
| Internet needed | No, works over the network | Usually |
| Spam labels | No | Often |
| Coverage now | 4G and higher networks | Depends on the app |
A name on screen does not prove who is calling or why. Never share an OTP, PIN or bank details with an unknown caller, even if a name appears. For more on phone safety, see our guides to the Android SMS of Death bug and Jio’s voice-only plans under the TRAI rule.
Can you turn off CNAP?
The DoT circular makes CNAP a default service and does not describe a way for people receiving calls to switch it off. Callers who want to hide their identity can use CLIR where their operator offers it. For the latest options on your connection, check with your operator.
Frequently asked questions
Do I need to activate CNAP?
No. The DoT circular requires operators to provide CNAP to every user without a separate request from 1 November 2026, on 4G and higher networks.
Which operators show caller names?
The directive applies to all telecom service providers in every service area, which includes Jio, Airtel, Vi and BSNL on their 4G and newer networks.
Why does a different person’s name show for a number?
CNAP shows the name in the operator’s subscriber records. If a SIM is registered to someone else, such as a parent or employer, that person’s name appears.
Does CNAP block spam calls?
No. CNAP only shows a name; it does not block or label calls. Use your operator’s DND service or block the number to stop unwanted calls.
Bottom line
CNAP should put a real, operator-verified name on most unknown calls in India, with no app needed. If you don’t see a name, check whether the number is saved, whether both sides are on 4G or 5G, and whether the call is international or restricted; if your own name is wrong, the fix is with your operator.
