CNAP explained: what your customers will see when your business calls

CNAP (Calling Name Presentation) shows the caller’s name, from the operator’s KYC records, next to the number on an incoming call. On 13 October 2026 the Department of Telecommunications told every access provider to introduce it from 1 November 2026 on 4G and higher networks. For businesses that call customers back, the name on the screen is about to matter, and there is a way to choose it. This explainer is part of our glossary and rules series.

What exactly did DoT order?

DoT’s Circular 01/Licensing Policy/2026, dated 13 October 2026, refers to TRAI’s recommendations of 23 February 2024 and to trials operators ran on 4G and higher networks. It instructs all providers of access services to introduce CNAP across all service areas from 1 November 2026. The key conditions:

On by default. Operators must provide the service to each user without a separate request.
Two fields on screen. The number, as today, plus a name.
Order of names. First, the name saved in the receiver’s contacts. If the number is not saved: the calling name from the operator’s subscriber record for a domestic call, or the words “International Call”.
Operator databases. Each originating operator maintains the name database; the receiving operator fetches the name and presents it.
Privacy by design. The lookup must not retain the name after the call ends.
CLIR respected. Users with calling line identification restriction under DoT guidelines will not have their name shown.
Scope. 4G and higher wireless networks first. 2G, 3G and fixed-line (PSTN) networks “shall be considered separately”.

Before this circular, DoT had told Parliament on 5 August 2026 that CNAP was still in trials. The 1 November date is the first nationwide start instruction.

What will a customer see when your business calls?

Situation	Name shown
Customer has saved your number	Whatever they saved it as (“Dr Rao Clinic”, “Sharma ji workshop”)
Not saved; you call from a business connection with a verified preferred name	Your preferred name (registered trademark or GST trade name)
Not saved; business connection without a preferred name	The name in the operator’s subscriber record, often the legal entity name
Not saved; staff member’s personal SIM	That person’s KYC name, not your business
Caller has CLIR	No name
Customer on 2G/3G, or the call is from a landline	Not covered by the 1 November start; likely number only

The last two rows matter more than they look. Reporting by ETTelecom notes that CNAP has so far worked only on smartphones and not on feature phones on legacy 2G networks.

How does the “preferred name” work for businesses?

Paragraph 6 of the circular lets operators offer users who hold business or bulk connections a preferred name in place of the name in the subscriber record, on these conditions:

The name must be either a trademark registered in your name with the Trade Marks Registry, or your trade name as registered on the GST portal.
The operator verifies it before use, against original documents, and keeps a copy.
For new connections, the name is recorded in the customer application form and subscriber record.
For existing connections, operators must set up a way to apply and get it updated after verification.

DoT’s earlier KYC instruction of 21 November 2025 also says an operator that assigns a preferred name without proper verification is responsible for misuse, and that inspections of business premises will check the name belongs to the entity.

What should a business do before 1 November?

List the numbers you call customers from. Office mobiles, staff SIMs, landlines, cloud telephony. Calls from staff personal SIMs will show the staff member’s name.
Check whose name each connection is in. Ask your operator what is in the subscriber record for each business connection.
Apply for a preferred name if your customers know you by a brand or trade name rather than your legal entity name. Keep your GST certificate or trademark registration ready.
Ask your cloud telephony or SIP provider how CNAP will apply to your numbers, since fixed-line networks are not part of the first phase.
Keep names consistent. The same name on your calls, your WhatsApp Business display name and your Google Business Profile helps people recognise you.
Still say your name first. Saved contacts override CNAP, many phones are not covered yet, and people are far more likely to stay on a call that opens with who is calling and why.

What does CNAP change for AI receptionists and callbacks?

A missed-call callback is only useful if the customer picks up. Today many callbacks from an unknown number are ignored. Once your business name appears, a callback within minutes of a missed call is more likely to be recognised. That makes two things worth doing:

Call back from a business connection that carries your verified name, not a random number.
Open every callback with the business name and the reason (“Namaste, Sharma Dental se bol rahe hain, aapka call miss ho gaya tha”). Ready-made lines are in our call scripts.

CNAP does not change the rules on who you may call: promotional calls still need consent and the 140 series, and regulated financial entities use 1600 numbers for service calls. See DLT and the 1600 series. The full missed-call flow is in missed-call recovery with Voice + WhatsApp, and the missed-call revenue calculator shows what recovered calls could be worth with your own numbers.

How Vocora handles caller identity

Vocora Voice AI answers on the number you already publish and, where you choose, calls back from your business line with your name in the first sentence. Confirmations go out on WhatsApp from your verified business profile, so the name customers see is the same on both channels.

If customers already see your number flagged, read why a business number shows as spam and how to fix it; a verified name helps, but operators score calling behaviour too.

FAQ

What is CNAP?

Calling Name Presentation: a network service that shows the caller’s name, taken from the operator’s KYC records, next to the number on an incoming call. TRAI recommended it on 23 February 2024 and DoT has instructed operators to introduce it from 1 November 2026.

When does CNAP start in India?

DoT’s circular of 13 October 2026 tells all access service providers to introduce CNAP across all service areas from 1 November 2026 on 4G and higher wireless networks. 2G, 3G and fixed-line networks will be considered separately.

Which name will show when my business calls a customer?

If the customer has saved your number, their saved contact name shows. If not, the name in your operator’s subscriber record shows, which for a business connection can be a verified preferred name. International calls show “International Call”.

Can my business show its brand name instead of the company name?

Business and bulk connections can ask their operator to show a preferred name. DoT’s circular says it must be a trademark registered in your name or your trade name on the GST portal, verified by the operator against original documents.

CNAP kya hai?

CNAP ka matlab hai Calling Name Presentation. Isme incoming call par number ke saath caller ka naam dikhega, jo telecom operator ke KYC record se aata hai. DoT ne operators ko 1 November 2026 se 4G aur usse upar ke networks par ise shuru karne ko kaha hai.

Is CNAP the same as Truecaller?

No. Apps like Truecaller rely on crowdsourced names. CNAP is delivered by the telecom network using the operator’s verified subscriber data, and DoT’s circular requires operators not to retain the name after the call is completed.

Can I hide my name?

Users who have Calling Line Identification Restriction (CLIR) under DoT guidelines will not have their name presented. For a business making service calls, hiding identity usually makes callbacks less likely to be answered.
