Since 1 November 2026, more and more calls in India arrive with a name on the screen, even from numbers you've never saved. That's CNAP, the caller name display your mobile network now provides. So it's a fair question: if the network already tells you who's calling, why keep a caller ID app at all?
The short answer: CNAP tells you whose name a number is registered in. A caller ID app tries to tell you whether you want to pick up. Those are different jobs, and which one you need depends on the calls you get. We make BharatCaller, a caller ID app, so we're not neutral. We've tried to keep this even-handed, and we start with what CNAP does well.
What CNAP gives you, free
- The registered name. Your operator shows the name the caller's SIM is registered under, from its KYC records.
- Nothing to install. It's a network feature from Jio, Airtel, Vi or BSNL. In October 2026 the Department of Telecommunications told operators to switch it on by default for calls on 4G and newer networks.
- A flag for calls from abroad. International calls are shown as "International Call", which helps you spot a scammer pretending to be local.
- Business names. Businesses are expected to show a registered trademark or GST-registered trade name.
- Nothing to share. You don't upload your contacts or give any app permissions to see a CNAP name.
We explain how it works, and when it started, in our CNAP explainer.
What CNAP doesn't do
- It doesn't warn you about spam. A registered name says nothing about whether the same number has been calling strangers all week with loan offers.
- It doesn't block anything. Every call still rings.
- It may not be the name you know. A number can be registered to a parent, a spouse, an employer or a previous owner. Your plumber may show up under his brother's name.
- It has gaps. Calls on 2G and 3G and landlines are to be handled separately, people who restrict their caller ID (CLIR) are exempt and the rollout may not have reached every network and phone yet. If you see no name, our guide to why CNAP isn't showing a name covers the usual reasons.
- It doesn't help with messages. Many scams start with an SMS or a WhatsApp link, not a call.
What a caller ID app adds
- Spam warnings before you answer. Apps pool reports from their users, so a number many people have reported comes with a warning.
- Blocking on your phone. Block a number once and it stops ringing.
- The name people actually use. Most caller ID apps show names that their users have saved or suggested, so you may see "Raju Plumber" rather than a registered name you don't recognise.
- A second opinion. When CNAP shows nothing, an app may still have a name.
Truecaller makes much the same case on its own CNAP comparison page: CNAP shows a name from subscriber records, and an app adds community spam reports and blocking. That's true of most caller ID apps, ours included.
What an app asks of you
An app has trade-offs too:
- Data sharing. Caller ID apps work by pooling names and reports from their users. Read what an app shares and what it shows others.
- Permissions. It needs access to calls and usually contacts to work properly.
- Ads and upkeep. Most free apps show ads, and some phones stop background apps to save battery, which can switch caller ID off without telling you.
- It can be wrong too. Community names can be out of date, and a spam label can follow a number to its next owner.
CNAP vs a caller ID app, side by side
- Name shown: CNAP shows the registered KYC name. An app shows the name its users have saved, or a business name.
- Spam warning: CNAP has none. An app warns you when other users have reported the number.
- Blocking: CNAP can't block. An app can block numbers on your phone.
- Setup: CNAP needs none. An app needs installing, permissions and occasional checks.
- What you share: nothing extra for CNAP. For an app, it depends on the app, so read its privacy policy.
- Cost: CNAP is free. Most caller ID apps are free with ads, and some, such as Truecaller, also offer paid plans.
Who can manage with CNAP alone
If you get a spam call once in a while, mostly want to know which relative is calling from a new number and don't like the idea of sharing contacts with an app, CNAP plus the spam filter in your phone's dialler may be all you need. Switch on DND for promotional calls too: call or SMS 1909. Our guide to 140 and 1600 numbers explains what DND stops and what it doesn't.
Who still benefits from an app
- People who get loan, credit card or insurance calls every day from ordinary 10-digit numbers that DND can't recognise.
- Older parents, who answer every call and are the favourite target of fake bank and KYC callers. A warning before they pick up matters more than a name.
- Anyone whose phone or network doesn't show CNAP names yet.
- Small traders and freelancers who answer unknown numbers for work and want to know which ones others have reported.
They work together
You don't have to choose. CNAP shows its name on your phone's own call screen, and a caller ID app shows its own card alongside. If CNAP shows an ordinary person's name and the app says many people have reported the number as spam, take the warning seriously: a real name on a SIM doesn't mean the caller means well.
Where BharatCaller fits
BharatCaller is a free caller ID and spam-blocking app for Android, made in India by KickHead Softwares, a National Startup Awards 2020 winner, in Noida. Alongside CNAP, it gives you:
- Caller ID before you answer, using names from the BharatCaller community.
- Spam warnings before you answer, for numbers known for spam.
- Report and block: report a number as spam, and block any number you never want to hear from again.
Like other caller ID apps, it identifies callers from names people have saved in their contacts. Those names may be shown to other users as caller names, but never who saved them. Its privacy policy says personal information isn't transferred outside India. You can get BharatCaller on Google Play, and we compare it with the other options in our guide to Truecaller alternatives.
Quick answers
Is CNAP better than Truecaller?
They do different jobs. CNAP shows the registered name from your operator, free and with nothing to install. Truecaller and other caller ID apps add spam warnings and blocking, in return for sharing some data with the app.
Can I uninstall my caller ID app now that CNAP is here?
If you rarely get spam calls and CNAP names show on your phone, yes, you may not miss it. If you still get daily sales or scam calls, keep an app for the warnings and blocking.
Does CNAP work with caller ID apps?
Yes. CNAP comes from the network and shows on your phone's call screen whether or not you use an app.
Will CNAP stop spam calls?
No. It only adds a name. To cut promotional calls, register for DND on 1909, and report spam calls on 1909 or the TRAI DND app.
