You run a small tailoring shop. On Thursday evening you call a customer to say her blouse is ready. She doesn't recognise your number, she's had a long day and three loan agents have already called her. She taps Spam and moves on.
On Friday morning you call your next customer. Should her phone warn her that you're a spammer?
We don't think so. Since 5 November 2026, it doesn't.
One tap can follow you around
Reporting spam is how a community caller ID app learns. Every report helps the next person decide whether to answer. But a report is one person's opinion, made in a second, often in a bad mood and sometimes about the wrong number.
Think about who gets reported by mistake:
- Small businesses calling customers who forgot they gave their number.
- Delivery riders and drivers, whose calls come from numbers nobody saves.
- Doctors' clinics, schools and offices, calling about something you didn't expect.
- People in a quarrel. An ex, a landlord, a relative in a property dispute. A spam report is a very easy way to get even.
A label that says "spam" next to your name is hard to shake off. People stop answering. Your calls start to fail for reasons you can't see.
Why we changed the rule
Until November 2026, a single ordinary report could mark a number as possible spam for everyone, and people saying "not spam" afterwards didn't clear it. Most single reports were honest. But we couldn't tell the honest ones from the mistakes and the grudges, and the cost of being wrong fell on someone who had done nothing.
So on 5 November 2026 we changed it. One ordinary report is now yours alone. Nobody else sees a label, a warning or a count because of it. It takes reports from two different people before anyone else sees anything at all.
What we refused to do was throw single reports away. Your report is recorded straight away and counts towards the total. If you also blocked the number, it can't ring you again. It simply waits for a second, independent person before it says anything to the rest of the world.
How we built it
A few choices shaped the rule:
- People, not taps. What counts is how many different people reported a number. Reporting the same number ten times from one phone is still one person.
- No leaks. A lone report counts as zero everywhere a count could appear: on caller cards for other people and on the number's public page on our website. A count of "1" would tell the world, and often the caller, exactly who complained.
- Stronger labels need more people. Two reports are the start, not the finish. Calling a number confirmed spam takes many more independent reports, and blocking a number for everyone takes far more again. One person can never decide that on their own.
- Two signals are trusted from a single sighting. The first is a spam label from the caller's own mobile network, such as "Airtel Warning: SPAM". Operators' systems flag suspected spam by looking at calling patterns across their whole network, so one of their labels already rests on far more than one opinion. The second is a mark from a Spam Warrior, a reporter our team has vetted and trusts. Warriors have levels: a mark from our most trusted Warriors counts on its own, while newer Warriors' marks need others to agree. Neither signal blocks a number for everyone; each can only make it show as likely spam.
These rules run on our servers, so they decide what every copy of BharatCaller is told about a number, whichever version you use.
What reporting does today
After a call, BharatCaller's card shows four buttons: CALL, SAVE, BLOCK and SPAM. You'll find the same options on any number's page.
- SPAM opens "Mark [number] as Spam". Choose what kind of call it was (Sales, Donation, Scam or Others), whether it was a Business or an Individual, add a name if you know one, and tap Save.
- BLOCK does the same and also adds the number to your blocked list, so BharatCaller cuts its calls off on your phone. You can see and remove blocked numbers under Blocked Numbers in the side menu.
The type you pick matters. A number reported mostly as "Scam" is treated differently from one reported mostly as "Sales", and the categories only show once enough different people agree, so a single report never reveals what you said.
Report it officially too
A report in BharatCaller protects other BharatCaller users. It doesn't reach the telecom regulator or your operator. For that, use the free official routes:
- Unwanted sales calls and messages: complain by calling or sending an SMS to 1909, or through the TRAI DND app or your operator's app. Under TRAI's rules since 2025, complain within 7 days of the call. You don't need to have DND switched on to complain about an unregistered sender. Our guide to complaining to TRAI has the steps.
- Suspected fraud, where you haven't lost money: report it on Chakshu on Sanchar Saathi.
- If you've lost money: call 1930 at once and report it on cybercrime.gov.in.
TRAI itself has advised people to report spam rather than just block it, because blocking only hides a number on your own phone. Reports are what lead to action against the sender.
What it doesn't do
- A single report won't warn anyone else. That's the point, but it means a brand-new spam number may ring a few people before a second person reports it. Network labels and Spam Warriors help close that gap.
- It doesn't decide who's guilty. A spam label means enough people found the calls unwanted. It's not a legal finding about anyone.
- It isn't instant for the second report either. Labels are worked out on our servers and can take a little while to reach other phones.
How to report a number
- When the call ends, look at BharatCaller's card. If it's closed, open BharatCaller and tap the number.
- Tap SPAM, or BLOCK if you never want to hear from it again.
- Pick the type of call, choose Business or Individual, then tap Save.
- If it was a sales call or fraud, report it to 1909 or Chakshu as well.

Report every spammer you meet. Your report counts from the first tap. And if you ever find yourself on the other side, the tailor whose customer had a bad day, one tap won't follow you to your next call.
