Who Called Me From This Number? Safe Checks

Short answer: To find out who called you from an unknown number, search the number online, check whether it matches a company's official contact page, and use your phone's built-in caller ID or spam filter. Never give OTPs, PINs or remote access to a caller, and call back only on a number you have verified.

An unfamiliar number can be a delivery agent, a bank, a wrong number or a scammer. The aim is to identify the caller without giving anything away. This guide shows safe checks that need no special tools, the red flags that point to fraud, and where to report it in India. It does not include a number lookup tool, and PremiumAV does not collect any phone numbers for this guide.

Do not call back or reply blindly

Missed calls from unfamiliar numbers sometimes lure you into calling back. Calls from certain international prefixes can also carry high charges. Do not return a missed call from a number you cannot place, and do not reply to a text from it. Wait until you have done the checks below.

Search the number online

Type the full number into a search engine, with and without spaces or the country code. If it has been reported as a nuisance or scam, people often post about it on consumer forums. Also search the number together with the word "official". A business that really owns the number will usually list it on its own site.

No result is not proof of safety. New numbers are used constantly, and scammers spoof numbers that belong to real organisations.

Check the organisation's official website

If the caller claims to be from a bank, courier, telecom company or government office, open the organisation's official website yourself, or use the number printed on your card, bill or passbook. Compare it with the calling number. If they differ, treat the call as unverified. Remember that the number shown on your screen can be faked, so a match is helpful but not conclusive. The safest rule is to hang up and call the verified number yourself.

Ask them to identify themselves, then call back officially

Ask for the caller's name, department and the reason for the call. Do not give any personal details first. Then end the call and phone the organisation on its published number. A genuine caller will accept this. A scammer will pressure you to stay on the line, which is itself a warning sign.

Use your phone's built-in features

Most modern phones include caller identification and spam warnings in the Phone app's settings. You can also block numbers, send unknown callers to voicemail and silence calls from numbers not in your contacts. Using these features means you do not need to install an extra app that wants access to your contact list.

Red flags of scam calls

• KYC update or account blocked. A caller says your bank account, wallet or SIM will be blocked unless you update KYC now, then asks for an OTP, PIN or a link click.
• Parcel or courier problem. A package in your name "contains illegal items" and you must speak to an officer.
• "Digital arrest". Callers pretending to be police, customs or investigation officers say you are under arrest or surveillance on a video call and must transfer money to be cleared. No genuine agency arrests anyone over a video call or collects money to "verify" innocence.
• Electricity or gas cut-off. A message or call says your supply will be disconnected tonight unless you call a mobile number or install an app.
• Request for an OTP. A one-time password is the key to approving a payment or login. Nobody legitimate needs you to read it out.
• Remote access apps. A caller asks you to install an app so they can "fix" a refund or account problem. This gives them control of your screen and banking apps.
• Urgency and secrecy. You are told to act within minutes and to tell no one.
• Unexpected prize, job or refund that requires a fee first.

What to do if you already shared information

1. Stop the call and do not make any further payment.
2. Call your bank on its official number and ask it to block cards, UPI and net banking if needed.
3. Call 1930, the National Cyber Crime Helpline, quickly, and file a report on cybercrime.gov.in.
4. If you installed a remote-access app, uninstall it, disconnect from the internet and scan your PC. See our guide to checking for a virus.
5. Change passwords and PINs from a clean device and enable two-step verification.

Where to report suspicious calls in India

For serious fraud, use 1930 and cybercrime.gov.in. For suspected fraud communication by call, SMS or messaging app, the Department of Telecommunications runs the Sanchar Saathi portal, which has a "Chakshu" facility for reporting suspected fraud communications. For unwanted commercial calls and SMS, TRAI's Do Not Disturb service and its complaint helpline 1909 are the official routes. Official processes and app details change from time to time, so check the current steps on each government site.

Protect your PC too

Many phone scams continue on a computer, for example by sending a link to a fake payment page. Read our guides on checking whether a website is legit and social engineering attacks.

Frequently asked questions

How can I find out who called me from this number?

Search the number online, compare it with the organisation's official website, use your phone's built-in caller ID and spam filter, and ask the caller to identify themselves before you call back on a verified number.

Is it safe to call back an unknown number?

It is better not to. Verify the number first. If someone claims to be from a bank or courier, find their official number from your card, bill or website and call that instead.

What is a digital arrest scam?

It is a fraud in which callers pose as police or investigation officers and claim that you are under arrest or surveillance on a video call. They demand money to clear your name. Genuine agencies do not do this, so hang up and call 1930.

Why does a bank call ask me for an OTP?

A genuine bank never needs you to share your OTP, PIN or password with anyone. Anyone asking for an OTP is likely to be a scammer trying to approve a payment or log in as you.

Where can I report a fraud call in India?

Call the National Cyber Crime Helpline 1930 and file a report on cybercrime.gov.in. You can also report suspected fraud communications on the Sanchar Saathi portal and inform your bank right away if money is involved.
