Scams & Fraud · URGENCY: HIGH
Fake KYC / Account-Update & SIM-Swap Fraud
A message or call warns your bank account, PAN, Aadhaar or SIM will be “blocked” unless you update KYC now — via a link, an app, or by sharing an OTP. It’s phishing (and sometimes SIM-swap). Never update KYC through a link or call; use only the official app or branch. If you shared details or your phone suddenly lost signal, contact your bank and telecom operator at once and call 1930.
The scam manufactures urgency — “your account will be suspended today” — to make you click a link, install an app or read out an OTP. In SIM-swap fraud, the goal is to port your number so the criminal receives your banking OTPs. Slowing down and using only official channels defeats both.
What to do now
- Do not click KYC/“update” links or install apps from such messages.
- Never share an OTP, PIN or full card/Aadhaar details with a caller.
- If you shared details, or your SIM suddenly stopped working, call your bank and telecom operator immediately, then 1930.
What to do now
- 01
Stop and don’t act on the message
Do not click the link, install the “KYC” app, or call the number in the message. Genuine KYC is never done through an SMS link or a pressure call.
- 02
Verify through official channels
Check your KYC status only via your bank’s official app/website or branch, or the official issuer (e.g., UIDAI for Aadhaar). Use contacts from your card or the official app — not the message.
- 03
If you already shared details
Tell your bank to block the card/UPI and watch for transactions; change internet-banking passwords; enable alerts.
- 04
Watch for SIM-swap
If your phone unexpectedly loses network for a while, contact your telecom operator — a criminal may be porting your number to capture OTPs.
- 05
Report it
Call 1930 if money moved, and report on cybercrime.gov.in with the message, number, link and any transaction details.

Frequently asked questions
My bank messaged that KYC will block my account today — is it real?
Treat it as a scam. Banks do not force urgent KYC through SMS links or pressure calls. Check only via your bank’s official app/branch, and never share an OTP.
My phone suddenly has no network — should I worry?
It can be a SIM-swap attempt to hijack your banking OTPs. Contact your telecom operator immediately, freeze banking access, and report on cybercrime.gov.in.
