Common questions

Spam Calls FAQ

Send SMS START 0 to 1909 to activate TRAI DND, which blocks all promotional calls including loan and financial product calls. Also install Truecaller or Whoscall to auto-identify and block callers not yet in the DND system. Together these two measures eliminate 95%+ of spam calls.
DND blocks registered telemarketers effectively. However, some spam calls originate from personal SIM cards or unregistered numbers — these bypass DND. Using Truecaller or Whoscall alongside DND gives the most complete protection. Report unregistered spammers to 1909 so TRAI can investigate and penalise them.
Yes. TRAI DND activation is completely free on all Indian networks — Jio, Airtel, Vi, and BSNL. Send START 0 to 1909 or call 1909 — there are no charges. The TRAI DND 3.0 app is also free on Google Play and App Store.
TRAI requires all legitimate telemarketers in India to make promotional calls from numbers starting with 140. If you receive a promotional call from a regular 10-digit number, that caller is an unregistered telemarketer — which is illegal. Report it to 1909. Truecaller Premium can block all 140-series numbers in one tap.
Send SMS to 1909 in this format within 3 days of receiving the call: COMP <spammer number> <dd/mm/yy>. Example: COMP 9876543210 14/04/26. You can also report directly in the TRAI DND 3.0 app by tapping any call in your log and hitting Report. TRAI can fine violators up to ₹1 lakh per complaint.
No. Automated robocalls for loan or financial offers are illegal in India under TRAI's TCCCPR 2018 regulations, especially to DND-registered users. A 2025 TRAI amendment specifically strengthened rules against auto-dialers and robocalls. If you receive one, report it — these callers face heavy fines and number disconnection.
Yes. Send START 1 to 1909 instead of START 0. This blocks only Category 1 — Banking, Insurance, Financial Products, and Credit Cards — while allowing other promotional categories. You can manage this more granularly in the TRAI DND 3.0 app.
