How to check which mobile numbers are issued in your name (Sanchar Saathi)

Why this matters

Every SIM issued against your ID is liability wearing your name: fraudsters routinely activate extra connections using leaked or misused KYC documents, then run scams, UPI fraud, and harassment campaigns from "your" number. In India, individuals are allowed a limited number of connections (nine, except J&K/Assam/North-East where it is six) — check yours before someone else uses the quota.

The check: TAFCOP on Sanchar Saathi (10 minutes)

The Department of Telecommunications runs this free at sancharsaathi.gov.in ("Know Your Mobile Connections" / TAFCOP):

1. Open the portal and choose the connection-listing service.
2. Enter a mobile number already in your name and verify it with the OTP.
3. The portal lists every connection issued against your ID — numbers you may never have seen.
4. Against any unfamiliar number, mark "Not my number" (or "Not required" for old ones you no longer use) and submit.
5. The operator must verify and disconnect flagged numbers; track the request ID until it closes.

Repeat yearly, and after any incident of document loss, SIM replacement, or SIM-swap suspicion.

Two sibling services on the same portal

• CEIR (lost/stolen phones): register your phone's IMEI (dial *#06# to see it, save it now) and block a stolen handset across all networks so it becomes a brick to resell.
• Chakshu (report fraud calls/SMS): report scam communications directly to DoT for enforcement action — faster than venting about them on social media.

Close the loop

• Unknown numbers in the list → flag on the portal, then score the callers with our phone-risk check.
• Any fraud already attempted → cybercrime.gov.in / 1930, and read India's threat landscape.
• Families: run this check for elders too — their IDs are the most misused, and they are the least likely to check unprompted.
