Source review: 18 October 2026. This guide reviews documentation and claims; it is not a hands-on app test.
To check mobile numbers registered in your name in India, use Sanchar Saathi’s “Know Mobile Connections in Your Name” service, commonly called TAFCOP. It is a Department of Telecommunications service for reviewing your own connections and reporting unfamiliar or unneeded ones. It is not a public lookup tool for investigating another person’s identity.
Start from the official government portal and authenticate using your own mobile number. Review the results carefully before reporting anything. A connection used by a family member may still have been issued in your name, so an unfamiliar-looking entry needs checking rather than an automatic complaint.

What to have ready
The National Government Services Portal’s service description specifies a mobile number, captcha and OTP. Keep the phone that receives the message available. Do not ask someone to send you their OTP or put your code in a public comment.
The basic login description does not require typing an Aadhaar number. The earlier statement that you cannot use the service without an Aadhaar card was too restrictive. If an operator later requires re-verification, follow its official instructions for accepted identity documents; that is a separate process from opening the portal.
Prepare a private list of your current SIMs and any connections you obtained for family use. This makes it easier to recognise entries. Do not upload identity documents to an unofficial “SIM checker” page or pay an intermediary simply because a search advertisement offers to do the check for you.
How to check your connections
- Open the official Sanchar Saathi portal.
- Choose the service for knowing mobile connections issued in your name.
- Enter your own mobile number and complete the captcha shown.
- Request the OTP and enter it only on the official service page.
- Review the connections returned and compare them with your records.
- Read the available report choices before submitting any request.
Labels and page layout can change. This review confirmed the process through government documentation; we did not log in with a subscriber’s number or inspect a private connection list. The service endpoint could not be fetched by our research tool, so this is not a claim of a completed live account test.
Report the right connection for the right reason
The government’s Sanchar Saathi explanation describes reporting fraudulent and unrequired connections and triggering re-verification. That process involves the telecom provider. Do not interpret submission as proof that a connection has already been disconnected.
| What you find | What to do |
|---|---|
| A number you recognise and still need | Keep it; do not report it as unfamiliar |
| A connection you never obtained | Use the appropriate “Not My Number” report after checking |
| Your own connection that is no longer needed | Review the “Not Required” option and its consequences |
| An entry you cannot identify confidently | Check family records and contact the operator first |
Save the acknowledgement or reference shown after reporting. Keep it private and use the official tracking or support route when following up. If you reported a legitimate connection by mistake, contact the telecom provider promptly and follow its re-verification instructions.
Before giving up a number you own, move banking notifications, account recovery and other essential services to a number you retain. This preparation reduces avoidable lockouts. Reporting an unneeded connection should not be your first step if important accounts still depend on it.
The limit is not simply “nine SIMs per Aadhaar”
DoT’s published subscriber re-verification instructions dated 7 December 2021 describe a maximum of nine connections per individual across providers, with a limit of six in Jammu & Kashmir, Assam and North-East licensed service areas. This is a subscriber-based rule, not an extra allowance for each identity document.
Check the current DoT instructions or ask your provider if your situation involves multiple service areas or a disputed connection. This guide does not calculate penalties or make a legal determination about an individual subscriber.
If OTP or the results cause problems
Check the entered number and whether the phone can receive messages. Follow the on-screen retry timing rather than repeatedly requesting codes. If the problem continues, use the official support route or contact your operator. Do not accept remote-access help from an unsolicited caller.
A list review does not by itself protect every account from fraud or prove that an existing number cannot be misused. Continue checking account security and suspicious communications separately. If money has been lost, contact the financial provider promptly through its official channel; a telecom report is not a refund request.
Frequently asked questions
Can I check someone else’s connections?
This service is for authenticated subscribers reviewing their own connections. It is not an unrestricted number-to-person search.
Is Aadhaar entry part of the basic login?
The government service description lists mobile number, captcha and OTP. Operator re-verification may have separate document requirements.
Will a report close the SIM immediately?
Do not assume so. Re-verification and provider action are involved. Keep the acknowledgement and follow official status information.
Do I need to keep the app installed?
Sanchar Saathi is available as a portal as well as an app. A December 2025 government clarification says users may deactivate or delete the app. Use your phone’s normal uninstall control if you no longer want it.
Keep complaint references before removing the app. Uninstalling software is separate from withdrawing a submitted report or cancelling a mobile connection. Use the service’s official procedure for those actions.
Update policy: We update this mobile-number checking guide when official service instructions change. AppTN is an independent information site, not DoT or Sanchar Saathi.
