What Sanchar Saathi TAFCOP does

Sanchar Saathi is a citizen service of the Department of Telecommunications. It helps mobile users check and report telecom-related misuse.

Through Sanchar Saathi, citizens can:

  • Check mobile connections issued in their name.
  • Report suspected fraud communication through Chakshu.
  • Block a lost or stolen handset through CEIR.
  • Check whether a mobile handset IMEI is genuine.
  • Check trusted contact details of important organisations.

The TAFCOP facility, now available through Sanchar Saathi, helps a mobile subscriber check how many mobile connections are active in their name. It also allows reporting of mobile connections that are not required or not taken by the subscriber.

How to check mobile numbers in your name

Step 1: Open Sanchar Saathi

Go to www.sancharsaathi.gov.in.

Use the official portal only. Do not enter OTPs on look-alike websites.

Step 2: Choose Citizen Centric Services

On the home page, select Citizen Centric Services.

Step 3: Select Know Mobile Connections in Your Name

Choose Know Mobile Connections in Your Name.

You can also open the TAFCOP page directly here: TAFCOP Know Mobile Connections in Your Name.

Step 4: Enter your mobile number

Enter your current mobile number.

This mobile number is used for OTP verification.

Step 5: Verify OTP

Enter the OTP received on your phone.

Do not share this OTP with anyone.

Step 6: View numbers issued in your name

After OTP verification, the portal shows mobile connections linked to your name.

Check each number carefully. Some digits may be masked.

Step 7: Mark the unknown number

If a number was not taken by you, mark it as not mine or not taken by me, depending on the option shown.

If a number was taken earlier but is no longer needed, mark it as not required.

Step 8: Submit the report

Submit the report on the portal.

Do not close the page until the request is submitted.

Step 9: Save the acknowledgement

Save the acknowledgement number or request ID.

Take screenshots of:

  • the number list,
  • the reported unknown number,
  • the final acknowledgement page.

Step 10: Recheck after a few days

Recheck Sanchar Saathi after a few days.

Do not assume instant disconnection. The telecom service provider may need to verify the report.

What if the number is yours but old

Do not wrongly report an old family number.

First check with family members. Old SIMs used by parents, children, spouse, staff, drivers, or office users may appear in your name.

Also check whether you took a SIM years ago and forgot about it.

Only report a number if you are sure:

  • it was not taken by you, or
  • it was taken by you but is no longer required.

Wrong reporting can create problems for a genuine user in your family or office.

What if the number is being used for fraud

Use this section if the unknown SIM may have caused serious misuse.

This includes cases where:

  • a police notice came,
  • your bank account got frozen,
  • a loan app or wallet was opened,
  • a WhatsApp account was created,
  • OTPs stopped coming,
  • SIM swap happened,
  • recovery calls came for a loan you never took,
  • cyber cell contacted you,
  • the SIM was linked to fake trading, betting, courier scam, digital arrest scam, or UPI fraud.

Escalation order

  1. Save all evidence first.
  2. Report the number on Sanchar Saathi TAFCOP.
  3. Call your telecom operator and ask for fraud/KYC verification.
  4. File a complaint at cybercrime.gov.in.
  5. Call 1930 if money loss has happened.
  6. File a written complaint at the local cyber police station.
  7. Send a written complaint to the telecom operator nodal officer or appellate authority.
  8. Inform your bank and freeze risky channels if OTP, UPI, net banking, or card access is at risk.
  9. Pull your CIBIL report if loan misuse is suspected.

Do not delay if money has moved from your account. For financial fraud, speed matters.

Sample cyber police complaint

Subject: Complaint regarding unknown SIM issued in my name and suspected identity misuse

To, The Officer in Charge, Cyber Police Station, [City / District]

I am filing this complaint because an unknown mobile number appears in my name on Sanchar Saathi TAFCOP.

The number is [masked number]. I have not taken this SIM connection. I suspect misuse of my identity documents, including Aadhaar and PAN details.

I am concerned that this unknown SIM may be used for OTP theft, impersonation, bank fraud, UPI misuse, loan app misuse, wallet account creation, WhatsApp misuse, or other cyber offences.

I request you to register my complaint and take necessary action as per law.

I also request preservation and investigation of:

  • CAF and KYC documents used for the SIM,
  • activation date and time,
  • retailer or outlet details,
  • photograph used for activation,
  • address proof used,
  • IP logs and device details where applicable,

Regards, [Name] [Mobile number] [Address] [Date]

RTI angle

RTI has limits in private telecom matters.

RTI cannot be used directly against private telecom operators because they are not public authorities under the RTI Act in the normal course.

You can use RTI with the Department of Telecommunications or another public authority for:

  • policy details,
  • action taken status on a complaint sent to that public authority,
  • general telecom enforcement information,
  • rules or circulars about mobile connection verification.

For individual SIM KYC records, do not expect RTI to get private customer records, CAF copies, CDR, or private telecom data.

For those records, use:

  • telecom operator grievance channel,
  • police investigation,
  • cyber police complaint,
  • court process, where required.

Do not try to obtain CDR, KYC records, or private subscriber records through unofficial channels.

FAQs

How do I check how many SIMs are in my name?

Go to Sanchar Saathi, choose Citizen Centric Services, and select Know Mobile Connections in Your Name. Enter your mobile number, verify OTP, and check the list shown on the portal. If you see an unknown mobile number, report it from the same page and save the acknowledgement.

What should I do if I find an unknown mobile number?

Take a screenshot first. Then mark the number as not mine, not taken by me, or the closest available option on TAFCOP. Save the request ID. Contact your telecom operator and ask them to verify the KYC. If there is fraud or money loss, file a cyber complaint.

Can someone take a SIM using my Aadhaar?

A SIM should not be issued without proper KYC. But identity misuse can happen if documents, photos, or personal details are misused. If an unknown SIM appears in your name, report it on Sanchar Saathi and ask the telecom operator to verify the KYC records.

Will Sanchar Saathi block the SIM immediately?

Do not assume instant blocking. Sanchar Saathi allows you to report a number that is not required or not taken by you. The telecom service provider may verify the report before action. Save the acknowledgement and follow up with the operator if the number continues to appear.

Should I file police complaint for every unknown number?

If there is only an unknown number and no misuse, first report it on Sanchar Saathi and to the telecom operator. File a cyber complaint or police complaint if there is fraud, OTP theft, impersonation, loan misuse, WhatsApp misuse, UPI misuse, or police/cyber cell contact.

What if the number belongs to my family?

Do not report it as fraud. Many old family, staff, driver, or office numbers may be in one person’s name. Check with family members first. If it is a genuine number but no longer needed, use the not required option instead of saying it was never taken by you.

Can I get the full KYC documents of the fraud SIM?

You can ask the telecom operator to verify the KYC, CAF, activation date, outlet, photograph, and address proof. The operator may not share full private records directly. Police can seek records through lawful process during investigation.

Can RTI get me the SIM owner details?

No, RTI is not the right route to get private SIM owner details, KYC documents, or call records from a private telecom operator. RTI can be used with DoT or another public authority for policy, complaint status, or general enforcement information.

What if a fraud SIM caused bank account freeze?

Collect the bank freeze message, complaint number, Sanchar Saathi screenshot, and cyber complaint acknowledgement. Ask the bank for the reason and reference number. File or update your cybercrime.gov.in complaint and visit the cyber police station with the evidence pack.

What if a loan was taken using the fraud SIM?

Pull your CIBIL report and check all loan accounts. Contact the lender in writing and deny the loan if it is not yours. File a cyber complaint and police complaint. Attach the TAFCOP screenshot, loan messages, recovery calls, and identity theft evidence.

What if WhatsApp was created using that number?

Take screenshots of the WhatsApp misuse if available. Report the number on TAFCOP. File a cyber complaint if impersonation, fraud, extortion, loan recovery, or UPI fraud is involved. Also warn family members not to send money or documents to that account.

How often should I check TAFCOP?

Check TAFCOP every few months. Also check after losing documents, changing phones, receiving suspicious OTPs, getting loan recovery calls, or noticing unknown bank, UPI, wallet, or WhatsApp activity.
