A mobile number issued using someone’s identity can remain active without their knowledge, creating opportunities for identity misuse and telecom-related fraud. India’s Department of Telecommunications (DoT) provides a free facility called TAFCOP, which allows subscribers to check mobile connections registered in their name and report numbers they do not recognise.
Available through the government’s Sanchar Saathi platform, the service helps people identify unauthorised SIM connections without visiting multiple telecom operators. The facility is particularly relevant because mobile numbers are commonly linked to banking, digital payments and online account verification.
What Is TAFCOP and Why Does It Matter?
TAFCOP stands for Telecom Analytics for Fraud Management and Consumer Protection. It was developed by DoT to help subscribers identify connections issued against their identity documents.
The service is integrated into the Sanchar Saathi portal, which also provides facilities for reporting suspicious communications, blocking lost handsets and checking mobile device authenticity.
The government’s October 5, 2026 update stated that more than four crore citizen requests concerning mobile connections had been resolved through Sanchar Saathi. The figure reflects the scale of public use, not the number of confirmed fraud victims.
How to Check SIM Cards Registered in Your Name
The TAFCOP verification process is designed for ordinary mobile subscribers and does not require technical knowledge.
Visit the official Sanchar Saathi website and select Know Your Mobile Connections. Enter your active mobile number, complete the displayed verification requirements and request a one-time password.
After entering the OTP, the service displays mobile connections associated with your identity in its available records. Review the numbers carefully, including old connections that may no longer be in use.
The DoT’s original TAFCOP documentation confirms that users authenticate through their mobile number and OTP before accessing connection information. The records should not be treated as a complete history of every number a person has ever owned.
What Should You Do If an Unknown Number Appears?
Finding an unfamiliar number does not automatically establish criminal activity. It could reflect an old connection, an administrative discrepancy or a SIM issued without proper authorisation.
The portal allows subscribers to identify connections they never obtained and those they no longer need. The relevant reporting options are generally labelled Not My Number and Not Required.
A number marked as unauthorised is referred for action through the telecom verification process. DoT’s instructions provide for reverification, with connections that fail the required checks subject to disconnection.
This distinction matters because submitting a report does not necessarily mean that the number is immediately disconnected. The operator may need to examine subscriber records and complete the prescribed verification procedure.
How Many SIM Cards Can One Person Have?
Under DoT’s subscriber rules, an individual can generally hold up to nine mobile connections across telecom operators. The prescribed limit is six in Jammu and Kashmir, Assam and the northeastern states.
The limit applies across operators, not separately to each company. Subscribers exceeding the permitted number may face reverification and disconnection procedures. mobile connections reached None.
How TAFCOP Helps Prevent Identity Misuse
Unauthorised SIM connections can potentially be used for impersonation, suspicious communications and other unlawful activities. However, discovering an unfamiliar connection does not prove that the subscriber has committed an offence.
DoT also operates Chakshu, a separate Sanchar Saathi facility for reporting suspicious calls, SMS messages and WhatsApp communications.
In July 2026, the government stated that more than 88 lakh suspicious mobile connections had been disconnected after failing reverification. This was a broader telecom enforcement figure, not solely the result of TAFCOP complaints.
People who have suffered financial cybercrime should report it through the National Cyber Crime Reporting Portal or call 1930. TAFCOP reporting does not replace a cybercrime complaint.
