Is Your Aadhaar Linked to an Unknown SIM? Here’s How to Check

Your mobile number is now closely connected to many important parts of your digital life, from banking and online payments to social media and OTP-based services. But do you know how many mobile connections are registered under your identity?

If you have ever lost a SIM card, changed your number or shared identity documents while applying for a connection, it may be worth checking the mobile numbers associated with your Aadhaar-linked identity. An unfamiliar number could indicate that a connection has been issued using your details without your knowledge.

The government provides an online facility that allows consumers to check mobile connections registered in their name and report numbers they do not recognise.

How many SIM cards can one person have?

Under Department of Telecommunications (DoT) rules, an individual can have up to nine mobile connections registered in their name. The limit is intended to prevent misuse of telecom connections and help maintain greater accountability over SIM issuance.

Having multiple numbers does not automatically mean there is a problem. A person may legitimately use separate connections for personal, business or other purposes. However, an unfamiliar number appearing in the list deserves attention.

Why should you check your registered mobile connections?

Mobile numbers have become an important part of digital authentication. They can be connected to bank accounts, payment applications, social media profiles and numerous online services.

This means an unauthorised SIM registered using someone else's identity documents could potentially create security and financial risks. Fraudsters may misuse identity information to obtain connections and use those numbers for communication or fraudulent activities.

For consumers, regularly checking the connections issued in their name can therefore be an additional step in protecting their identity.

Sanchar Saathi offers a way to check

The government’s Sanchar Saathi platform provides a facility known as Telecom Analytics for Fraud Management and Consumer Protection (TAFCOP).

The service is designed to help people see the mobile connections issued in their name. It also provides a mechanism to report numbers that the user does not recognise.

The process can be completed online and requires the mobile number being used for verification.

Steps to check mobile connections issued in your name

Consumers can follow these basic steps:

1. Visit the government’s Sanchar Saathi platform.
2. Select the facility for checking mobile connections issued in your name.
3. Enter your 10-digit mobile number.
4. Complete the CAPTCHA displayed on the page.
5. Verify your identity using the OTP sent to your mobile number.
6. After successful verification, review the mobile connections associated with your identity.
7. If you find a number that you do not recognise, use the available reporting option on the platform.

The check is particularly useful for people who have held several mobile numbers over the years or may have forgotten about older connections.

What if you find an unfamiliar number?

Do not simply ignore an unknown connection. Review the list carefully and determine whether the number could belong to you or a family member for whom you had previously arranged a connection.

If you are certain that a number is not yours, the Sanchar Saathi facility allows consumers to report the connection. This gives the authorities and telecom ecosystem a mechanism to address potentially unauthorised connections.

The facility is intended to make it easier for consumers to identify possible misuse rather than discovering a problem only after a suspicious activity occurs.

SIM issuance rules have also been tightened

The government has introduced additional safeguards around the issuance and management of mobile connections. Digital KYC or e-KYC is required when new connections are issued, while bulk issuance of SIM cards to ordinary consumers has been restricted.

There are also safeguards concerning previously deactivated mobile numbers. A waiting period of 90 days applies before an inactive number can be reissued.

These measures are aimed at reducing the possibility of telecom connections being misused and improving accountability in the SIM issuance process.

A simple digital safety check worth doing

Aadhaar has made identity verification more convenient, but the increasing use of mobile numbers for digital services means consumers should remain aware of how their identity is being used.

Checking the mobile connections registered in your name through the government’s Sanchar Saathi platform is a relatively simple precaution. If an unknown number appears, reporting it promptly can help prevent potential misuse.

With mobile numbers increasingly serving as gateways to financial and online accounts, keeping track of the connections issued under your identity can be an important part of basic digital security.
