Active SIM Checking Process: Today, your identity linked to your mobile number is your security. If a fraudulent SIM is active in your name, it can pose a major threat. Here's how to check how many SIMs are registered in your name.

Active SIM Checking Process: In the digital age, mobile numbers are no longer limited to just calls or internet access. Today, banking, UPI, social media, and even government services are linked to mobile numbers. Therefore, if a fraudulent SIM is active in your name, it can directly threaten both your identity and your finances. Often, people are unaware that more than one number is registered under their Aadhaar card.

This is why cases of fraud, fake accounts, and OTP theft are increasing. The good news is that you no longer need to visit a telecom office. Through the Department of Telecommunications' TAFCOP portal, you can check from the comfort of your home how many SIMs are active in your name and easily block those that don't belong to you.

How to check how many SIMs are registered in your name?

The TAFCOP (Telecom Analytics for Fraud Management and Consumer Protection) portal is the government's official platform where you can see all the mobile connections linked to your Aadhaar card. To do this, first open the TAFCOP portal. Enter your 10-digit mobile number, fill in the captcha, and click on Send OTP. After entering the OTP received on your phone, you will be logged in.

Now, a complete list will appear on your screen showing how many SIMs have been issued in your name, which ones are active, and which are inactive. If you see a number in the list that is not yours or is no longer needed, select the "This is not my number" or "Not required" option next to it. After pressing the report button, the re-verification process will begin. There is no charge for this entire process.

Consequences of not blocking fraudulent SIMs

The biggest advantage of removing fraudulent SIMs is that no illegal activity can be carried out in your name. This significantly reduces the risk of bank fraud, fake calls, social media scams, and identity theft. Your mobile data and banking OTPs remain more secure. Additionally, SIM cards that are no longer needed can be easily deactivated.

It's best to check the SIM cards registered in your name at least once a month. If you notice any suspicious numbers, report them immediately. Do not share your Aadhaar number or mobile number with strangers, and never share your banking details or OTPs.
