Mobile numbers have become an important part of a person's digital identity. Banking alerts, UPI services, social media accounts, government platforms and many other online services can be connected to a phone number. This makes it important to know exactly which mobile connections have been issued in your name.
If someone obtains a SIM using your identity without your knowledge, the connection could potentially be misused. Fortunately, the Department of Telecommunications (DoT) provides an online facility that allows consumers to check mobile connections registered in their name and report numbers they do not recognise.
The facility is available through the government's Sanchar Saathi portal, which incorporates services associated with TAFCOP—Telecom Analytics for Fraud Management and Consumer Protection.
Here's how consumers can check the connections associated with them and what they should do if an unfamiliar number appears.
Why Should You Check Mobile Connections Issued in Your Name?
An unknown mobile connection associated with your identity should not be ignored.
Mobile numbers can potentially be misused for activities such as impersonation, spam, cyber fraud and other unlawful transactions. If a number becomes part of an investigation, subscriber information associated with that connection may also become relevant.
This does not mean that the person whose identity was misused automatically becomes responsible for a crime committed by someone else. However, discovering and reporting an unauthorised connection promptly can help prevent complications.
Regularly reviewing your registered mobile connections is therefore a useful digital-safety precaution.
What Is TAFCOP?
TAFCOP stands for Telecom Analytics for Fraud Management and Consumer Protection.
The Department of Telecommunications developed the facility to help subscribers identify mobile connections issued in their name and take action regarding connections they do not recognise or no longer require.
These consumer services are now available through Sanchar Saathi, DoT's broader citizen-centric telecom safety platform.
Rather than searching for unofficial websites claiming to offer an "Aadhaar SIM check," consumers should use the government's official Sanchar Saathi service.
Do You Enter Your Aadhaar Number to Check SIMs?
This is an important point.
Although the service is often described online as a way to find "SIM cards linked with Aadhaar," consumers should not assume that they need to type their Aadhaar number into random websites.
The official Sanchar Saathi facility verifies access using your mobile number and OTP and then allows you to view mobile connections associated with your identity under the telecom subscriber records.
This also helps reduce the risk of users exposing sensitive Aadhaar information on fraudulent websites.
How to Check Mobile Connections Issued in Your Name
The process can be completed online through the Sanchar Saathi portal.
Go to the official Sanchar Saathi website and open the option for checking mobile connections in your name. Enter your active mobile number and complete the required CAPTCHA or verification process.
Select the option to receive an OTP.
An OTP will be sent to the entered mobile number. Enter the OTP to authenticate yourself.
After successful verification, the portal can display the mobile connections associated with your identity according to the available telecom records.
Carefully review every number shown on the screen.
You may see connections belonging to different telecom operators if multiple numbers have been issued under your identity.
What Should You Check in the List?
Do not simply look at the total number of connections. Review the displayed numbers individually and determine whether you recognise them.
Pay particular attention to a connection if:
- You do not remember ever obtaining the number
- The number does not belong to you
- You previously stopped using the connection but it still appears active
- You suspect your identity documents may have been misused
- A connection appears that you cannot associate with yourself
If all displayed connections are familiar and legitimately in use, no reporting action may be necessary.
What to Do If You Find an Unknown SIM
If you identify a connection that you do not recognise, use the reporting option provided through the official portal.
Depending on the current interface, the service allows consumers to indicate that a displayed mobile connection is not theirs or is not required.
For an unfamiliar connection that you never obtained, select the appropriate option indicating that the number does not belong to you and submit the request.
The matter can then proceed through the applicable verification and telecom-operator process.
Keep any reference or request number generated after submitting the report, as it may help you track the status later.
What If the Number Was Yours but You No Longer Need It?
There is a difference between an unknown connection and an old connection that you recognise.
If you previously obtained a number but no longer require it, choose the relevant option provided by the portal rather than incorrectly reporting it as a number that was never yours.
Similarly, do not report a legitimate connection simply because it is being used by a family member if the connection was knowingly obtained in your name. Instead, check with the telecom operator about the appropriate subscriber-registration process if ownership details need to be changed.
Beware of Fake SIM-Checking Websites
Because Aadhaar and SIM-related searches are common, fraudulent websites and messages may attempt to collect personal information.
Never share your Aadhaar number, OTP, banking PIN, UPI PIN or other sensitive credentials with an unknown website or caller claiming to "check all SIMs" registered against your identity.
An OTP received for authentication should be entered only on the legitimate service for which you requested it.
Users should also avoid clicking links received through suspicious SMS, WhatsApp messages or emails claiming that their SIM will immediately be blocked unless they complete verification.
Checking Your SIM Connections Can Prevent Bigger Problems
Reviewing the mobile numbers issued in your name takes only a short time but can reveal a connection that you did not know existed.
This is particularly useful if you have changed mobile numbers several times, lost an old SIM, shared identity documents during telecom verification in the past or have reason to believe your documents may have been misused.
If an unauthorised connection appears, reporting it through the official channel can help initiate verification before the number causes further complications.
The key precaution is simple: periodically check the mobile connections associated with your identity and immediately flag any number you genuinely do not recognise.
