Post Highlights
Have you ever wondered if someone is using a SIM card registered under your Aadhaar without your knowledge? It happens more often than you think. The good news is that the Government of India has made it very easy to check and fix this — through the TAFCOP portal, now part of the Sanchar Saathi platform.
What is TAFCOP Portal?
TAFCOP Dgtelecom is started by the Indian Department of Telecommunications (DoT). TAF stands for “Telecom Analytics for Fraud management and Consumer Protection”. The main objective of TAFCOP is to ensure that all telecom equipment is safe for use in the Indian telecom network, in line with national and international standards.
TAFCOP portal, tests and verifies telecommunication equipment such as mobile phones, wireless devices, telecom cables and other telecom equipment on the basis of some standards. In India, these rules are set by International Electrotechnical Commission (IEC) and Telecommunication Engineering Center (TEC)
In addition, the TAFCOP also plays an important role in enforcing Indian government regulations related to telecommunication equipment. Overall, the TAFCOP Portal plays a vital role in ensuring the security and reliability of telecom equipment used in India and promoting the growth of the Indian telecom industry.

How to Login and Check Active SIM Cards on TAFCOP Portal
Follow these steps to see how many active SIM cards have been issued in your name:
Visit the TAFCOP DGTELECOM website with the help of a browser on your phone or computer.
Enter your mobile number and click on “Generate OTP” button. You will receive One-Time Password (OTP) on your registered mobile number. Enter the OTP in the space provided and click on the “Verify OTP” button.
Once you are logged in, your dashboard will show you all mobile connections registered under your Aadhaar card. The total number of connections is shown at the top.
Now you will see a list of all the SIM cards that have been issued through your Aadhaar card.
If you find that there are some SIM cards that you have not authorized, immediately contact your service provider and get those SIM card blocked.
Track your lost or stolen Mobile Phone by IMEI Number.
What to Do If You Find an Unknown SIM
This is the most important part — and most people get it wrong.
For each number in the list, you will see three options:
- Required – The number is yours and you want to keep it. No action needed.
- Not Required – The number is registered under your name but you want it closed (for example, an old number you no longer use).
- This is not my number – Use this if the number was never yours and you suspect it was registered fraudulently.
Do not use “Not Required” for fraud cases. Selecting “Not Required” only closes the connection voluntarily. It does not trigger a fraud investigation. Always select “This is not my number” for any connection you did not authorise.
Once you submit your report, save the reference ID that appears on the screen. This is the only way to track the status of your complaint later, so take a screenshot before closing the page.
Allowed SIM limit: A person can have a maximum of 9 SIM cards registered under one name in India. If your count is higher than that and you did not apply for those extra connections, report them immediately.
Update Aadhaar in TAFCOP Portal
Follow these steps to update your Aadhaar card details on the TAFCOP portal:
1) Visit TAFCOP Portal https://www.tafcop.dgtelecom.gov.in/.
2) Complete the OTP verification by entering your mobile number here. Once logged in, click on the “Aadhaar Authentication” tab.
3) Enter your Aadhaar number and click on “Send OTP” button.
4) Now you will receive an OTP on the registered mobile number linked with your Aadhaar. Enter the OTP in the space provided and click on the “Verify OTP” button.
5) After Aadhaar successfully authenticated, now you can update your Aadhaar details by clicking on the “Update Aadhaar” button.
6) If you want to change your aadhaar card information such as name, address, date of birth, etc. then edit this information here. For this you need to upload a scanned copy of the supporting document that you are using to update your Aadhaar details.
7) Review provided details and make sure that they are correct. Click on the “Submit” button to complete the update process.
Once your request is processed and verified by the concerned authorities, your updated Aadhaar details will appear in the TAFCOP portal.
How to Report Fraud Calls via Chakshu
If someone called or messaged you pretending to be from a bank, DoT, TRAI, or any government department, you can report that separately using Chakshu.
1) Go to https://sancharsaathi.gov.in/sfc/
2) Select the type of fraud — call, SMS, or WhatsApp message.
3) Enter the details and submit your report.
Chakshu is specifically for suspicious communications received within the last 30 days. It is different from TAFCOP — TAFCOP is for managing your SIM connections, while Chakshu is for reporting fraud calls and messages.
According to a government statement in the Rajya Sabha in February 2026, over 7.7 lakh suspected fraud communications have been reported through Chakshu since launch, leading to nearly 39 lakh mobile connections being disconnected.
