You may have one or two SIM cards in your phone—but how many mobile connections are actually registered in your name?
An old SIM you stopped using, a number obtained years ago, or in a more serious case, a connection obtained using your identity could still be associated with you.
The Government of India provides a service called TAFCOP, available through the Department of Telecommunications’ Sanchar Saathi initiative, that allows you to check mobile connections issued in your name and report connections that you either don’t need or never obtained.
This guide explains what TAFCOP is, how to use it, what to do if you find an unknown number, and how to make sure you’re using the genuine government website.
What Is TAFCOP?
TAFCOP stands for Telecom Analytics for Fraud Management and Consumer Protection.
It is a Department of Telecommunications (DoT) service designed to help Indian mobile subscribers identify mobile connections issued in their name.
According to the Department of Telecommunications, the “Know Mobile Connections in Your Name” facility allows citizens to:
- Check mobile connections taken in their name.
- Identify connections they no longer require.
- Report mobile connections they did not obtain.
- Request action against unauthorized connections.
The service forms part of the Government of India’s broader Sanchar Saathi telecom-security initiative.

Why Should You Check the SIM Cards Registered in Your Name?
A mobile number is no longer used only for calling.
Your phone number may be connected to banking, UPI, government services, email accounts, social-media accounts, two-factor authentication and numerous other digital services.
This makes unauthorized telecom connections an important identity and security concern.
The Department of Telecommunications specifically describes Sanchar Saathi as an initiative intended to strengthen subscriber security and combat misuse of telecom resources, including fraudulent connections.
Checking TAFCOP periodically can therefore answer a simple but important question:
Are all the mobile connections registered in my name actually mine?
How to Check Mobile Numbers Registered in Your Name Using TAFCOP
The process is straightforward.
Step 1: Open the Official TAFCOP Portal
Visit:
Be careful with similarly named websites appearing in search results or messages. For a government telecom service, verify that you’re using an official government/DoT Sanchar Saathi service before entering personal information.
Step 2: Enter Your Mobile Number
Enter your active 10-digit Indian mobile number.
The mobile number is used to authenticate you before information about connections associated with your identity is displayed.
Step 3: Complete the CAPTCHA
Enter the CAPTCHA displayed on the page.
CAPTCHA helps prevent automated systems from abusing the service.
Step 4: Request the OTP
Select the option to receive an OTP.
An OTP (One-Time Password) will be sent to your mobile number.
Never share this OTP with another person claiming that they need it to “check your SIM cards” for you.
Step 5: Verify the OTP
Enter the OTP received on your phone.
The original DoT description of TAFCOP explains that the subscriber enters their mobile number and authenticates using an OTP before the system provides information about connections associated with them.
Step 6: Review the Mobile Connections
After successful authentication, review the connections displayed by the service.
Go through them carefully.
Ask yourself:
Do I recognize every connection shown here?
Don’t automatically report an unfamiliar-looking number. First consider whether it could be an old SIM, secondary number, data connection or another connection you previously obtained and forgot about.
What If You Find a Mobile Number That Isn’t Yours?
This is where TAFCOP becomes particularly useful.
DoT says the service allows users to report mobile connections that are either:
1. Not required, or
2. Not taken by the subscriber.
If you genuinely don’t recognize a connection, use the reporting option available through the portal.
Follow the instructions displayed by TAFCOP and submit the appropriate request.
Don’t report a number simply because you don’t immediately recognize it. Verify first, particularly if you have used multiple SIM cards over the years.
What Happens After Reporting an Unknown Connection?
Submitting a report is essentially a request for action concerning the connection.
The exact subsequent process can depend on the case and telecom operator, so follow the status and instructions provided through the official system rather than assuming that reporting a number means it disappears instantly.
Sanchar Saathi also maintains a dedicated TAFCOP feedback mechanism that accepts request-related feedback and asks for the associated request ID.
Keep any request/reference ID generated after submitting your report.
It may be useful if you need to follow up later.
Is TAFCOP a Genuine Government Website?
Yes. TAFCOP is an official service of the Department of Telecommunications (DoT), Ministry of Communications, Government of India, under the Sanchar Saathi initiative.
DoT describes the service as “Know Mobile Connections in Your Name.”
The government’s Department of Telecom eServices portal also identifies TAFCOP as the service through which users can check mobile connections issued in their name.
Because telecom-security tools attract imitation websites and scam messages, it’s still important to verify the domain before entering your mobile number or OTP.
TAFCOP vs Sanchar Saathi: What’s the Difference?
The names can be confusing.
Think of Sanchar Saathi as the larger platform and TAFCOP as one of its telecom-security services.
Sanchar Saathi includes facilities for areas such as:
- Knowing mobile connections issued in your name.
- Reporting suspected fraudulent communications through Chakshu.
- Blocking and tracing lost or stolen mobile handsets.
- Checking handset genuineness.
- Reporting certain international calls displaying Indian numbers.
So if your problem is specifically:
“I want to know which SIM/mobile connections are registered in my name.”
TAFCOP’s Know Mobile Connections in Your Name service is the relevant tool.
Can TAFCOP Help Prevent SIM-Related Fraud?
TAFCOP should be viewed primarily as an identification and reporting tool, rather than a guarantee that telecom fraud cannot happen.
Its value is that it gives subscribers visibility.
Without such a facility, a person might have no easy way of discovering that an unwanted or unauthorized connection had been associated with their identity.
DoT has deployed Sanchar Saathi alongside broader analytics and fraud-detection systems to identify misuse of telecom resources.
Finding an unfamiliar connection early gives you an opportunity to report it rather than leaving it unnoticed.
Important Safety Tips When Using TAFCOP
Never share your OTP.
You should enter the OTP yourself on the official portal.
Check the domain carefully.
Avoid random links received through WhatsApp, SMS, Telegram or social media claiming to perform a “TAFCOP check.”
Don’t pay someone to perform the check.
Use the official government service directly.
Review before reporting.
Make sure the number isn’t an old or forgotten connection that actually belongs to you.
Save your request ID.
If you report a connection, retain any acknowledgement or reference number generated by the system.

Far fewer know exactly how many mobile connections exist in their name.
TAFCOP gives Indian subscribers a practical way to check.
