Unknown SIM in Your Name? Check Sanchar Saathi and Report It Safely

A phone number is more than a way to receive calls. It can be used for banking alerts, account recovery, delivery confirmations and identity checks. That is why discovering a mobile connection issued in your name without your knowledge deserves attention. The right first step is not to call an unknown number or pay a person who promises to delete it. It is to check the official telecom service, understand what the list means and submit the correct report.

India’s Department of Telecommunications offers Know Mobile Connections in Your Name, often associated with the earlier name TAFCOP, through Sanchar Saathi. The official Department of Telecommunications services dashboard describes it as a way to review connections issued in a subscriber’s name. This guide explains the identity audit, not how to block a stolen handset. That is a different service.

What the check can tell you—and what it cannot

The service is designed to display mobile connections associated with the subscriber identity used by telecom providers. It can reveal a number you have forgotten, a family connection you previously authorised, or one you genuinely do not recognise. The appearance of an unfamiliar number is a reason to investigate; it is not, by itself, proof that a particular person committed fraud. Old records, shared family arrangements and mistaken associations are possible.

Likewise, the list is not a complete report of every online account that has ever used your phone number. A number linked to a social-media login is not necessarily a SIM issued under your identity. Do not confuse the telecom identity audit with an app-permission audit, an Aadhaar authentication history or a handset’s IMEI check.

Step 1: start from the government service

Open Sanchar Saathi by typing its address yourself or follow the official telecom dashboard to Know Mobile Connections in Your Name. Avoid sponsored search results, copied messages and lookalike domains. A third-party website may reproduce the colours and wording of a government page while collecting personal details. If a link arrives by SMS claiming a connection will be blocked immediately, do not treat urgency as proof of authenticity.

Have an active mobile number that you control and can receive an OTP on. Follow the current portal’s instructions for the mobile number, verification code or captcha if shown, and one-time-password verification. The screens can change. You should not need to share your OTP with a call-centre agent, shopkeeper or stranger on a messaging app. Enter it only into the verified government flow you opened independently.

Step 2: review the displayed connections carefully

After authentication, inspect the numbers and the choices offered beside each. Take a moment to consider older prepaid SIMs, a secondary work number and any connection originally acquired for a relative. If a number is partly masked, do not guess the full digits from memory. Cross-check your old recharge records, bills or provider accounts before reporting a number you still use.

A practical method is to make a private list of three groups: numbers you currently control, numbers you recognise but no longer need, and numbers you cannot account for. Keep that list off public social media. There is no benefit in publishing screenshots of the portal, especially when they expose mobile numbers or identity-linked details.

Step 3: choose the reporting option that matches the facts

The distinction between This is not my number and Not required matters. The first is intended for a connection you did not obtain or authorise. The second is for a connection associated with you that you no longer need. Treat them as different reports, not interchangeable buttons for removing a line from the screen. If the portal’s wording changes, read the on-screen explanation before submitting.

For example, imagine you once used a second SIM for a temporary job and have now stopped using it. If it genuinely belonged to you, an unnecessary-connection report is more appropriate than alleging it was never yours. Conversely, if a number appears that you have never seen and no family member can explain, reporting it as not yours preserves the nature of the concern for the telecom provider’s follow-up.

What happens after you report an unknown number?

The Department of Telecommunications’ Sanchar Saathi programme provides reporting and telecom-provider verification routes. A report is not the same as an instant judicial finding or a guarantee that a connection has been disconnected at that second. The operator may need to reverify subscriber information and take action under applicable rules. Save any acknowledgement or reference identifier the portal provides, along with the date and the option you selected.

Check the status through the same official service rather than repeatedly submitting the same number. If the number is actively causing harm—such as account takeover attempts or impersonation—also contact the relevant bank or service provider and consider the appropriate cybercrime-reporting channel. The telecom connection report addresses one part of the risk, not every downstream account.

Protect the number you actually use

Do not let the identity audit distract from the security of your primary SIM. Keep your provider account details current, use a strong device lock, enable account-specific two-factor authentication where available, and review the recovery methods on important services. If your phone is missing, the lost-device process is separate from reporting an unauthorised connection. Our guide to passkey recovery after losing a phone explains why backup sign-in methods matter before an emergency.

An Aadhaar number is not a universal login password, and locking Aadhaar biometrics does not automatically cancel telecom connections. If you are reviewing broader identity security, the distinction between Aadhaar biometric lock and Aadhaar number lock is worth understanding separately. Each tool protects a different part of your digital identity.

What if the list is incomplete or appears wrong?

First verify that you used the intended government portal and a number associated with your own subscriber identity. Then compare the results with provider statements and old account records. A missing entry does not prove a SIM is inactive, and an unexpected entry does not prove current misuse. If a provider gives conflicting information, ask it for a written clarification or complaint reference and preserve the reply.

If you cannot receive the verification OTP, do not hand over control of another person’s phone or ask a shop to complete the audit using its own number. Contact your telecom provider through its published support route for help recovering access to your number or updating subscriber records. Keep personal identity documents out of unverified email and messaging channels.

A five-minute audit to repeat when circumstances change

You do not need to monitor the portal every morning. A sensible trigger is a new SIM purchase, the closure of an old connection, a suspected identity compromise or a provider notice that does not match your records. Check, reconcile, report if needed and save the outcome. Periodic review is useful, but repeatedly filing speculative complaints can make a genuine issue harder to track.

A family can also make a private inventory of which person is the actual registered subscriber for each number. That is especially helpful when a parent originally acquired a connection later used by an adult child. The goal is accurate records, not to infer legal ownership from who physically holds the handset.

Frequently asked questions

Does Sanchar Saathi show every app using my mobile number?

No. It concerns telecom connections issued in a subscriber’s name. Apps that use a number for login are a different question and must be reviewed in the relevant app accounts.

Is an unknown number automatically evidence of fraud?

No. Treat it as an unexplained record that needs checking and, where appropriate, reporting. The provider’s verification process is important.

Should I select Not required for a SIM I never obtained?

Use the portal’s option intended for a number you did not take, normally This is not my number, rather than the voluntary no-longer-needed choice.

Can someone else log in for me using my OTP?

Do not disclose an OTP to an unsolicited caller or third party. Use the government portal yourself, or seek assistance from your provider’s verified support channel.

Does this service replace a cybercrime complaint?

No. It helps review telecom subscriber records. Financial loss, impersonation or other criminal activity may require separate reporting and account-protection steps.
