Mobile Number Validation (MNV): How It Stops SIM Fraud

The Mobile Number Validation (MNV) platform is a new government system that lets a bank, payment app, or other service check that the mobile number you gave them genuinely belongs to you before they open an account or process money. It is run by the Department of Telecommunications (DoT) and was created by the Telecommunications (Telecom Cyber Security) Amendment Rules, 2025. The aim is simple: stop fraudsters from using fake or borrowed mobile numbers to set up “mule” accounts in your name.

When you open a bank account, sign up on an e-commerce site, or get a digital wallet, you hand over a mobile number. Until now, the service had no reliable, official way to confirm that the number is really linked to you and is active and genuine. Fraudsters exploited this gap by using numbers obtained on someone else's identity to open accounts that move stolen money.

MNV closes that gap. A registered service (the rules call it a “Telecom Identifier User Entity”) can now ask the MNV platform whether a given mobile number matches the telecom records for that user. The platform replies with a match or no-match result. For you, this means fewer fraudulent accounts opened in your name, and a stronger check before money moves.

India has seen a sharp rise in mule accounts: bank accounts opened using stolen or borrowed identities and mobile numbers, then used to receive and launder the proceeds of online scams. A single fake number can be used to create accounts across many platforms.

The government's earlier tools, such as Sanchar Saathi and the Financial Fraud Risk Indicator, helped flag suspicious numbers. MNV adds a missing piece: a real-time way for any onboarding service to confirm that a number truly belongs to the person presenting it, before the account is opened. This makes it much harder to build a fraud network on fake numbers.

MNV is created by new Rule 7A (“Validation of telecommunication identifiers”) inserted into the Telecommunication Cyber Security Rules through the Telecommunications (Telecom Cyber Security) Amendment Rules, 2025. The operative notification is G.S.R. 771(E) dated 22 October 2025, issued by the Department of Telecommunications, Ministry of Communications.

There was a brief confusion afterwards: the same rules were accidentally republished as G.S.R. 796(E) dated 29 October 2025. DoT has since clarified that this was an inadvertent republication and rescinded it through G.S.R. 863(E) dated 25 November 2025. The original 22 October 2025 amendment stands and is in force. The framework is described in the official PIB release (PRID 2195208) and on the DoT and Sanchar Saathi portals.

The platform works as a quick request-and-answer check:

1. Step 1 - Request. A registered service (a bank, lender, e-commerce site, or other Telecom Identifier User Entity) sends the mobile number you provided to the MNV platform for validation. A government agency authorised under the rules can also place such a request.
2. Step 2 - Check. The platform checks that number against the subscriber records held by the telecom licensee or authorised entity.
3. Step 3 - Result. The platform returns a result, broadly a match or a no-match, telling the service whether the number genuinely belongs to that user.
4. Step 4 - Decision. Using that result, the service decides whether to go ahead, ask for more proof, or refuse, so a fake number is stopped before an account is opened.

The validation is meant to be near real-time and must follow data-protection law. There is a nominal per-validation fee for using the platform, which the rules say is shared between the government agency that runs the platform and the entity providing the validation. The final notification did not fix a single rupee amount in the rules; an earlier June 2025 draft had proposed a small per-request charge, but that figure was not carried into the final rule, so no fixed amount should be treated as current law.

You do not have to register for MNV or do anything to switch it on. It works behind the scenes when a service onboards you. The practical benefits and protections include:

• Fewer fake accounts in your name. A fraudster who tries to open an account using a number that is not genuinely yours is more likely to be caught at the door.
• Safer onboarding. Banks and apps get a reliable check before linking your number to a financial account, reducing impersonation and account-takeover risk.
• Stronger fraud net overall. MNV complements Sanchar Saathi, the Financial Fraud Risk Indicator (FRI), and the nine-SIM ownership limit, making the whole system harder to abuse.
• A possible small fee. Because validation may carry a nominal charge, some services might pass on a tiny cost, but this is for the service, not a fee you pay to the government for owning a number.

If your mobile number is being misused, act quickly:

1. Check how many SIMs are active on your identity using the TAFCOP / Sanchar Saathi tool, and report any you do not recognise so they can be blocked.
2. If your number was taken over, follow the steps to recover from SIM-swap fraud and inform your bank at once.
3. Report financial cyber fraud immediately on the national helpline 1930 and at cybercrime.gov.in; the sooner you report, the better the chance of freezing the money.
4. Know your limits: you may legally hold only a capped number of SIMs, explained in our guide to the nine-SIM-per-person limit under the Telecom Act.

MNV is a Department of Telecommunications platform created by Rule 7A of the Telecommunications (Telecom Cyber Security) Amendment Rules, 2025. It lets registered services check that a mobile number genuinely belongs to the user who provided it, returning a match or no-match result to curb mule accounts and SIM fraud.

No. As an ordinary citizen you do not register for MNV or pay a fee to the government for it. The platform works in the background when a bank, lender, or app verifies a number during onboarding. Any nominal per-validation fee is paid by the requesting service, not directly by you.

MNV is a validation check used by services to confirm a number belongs to you. It is not designed to stop your genuine OTPs or block a number you legitimately own. Its purpose is to catch fake or borrowed numbers used for fraud, not to disrupt honest users.

Sanchar Saathi helps you find and block SIMs taken in your name, and the Financial Fraud Risk Indicator flags numbers already linked to fraud. MNV adds a real-time check at the point of onboarding, confirming the number actually belongs to the user before an account is opened. Together they strengthen the fraud-prevention net.

Report the unrecognised SIMs through the Sanchar Saathi or TAFCOP tool, call the cyber-fraud helpline 1930 and file a complaint at cybercrime.gov.in, and inform any bank where an account may have been opened. Keep written records of every complaint for follow-up.

1. Use the Sanchar Saathi / TAFCOP tool to see how many SIMs are active on your identity and report any you do not recognise.
2. If you suspect financial fraud, call 1930 and file at cybercrime.gov.in without delay.
3. Read our guides to the Financial Fraud Risk Indicator and the nine-SIM limit to protect yourself.
