Phone Lost or Stolen? How to Block It on CEIR

What should you do in the first hour after your phone is stolen?

Three things, in this order: block the SIM by calling your operator, secure the money apps by calling your bank, then file a police complaint. Only after you have a complaint number can you block the handset itself on the CEIR portal.

The order matters because the risks are different sizes. The handset is worth money. What is on the handset — your UPI apps, your banking OTPs, your WhatsApp — can cost you far more, and it is exposed from the moment the phone leaves your hand. So the SIM and the money come first, and the device block follows.

What is CEIR, and what does blocking actually do?

CEIR is the government's Central Equipment Identity Register, run by the Department of Telecommunications as part of its Sanchar Saathi platform. Blocking your IMEI on it stops the handset registering on any mobile network in India — so the phone becomes useless as a phone to whoever has it.

Every handset carries a unique 15-digit IMEI number, burned into the device rather than the SIM. When you report it lost, that number goes onto a blacklist shared with every Indian telecom operator. From then on the networks refuse to let the device connect, whichever SIM is in it.

The portal states that a phone is blocked within 24 hours of a successful request, and that once blocked it cannot be used on any network across India. It also makes two limits explicit, and they are worth understanding before you rely on this.

Can a blocked phone still be used with a different SIM?

No. The block attaches to the handset's IMEI, not to your SIM or your number, so swapping in a new SIM does not get around it. But the blacklist is shared among Indian operators only — the portal says blocking is effective within India, not internationally.

Two other things a block does not do. It does not wipe your data — that is a separate job for Find My Device or Find My iPhone, and it is the reason a screen lock matters. And it does not disable the device entirely: Wi-Fi and offline functions generally still work, because the block operates at the mobile network layer. What it removes is the phone's value as a working phone, which is what makes it worth doing even when you expect never to see the handset again.

Do you need an FIR to block a stolen phone on CEIR?

You need a police complaint, but not necessarily a full FIR. CEIR's own documentation asks for a "police complaint, i.e. FIR/LR", and the form field is labelled Police Complaint Number — so a Lost Report filed online with your state police is normally accepted.

The distinction is worth knowing because it decides how much of your day this takes.

Register an FIR rather than a lost report if the phone was actually taken from you, if you are claiming on insurance, or if anything was done with your bank or UPI accounts afterwards. Under the Bharatiya Nagarik Suraksha Sanhita 2023, information about a cognizable offence can be given electronically, and it can be registered irrespective of the area where the offence took place — the "zero FIR" — so being in a different city from where the phone went missing is not a reason to delay.

How do you block a stolen phone in India?

Go to the CEIR portal, open the "Block Stolen/Lost Mobile" form, and fill in your device details, IMEI, the loss details with your police complaint number, and your ID proof. Verify by OTP and submit. You get an 18-digit Request ID — save it.

Have these ready before you start, because the form asks for uploads and will not hold your place:

• Your IMEI number — 15 digits. Both, if the phone took two SIMs
• The mobile number(s) that were in the phone
• A copy of the police complaint — FIR or lost report — and its number
• Your ID proof. If you upload Aadhaar, mask it so only the last four digits show
• The purchase invoice for the handset, if you still have it
• Where and when it was lost, down to the police station area

You also need a working mobile number to receive the OTP, so use your duplicate SIM or a family member's phone. Once submitted, the portal generates an 18-digit Request ID. That number is the only handle you have on the request — it is how you check the status later, and it is what you will need to unblock the phone if it comes back. Write it down somewhere that is not the phone you just lost.

Is the CEIR portal free?

Yes. There is no fee at any step and the portal never asks for a payment — it has no payment field at all. If a website or a caller asks you to pay to "unblock" or "trace" a phone, that is a scam, not a government service.

This matters more than it sounds. Search for phone-blocking help and you will find lookalike sites that copy the government layout and charge for a form you can fill in yourself for nothing. Type the government address in directly rather than trusting a search advertisement, and remember that no genuine official will ever call to offer to trace your handset for a fee.

How long does CEIR blocking take?

The portal states the phone is blocked within 24 hours of a successful request. You can follow progress in the meantime using the "Check Request Status" option and your 18-digit Request ID.

How do you find your IMEI number without the phone?

The usual trick of dialling *#06# needs the handset, so use one of the records instead: the phone's box, the purchase invoice, or your Google or Apple account. All of them carry the IMEI.

• The box — printed on a sticker on the packaging, which is the reason to keep it
• The bill or invoice — retailers normally print the IMEI on it, and the e-commerce order page usually shows it too
• Android — sign in to Google's Find My Device from another device, select the phone, and open its information panel
• iPhone — sign in to your Apple account, open the Devices section, and select the phone
• Your operator — customer care can look up the IMEI that was in use on your number

How do you unblock the phone if you get it back?

Use the "Un-Block Found Mobile" option on the same portal. Enter your 18-digit Request ID, give a reason, verify the OTP and submit. The status updates once the un-blocking request is processed.

This is the whole reason to keep the Request ID safe. If you have mislaid it, the portal has a recovery option tied to the mobile number you registered. Recovered phones do turn up — sometimes weeks later, through a police recovery — so treat the block as reversible rather than final.

What should you do about UPI and bank apps on a stolen phone?

Treat this as the urgent part. Call your bank to block cards and net banking and to deactivate the UPI ID tied to that phone. If money has already gone, report it on the national cyber crime helpline 1930 or at cybercrime.gov.in — the sooner you report, the better the chance of a freeze.

A phone with a live SIM and unlocked banking apps is a payments device. The SIM block cuts the OTPs, but the apps themselves need separate attention, and the UPI ID registered against that device should be deactivated rather than merely left alone.

The helpline numbers are easy to confuse, so to be clear about which is which:

CEIR is one part of Sanchar Saathi, the Department of Telecommunications' citizen platform. The same platform has a module to report fraudulent calls and messages, and one to check the mobile connections registered against your own name — worth a look after an incident like this, in case a connection was taken out in your name.

Which law covers phone theft in India?

Theft is an offence under Section 303 of the Bharatiya Nyaya Sanhita 2023, and snatching — taking something suddenly or forcibly from a person — is a separate offence under Section 304. Buying or keeping a phone you know to be stolen is itself an offence under Section 317.

The BNS replaced the Indian Penal Code with effect from 1 July 2024, so the section numbers people remember from the old law no longer apply. A few points that matter in practice:

• Snatching is now its own offence. It was not separately defined in the old Code, and it covers exactly the common scenario of a phone taken from the hand or the pocket
• Buying a suspiciously cheap second-hand phone is a risk. Dishonestly receiving or retaining property you know or have reason to believe is stolen is an offence in its own right
• Tampering with an IMEI is a serious, separate offence. Under the Telecommunications Act 2023, altering a device's identification number can attract imprisonment of up to three years, a fine of up to ₹50 lakh, or both — and the offence is cognizable and non-bailable

That last point is the practical reason blocking works. Repairing a blocked handset by rewriting its IMEI is not a grey area; it is a criminal offence carrying a substantial penalty, which is what keeps most of the second-hand trade away from blocked devices.
