How to block a stolen phone in India
The Central Equipment Identity Register can bar a handset on every Indian network at once. The order of these steps matters — CEIR rejects any request that arrives without a police reference.
Find the IMEI before you do anything else
You need the 15-digit IMEI of the stolen handset. If you still have the box, it is printed on the barcode label. Otherwise check your Google or Apple account — both record the IMEI of every device you signed into.
A dual-SIM phone has two IMEIs. Write down both.
If you can no longer retrieve the IMEI, the CEIR request cannot proceed. There is no lookup by phone number.
- Find a device IMEI in your Google account Devices → select the handset → details
File a police complaint
CEIR will not accept a blocking request without a police complaint number. Most state police forces accept an online FIR or e-complaint for lost property, so you usually do not need to attend a station.
Keep the PDF — you will upload it in step four.
- Find your state police e-FIR portal CEIR links the correct portal per state
Get a working alternate number
CEIR sends a one-time password to an alternate mobile number, and that number becomes the contact point for the request. It must be a number you control and will keep — you need it again to unblock the device if it is recovered.
Submit the block request
Go to the CEIR portal and open the block request form. You will need the IMEI (both, if dual-SIM), the lost mobile number, the handset make and model, the date and place of loss, the police complaint copy, and an identity document.

Verify with the OTP and save the request ID
Confirm the OTP sent to your alternate number. The portal then issues a request ID.
Save it. It is the only way to check status later, and the only way to unblock the handset if you get it back.
Losing the request ID means starting the entire process again, including a fresh police reference.
Wait for propagation
The block fans out from CEIR to every operator's own Equipment Identity Register. In practice this completes within about 24 hours, often much sooner. Until it lands the handset still works normally.
Secure the accounts, separately
Barring the IMEI stops the handset using a mobile network. It does not wipe it, does not stop it working on Wi-Fi, and does not protect anything stored on it.
Change the passwords for every account that was signed in, revoke the device's sessions, and issue a remote wipe if the platform supports one. Treat the block as an anti-resale measure, not a privacy control.
Unblock it if the phone comes back
Use the same portal and the request ID from step five. You will repeat identity verification and confirm another OTP. Unblocking is deliberately not instant.
Do not simply insert a SIM and expect it to work — the handset will keep being refused until the register is updated.
Problems
The portal rejects my IMEI as invalid
Most rejections are transcription errors rather than genuine problems. Run the number through our IMEI Checker first — it validates the Luhn check digit, which catches a single mistyped or transposed digit immediately.
I only blocked one IMEI on a dual-SIM phone
Submit a second request for the other IMEI. Blocking one radio leaves the other fully usable, and this is the single most common self-inflicted failure in the whole process.
The handset is still working after 48 hours
Check the request status with your request ID first. If it shows completed and the device is still attaching, the IMEI may have been reprogrammed — which is illegal, but does happen. Report that back through the police complaint.
FAQ
Does blocking the IMEI delete my data?
No. It stops the handset registering on a mobile network. The device still powers on, still holds its contents, and still works over Wi-Fi. Data protection is a separate job — see step seven.
Does the block work outside India?
No. CEIR covers Indian operators. A barred handset will attach normally on a foreign network, which is exactly why stolen devices are moved across borders. There is no global blacklist that every country honours.
Can I check an IMEI before buying a used phone?
Yes, and you should. The Know Your Mobile lookup on the CEIR site reports whether an IMEI is blocked, duplicated or otherwise suspect. It takes about ten seconds and it is the cheapest fraud check available in the Indian market.
Is there any cost?
No. Both blocking and unblocking through CEIR are free. Any site charging for this service is reselling something you can do yourself.
