Have you lost your mobile phone? Do not worry. The CEIR Portal can help you block it.
CEIR (Central Equipment Identity Register) is a national database managed by the Department of Telecommunications (DoT) under the Ministry of Communications to curb device theft and secure mobile networks in India. To stop a stolen phone from working, CEIR adds the device’s unique 15-digit IMEI number to a central blacklist shared across all telecom operators, rendering the handset completely unusable for calls, SMS, or mobile data across any Indian network even if the SIM card is replaced. Citizens can block and trace lost or stolen mobile phones by submitting a request on the official Sanchar Saathi portal at ceir.gov.in with a police report, identity proof, and a duplicate SIM for OTP verification.

What Is the CEIR Portal?
CEIR is a government system for mobile phones.
Every mobile phone has a special number. This number is called the IMEI number. CEIR uses this number to identify phones.
If someone steals your phone, you can request a block. This stops the phone from using Indian mobile networks.
The thief may insert another SIM card. However, the blocked phone should still remain blocked on supported networks.
The government developed this service to help people to reduce the use of stolen phones.

How CEIR Works: The Role of the IMEI Number
IMEI means International Mobile Equipment Identity. It is a special number for your mobile phone.
Think of it as your phone’s identity number. Mobile networks use it to identify the phone.
Your phone usually has a 15-digit IMEI number. Phones with two SIM slots may have two numbers.
How to Find Your IMEI Number
Follow these easy steps:
- Open your phone’s calling screen.
- Type *#06# where you type phone numbers.Â
- Your IMEI number will appear on the screen.
- Write it down and keep it safe.
You may also find it on the phone box. Sometimes, it appears on your purchase bill.
How Does Blocking Work?
Suppose someone steals your phone. You report the theft and request blocking.
CEIR uses your phone’s IMEI number. It then asks mobile networks to block that phone.
The phone should not work on supported Indian networks. Changing the SIM card does not remove the block.
