What Is CEIR?

To tackle the counterfeit mobile phone market and discourage mobile phone theft, protect consumer interest, and facilitate law enforcement authorities for lawful interception. The Department of Telecom (DoT) has implemented the Central Equipment Identity Registry (CEIR) that connects to the IMEI database of all mobile Operators.

This Government portal works in collaboration with Telecom operators and device manufacturers to make a list of IMEI databases of stolen and found devices. All the devices listed in the database will be locked and blacklisted by all telecom operators, and the thief will not be able to use them anymore. The portal also allows unblocking the device once found.

Before proceeding to report a complaint to block your lost or stolen phone on the CEIR portal, here are the documents you must have:


  • Bill or Invoice of Purchase

How to Check if a Phone Is Lost / Stolen While Buying

The CEIR portal also allows fetching data from its portal, and checking whether the second-hand or refurbished phone you are going to buy is a stolen phone or not. It can be done in three ways, with the help of the IMEI number of the phone you are willing to purchase:

SMS Verification

The first way to check the lost status of a secondhand phone is to note down its IMEI number, by dialing *#06#, and send the following message from your phone.

Type KYM <15 digit IMEI number> and send it to 14422

App Verification

If the SMS verification is taking much longer to get the status, you can use the KYM app on Android and iOS. Here’s how to use it.

1. Download the KYM – Know Your Mobile App (Android, iOS) on your phone.

2. Allow required permissions to the app.

3. Once on the home page of the app, type the IMEI number of the phone you are willing to purchase, or you can directly scan its barcode from the app.

4. Tap on verify to get the details of the phone, and check for any lost or stolen status of it.

Web Verification

The KYM does not mention anything if the IMEI number is not reported for any lost/theft compliant. For a better idea, you can also visit the CEIR portal’s online tool, to check the status of the second hand mobile phone.

1. Visit the CEIR phone status verification online tool, and enter your phone number for OTP verification.

2. Now, enter the IMEI number of the phone you are willing to purchase, and click the Check button.

3. If you see IMEI as Valid, then it means the status is clean, and you can proceed to purchase it. A blocked or invalid tag means the phone is reported as stolen or lost, and you should not buy it.

If the status comes clean, proceed to check other elements, to make sure you buy a perfect phone. Check out our guide on things to check while buying a second-hand phone.
