Mobile phone theft is a prevalent issue that can lead to significant privacy breaches and financial losses. Taking immediate action is crucial to protect your personal information and prevent unauthorized use of your device. In this article, we will provide a step-by-step guide on how to block a stolen mobile phone using CEIR (Central Equipment Identity Register), as well as answer common questions related to this topic.

How to Block Stolen Mobile Phone: Role of CEIR and IMEI

CEIR, also known as the Central Equipment Identity Register, is a centralized database that stores information about mobile devices. It is used to combat mobile phone theft and helps in blocking stolen devices. The IMEI (International Mobile Equipment Identity) number is a unique identifier assigned to each mobile phone. This number plays a vital role in identifying stolen devices and blocking them.

How Can I Block My Lost Phone with IMEI Mumber?

Yes, you can block your lost phone using the IMEI number. Here’s how:

Inform the nearest police

Report the theft to your nearest police immediately. Provide them with all relevant details about your missing mobile device, including the IMEI number, make and model of your phone, and any other identifiable information. This information will aid in their investigation.

Inform your service provider

Get in touch with your mobile service provider like Samsung, Apple, etc. and inform them about the theft. They will be able to block your missing device using the IMEI number, rendering it useless on their network and preventing unauthorized usage.

How to Block a Mobile Phone if it is Stolen?

Repot to nearest police station

As mentioned earlier, reporting the theft to the police is crucial. They will create a report and document the details of the incident. This information will aid in their investigation.

Contact your service provider

Reach out to your service provider’s customer support immediately. Provide them with the necessary information, including the IMEI number, to block your stolen phone. They will ensure that your device is blacklisted in their system, making it inoperable on their network.

Activate remote tracking or wiping features

Some mobile phone manufacturers and security apps offer remote tracking and data wiping features. If you have enabled such features on your phone before it got stolen, you can use them to track the device’s location or remotely wipe the data to protect your personal information.

Here are the steps to block a stolen or lost mobile phone through the CEIR website:

  1. Visit the CEIR website by going to https://www.ceir.gov.in/Home/.
  2. Then, click on the “Block Stolen / Lost Mobile” button or directly visit https://www.ceir.gov.in/Request/CeirUserBlockRequestDirect.jsp.
  3. Provide the necessary information in the Device Information, Lost Information, and Mobile Owner Personal Information sections.
  4. Then, click on the “Submit” button.
  5. Upon submission, you will receive a request ID, which you can use for further tracking.

Once the request is registered, the mobile phone will be blocked within 24 hours, making it unusable on any network.

  • Check Request Status: CEIR allows you to check the status of your request for blocking a lost or stolen mobile phone. Simply access the CEIR portal and track the progress of your request using the provided request ID.
  • KYM (Know Your Mobile): Before purchasing a mobile phone, you can ensure its validity and status through KYM. This can be done using SMS, the KYM App, or the CEIR web portal. By performing a KYM check, you can verify important details about the device, such as its authenticity and any reported incidents.

Can a Mobile Be Tracked with IMEI Number?

While the IMEI number is an essential identifier for blocking stolen devices, it has limitations when it comes to tracking a mobile phone’s location. However, several tracking apps and services utilize GPS or other technologies to track a stolen device more accurately. It’s essential to enable tracking features on your phone before it gets stolen to increase the chances of successful recovery.

Can Police Track IMEI if the Phone is Off?

Tracking a stolen phone solely based on the IMEI number is not possible if the device is turned off. The IMEI number alone does not transmit any location information. However, providing the IMEI number to the police is still crucial as it assists in their investigation and increases the likelihood of recovering the stolen device.


In the unfortunate event of a stolen mobile phone, taking immediate action is crucial. By reporting the theft to the police, contacting your service provider, and providing them with the IMEI number, you can effectively block your stolen device. Additionally, enabling remote tracking and wiping features on your phone beforehand can aid in recovery and protect your personal data. Remember to stay vigilant and take preventive measures to minimize the risk of mobile phone theft, such as installing security apps and enabling tracking features. By following these steps, you can protect yourself from the consequences of a stolen mobile phone and safeguard your privacy and information.
