🇮🇳 Filing a Mobile Lost Complaint Online in India
If your smartphone is lost or stolen in India, the country has specific systems in place to help you recover your device or prevent its misuse.
📊 Using the CEIR Portal
The Central Equipment Identity Register (CEIR) is a government initiative in India that allows citizens to report and track lost or stolen mobile phones. This system blocks the IMEI number of the device, making it unusable even if the SIM card is changed.
To file a complaint on CEIR:
- Visit the official CEIR website
- Register using your phone number and email
- File a police complaint first and get an FIR number
- Submit the FIR details along with your device’s IMEI number on the portal
- Track the status of your complaint through the portal
👮 Filing a Police Complaint
Before using the CEIR portal, you must file an official police complaint:
- Visit the nearest police station
- Provide your device details (IMEI number, model, color)
- Describe when and where you last had your phone
- Get an acknowledgment or FIR copy for your records
Alternatively, you can file an online police complaint through the Digital Police Portal in many Indian states, which saves time and provides immediate documentation.
