What is an IMEI number?

IMEI stands for International Mobile Equipment Identity. It is a unique 15-digit number assigned to every mobile device that identifies it on cellular networks. No two devices share the same IMEI.

How do I find my IMEI number?

The fastest way is to dial *#06# on your phone — the IMEI number will appear on screen. You can also find it in Settings > About Phone, printed on the device's original box, or under the battery on older phones.

Can I check if my phone is stolen using the IMEI?

Yes. You can check an IMEI against national blacklists using services like CEIR (in India) or GSMA Device Check. A blacklisted IMEI means the device has been reported stolen and may be blocked on networks.

Can an IMEI number be changed?

Changing an IMEI is illegal in most countries including India. The IMEI is stored in hardware (the baseband processor) and any modification is considered tampering with a government identifier.
