What Is an IMEI Number?
The IMEI is the 15-digit identity code of every phone. Learn how it works, what the digits mean, and how to use it safely when filing reports or checking devices.
IMEI definition and structure
IMEI stands for International Mobile Equipment Identity. The first eight digits identify the model and manufacturing batch, the next six digits are the unique serial number, and the last digit is a Luhn checksum that prevents typos. Manufacturers burn this code into the modem so it cannot be changed without tampering.
Where to find the IMEI
- Dial *#06# to display the 15-digit code on the screen.
- Inspect the retail box under the barcode.
- Remove the battery (if possible) and read the sticker inside the housing.
- Check the Settings > About Phone screen on recent Android and iOS devices.
Why the IMEI matters
The IMEI links a handset to warranty claims, carrier blocklists, and lost-phone alerts. When you report the IMEI to My Phone Finder, honest buyers can avoid suspicious listings and reach out if they find your device.
Use the IMEI safely
- Never pay for "instant GPS" services. Only carriers and police can request live location data.
- Share the IMEI only with recovery partners you trust to prevent phishing attempts.
- Register the IMEI with IMEI Tracker so our community can amplify your alert.
- Pair the data with Check IMEI to warn second-hand buyers.
Put the number to work
Store the 15 digits inside Phone Finder the moment a device disappears so neighbours and buyers see your alert. Before buying or selling, compare that same IMEI in Check IMEI and keep tabs on comments through the IMEI Tracker. Those three touchpoints turn a technical identifier into practical protection.
When a seller offers vague guarantees, point them to the authenticity checklist. It explains how IMEI transparency, paperwork, and hardware inspections work together so honest people can finalize deals confidently.
