IMEI - Explained !

(International Mobile Equipment Identity)

The IMEI is a 15-digit unique code that identifies a mobile device, acting like its “fingerprint.” Here’s everything you need to know:


Structure of an IMEI

  1. TAC (Type Allocation Code, 8 digits) – Identifies the manufacturer and model.
  2. SNR (Serial Number, 6 digits) – Unique to each device.
  3. Check Digit (1 digit) – Validates the IMEI using the Luhn algorithm.

Example: 35-123456-789012-3 (without hyphens)


What is the IMEI Used For?

✔ Device Identification – Carriers use it to block stolen phones.
✔ Warranty Verification – Manufacturers check warranty status via IMEI.
✔ Anti-Theft Tracking – Helps track lost or stolen devices.
✔ Network Authentication – Some carriers require IMEI registration.


How to Find Your IMEI

  1. Dial *#06# – Instantly displays the IMEI on most phones.
  2. Check Device Settings:
    • AndroidSettings → About Phone → Status
