IMEI Validator
An International Mobile Equipment Identity (IMEI) is a unique 15-digit number assigned to every mobile device. It is used by networks to identify valid devices and can be used to block stolen phones.
IMEI Structure
- TAC (Type Allocation Code, digits 1–8): Identifies the device model and manufacturer. Allocated by a reporting body such as GSMA BABT.
- Reporting Body (digits 1–2 of TAC): The certification body that allocated the TAC.
- Serial Number (digits 9–14): Unique serial number assigned by the manufacturer.
- Check Digit (digit 15): Computed using the Luhn algorithm.
Luhn Algorithm
The Luhn algorithm validates the check digit by doubling every second digit (from left), subtracting 9 if the result exceeds 9, then summing all digits. A valid IMEI produces a sum that is divisible by 10.
