IMEI Validator (International Mobile Equipment Identity)
Validate IMEIs by checking if they are mathematically correct using the Luhn algorithm.
How Does the IMEI Validator Work?
The IMEI Validator checks if a 15-digit number is mathematically valid using the Luhn algorithm. The validation process involves the following steps:
- Verifies that the IMEI has exactly 15 numeric digits.
- Separates the first 14 digits (TAC + SNR) from the last check digit.
- Applies the Luhn algorithm to the first 14 digits: doubles every second digit from right to left, subtracts 9 from values greater than 9, and sums all digits.
- Calculates the expected check digit and compares it with the provided one. For more information about IMEIs, see the Wikipedia documentation
