What is IMEI?

IMEI (International Mobile Equipment Identity) is a 15-digit identifier assigned to mobile devices.

What this validator checks

  • Length: IMEI must be exactly 15 digits
  • Format: only digits are allowed after removing spaces and hyphens
  • Checksum: the last digit must satisfy the Luhn algorithm
This tool validates format and checksum only. It does not verify blacklist status, activation, or ownership.

How to use

Enter a 15-digit IMEI. The validator automatically removes spaces and hyphens, checks the numeric format and Luhn check digit, and shows the normalized value and expected check digit.
