IMEI validator & analyzer
Check whether an IMEI is genuine-looking or mistyped. We verify its length and Luhn checksum and break it into its parts: TAC, serial number and check digit.
How it works

- 02See instantly whether it is valid.
- 03Review the breakdown of each part.
What makes an IMEI valid
A valid IMEI has 15 digits and its last digit matches the Luhn checksum of the first 14. A 16-digit IMEISV has no check digit; its last two digits are the software version.
Valid doesn't mean clean
A valid IMEI can still be blacklisted, locked or cloned. To check the phone's status, get a safety report.
Anatomy of an IMEI
Every IMEI has the same 15-digit structure. Each part tells you something different.
Type Allocation Code. Identifies the manufacturer and exact model. The first two digits are the reporting body.
Unique number the manufacturer assigns to this single device.
Calculated from the other 14 with the Luhn formula. Catches typos.
Frequently asked questions
Why is my IMEI invalid?
Most often it's a typo. Re-read the number from *#06#. If it still fails, the IMEI may have been tampered with.
What is the TAC?
The first 8 digits, the Type Allocation Code, identify the manufacturer and model.
What is IMEISV?
A 16-digit variant that replaces the check digit with a 2-digit software version number.
