How it works
- 01Choose how many IMEIs you need.
- 02Optionally enter a TAC prefix to generate numbers for a specific model range.
- 03Copy the list or download it as TXT, CSV or JSON.
How generated IMEIs are built
Each number is 14 random digits plus a check digit calculated with the Luhn algorithm, so it passes the same validation real IMEIs do. Without a prefix we use the 00 range, which is reserved for test equipment.
Only for testing
Generated IMEIs belong to no real phone. Changing a phone's IMEI is illegal in many countries, including the UK and India. Use these numbers only in test data.
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
Are generated IMEIs real?
No. They are mathematically valid but random, and not assigned to any device.
Can I generate an IMEI for a specific phone model?
Enter the model's 8-digit TAC as the prefix. You can find TACs with our TAC lookup tool.
Is there a limit?
You can generate up to 1,000 IMEIs per batch, as many times as you like.
