IMEI generator

Generate structurally valid, Luhn-algorithm-checked IMEI numbers for mobile device testing, QA workflows, and database seeding. All numbers use real TAC prefixes from major manufacturers — never real device IMEIs.

What is an IMEI number?

IMEI stands for International Mobile Equipment Identity. It is a unique 15-digit number assigned to every mobile phone, smartphone, and some satellite devices. IMEIs are used by carriers to identify devices on their networks, block stolen handsets, and manage device policies in Mobile Device Management (MDM) systems.

How does this IMEI generator work?

Each generated IMEI is built from two parts: a real TAC (Type Allocation Code) prefix from a major manufacturer, and a random serial number. The final digit is computed using the Luhn algorithm — the same checksum formula used to validate credit card numbers — ensuring every generated IMEI passes structural validation.

TAC prefixes used

Common uses for generated IMEI numbers

Developers use fake IMEIs to test mobile applications that require IMEI-based device identification without exposing real user devices. QA engineers use them to populate test databases, validate input fields, and test telecom billing systems. MDM platform developers use bulk-generated IMEIs to simulate device fleets during development.

API access

The IMEI generator is also available via the Toolpad REST API. Use GET /api/v1/network/imei?count=10 to generate up to 100 IMEIs programmatically.

Frequently asked questions

Are generated IMEIs real? +
No. Generated IMEIs are structurally valid (they pass Luhn checksum validation and use real TAC prefixes) but are not registered to any physical device. They will not work on real mobile networks.
Is it legal to use generated IMEI numbers? +
Yes, for legitimate software development and testing purposes. It is illegal to use a generated IMEI to misrepresent a device on a mobile network, clone a device, or bypass security measures. This tool is intended for developers only.
What is the Luhn algorithm? +
The Luhn algorithm (also called mod-10) is a simple checksum formula used to validate identification numbers. It works by doubling every second digit from the right, summing all digits, and checking that the total is divisible by 10. IMEI numbers, credit card numbers, and several other ID types use this algorithm.
