Random IMEI Generator
Generate valid random IMEI numbers instantly. Every number passes the Luhn checksum algorithm. Choose your format, generate a single number or a batch of up to 100, and copy in one click.
For testing and educational use only. These are randomly generated numbers that satisfy the Luhn checksum. They are not tied to any real device, manufacturer, or network. Do not use them to misrepresent device identity or bypass any system.

Verify an IMEI Number
Enter any 15-digit IMEI to check whether its Luhn checksum is valid.
What is an IMEI number?
An IMEI (International Mobile Equipment Identity) is a unique 15-digit number assigned to every mobile device. It is used by mobile networks to identify valid devices and can be used to block a stolen phone from accessing the network. Every phone, tablet, and cellular-enabled device has at least one IMEI. You can find your device's IMEI by dialing *#06# or checking Settings > About.
How an IMEI Number is Structured
An IMEI is exactly 15 digits long and is divided into three components:
| Segment | Digits | Purpose |
|---|---|---|
| TAC (Type Allocation Code) | 1–8 | Identifies the device model and manufacturer. Assigned by the GSMA. |
| SNR (Serial Number) | 9–14 | A unique serial number for the specific device within its TAC group. |
| Check Digit | 15 | Calculated using the Luhn algorithm to validate the preceding 14 digits. |
The IMEIs generated by this tool have randomized TAC and SNR segments and a correctly calculated Luhn check digit. They are structurally valid but are not registered to any real manufacturer or device.
What is the Luhn Algorithm?
The Luhn algorithm (also known as the “modulus 10” or “mod 10” algorithm) is a simple checksum formula used to validate identification numbers. It was created by IBM scientist Hans Peter Luhn in 1954. Beyond IMEI numbers, it is also used to validate credit card numbers, Canadian Social Insurance Numbers, and various other ID systems.
Take the first 14 digits of the IMEI.
Starting from the second digit (index 1), double every other digit moving left to right.
If any doubled digit is greater than 9, subtract 9 from it.
Sum all 14 digits (with the doubled values applied).
The check digit is (10 − (sum mod 10)) mod 10. If the sum is already a multiple of 10, the check digit is 0.
Who Uses a Random IMEI Generator?
Mobile App Developers
Populate device identifier fields in test environments and staging databases. Avoids using real device data during development and QA cycles.
QA Testers
Generate batches of valid IMEI numbers to test device registration flows, input validation, and form handling in mobile or telecom applications.
Database Administrators
Seed development and test databases with realistic, structurally valid IMEI data without using production device identifiers.
Telecom & IoT Developers
Test device management systems, SIM provisioning workflows, and network registration logic with valid but non-production IMEI numbers.
Security Researchers
Test IMEI validation logic, input sanitization, and identifier handling in mobile security tools and penetration testing scenarios.
Students & Learners
Understand how the Luhn checksum works, practice implementing validation algorithms, and learn about mobile device identification standards.

Frequently Asked Questions
Are the generated IMEIs real?
No. The numbers are randomly generated and are not registered to any manufacturer, network, or real device. They are structurally valid — every number passes the Luhn checksum — but the TAC segment does not correspond to a real device model. They are suitable for testing and development only.
What does 'passes the Luhn algorithm' mean?
It means the 15th digit (check digit) is correctly calculated from the first 14 digits using the Luhn checksum formula. Any system that validates IMEI format will accept these numbers as structurally correct. It does not mean the IMEI is registered on any network or belongs to a real device.
Can I use these IMEIs in my app or database?
Yes, for testing and development environments. They are valid for populating test databases, seeding dummy data, and testing form validation logic. Do not use them in production systems or to misrepresent any real device.
What formats are available?
Plain (15 consecutive digits), Grouped (8-6-1 with spaces, matching the TAC-SNR-Check structure), Hyphenated (8-6-1 with hyphens), and Spaced (each digit separated by a space). All formats contain the same underlying 15-digit number.
How do I verify an IMEI?
Use the Verify section on this page. Enter any 15-digit IMEI and the tool will calculate whether its check digit matches the Luhn formula. This checks structural validity only — it does not check whether the IMEI is registered on any network.
Is it illegal to generate fake IMEI numbers?
Generating random IMEI numbers for testing and educational purposes is legal. Using a fake IMEI to misrepresent a device, bypass network restrictions, or commit fraud is illegal in most countries. This tool is intended for developers, testers, and learners only.
