What Is an IMEI Generator?
An IMEI (International Mobile Equipment Identity) is a 15-digit number that uniquely identifies a mobile device on cellular networks. The final digit is a check digit calculated using the Luhn algorithm — the same checksum method used on credit card numbers. Software testers, app developers, and QA engineers often need valid-format IMEI strings when building registration flows, device management screens, and telecom integrations without using real hardware identifiers.
Our free IMEI Generator at Tools Galaxio produces 15-digit numbers with a mathematically correct Luhn check digit. Generate one IMEI or bulk batches for test datasets — free, instant, and browser-based.
Key Features of Our IMEI Generator
1. Valid 15-Digit Format
Every generated IMEI contains exactly 15 numeric digits, matching the standard structure used by GSM and LTE device identification systems.
2. Luhn Check Digit
The final digit is computed with the Luhn algorithm so the number passes basic checksum validation used by many forms and APIs.
3. Bulk Generation
Create multiple IMEI numbers in one run for populating test databases, CSV imports, and automated QA scripts.
4. Copy-Ready Output
Copy individual IMEIs or the full list to your clipboard with one click.
5. Free for Development & QA
No API key, no subscription, and no account required. Open the page and generate test identifiers on demand.
6. Privacy-Safe Testing Data
Use fictional IMEIs instead of real device identifiers to protect user privacy during development and staging.
How to Use the IMEI Generator — Step by Step
Step 1 — Set the Quantity
Choose how many IMEI numbers you need — a single value for a form test or a larger batch for database seeding.
Step 2 — Generate IMEIs
Click generate to produce random 15-digit numbers with valid Luhn check digits.
Step 3 — Verify Format
Confirm each output is 15 digits long and numeric only, matching your application's input validation rules.
Step 4 — Copy the Results
Copy the generated IMEIs to your clipboard for pasting into spreadsheets, JSON fixtures, or test forms.
Step 5 — Import Into Your Test Environment
Use the numbers in staging databases, mock API responses, or UI screenshots as placeholder device data.
Step 6 — Regenerate as Needed
Create fresh batches whenever you need new test identifiers. Each generation is independent.

Frequently Asked Questions
What is an IMEI number?
An IMEI is a 15-digit identifier assigned to mobile devices for use on cellular networks. It helps carriers and manufacturers distinguish one handset from another.
What is the Luhn check digit?
The Luhn algorithm produces a validation digit from the preceding numbers. A correct check digit means the IMEI passes standard checksum validation, which many software forms require.
Are generated IMEIs tied to real phones?
No. These are randomly generated test values. They are not registered to real devices and must only be used in development, QA, and demonstration contexts.
Can I use fake IMEIs in production?
No. Production systems should use real device identifiers obtained through proper channels. This tool is intended for testing and staging environments only.
Is the IMEI generator free?
Yes, completely free with no signup. Generate as many test IMEIs as your project requires.
How many IMEIs can I generate at once?
You can request bulk batches in a single run. Enter the quantity you need and copy the full list from the output.
Will these pass Luhn validation in my app?
Yes. Each generated IMEI includes a correctly calculated Luhn check digit, so forms and APIs that validate checksums should accept the format.
Are generated IMEIs stored on your servers?
No. Generation happens locally in your browser. Nothing is uploaded or saved by Tools Galaxio.
