IMEI Generator and Validator

Use this IMEI generator and validator for safe testing and learning. It creates sample IMEI numbers and checks any 15 digit IMEI you enter. It uses the Luhn checksum to confirm that the number is valid.

Disclaimer

Use this tool for development and testing and education only. Using fake IMEI numbers on real devices or for fraud is illegal. Follow local laws and company policies at all times.

What is an IMEI

IMEI stands for International Mobile Equipment Identity. An IMEI is a unique 15 digit number that identifies a mobile device. Each IMEI includes three parts.

• Type Allocation Code has 8 digits and marks the device model.
• Serial number has 6 digits and marks the device unit.
• Check digit has 1 digit and verifies the number with the Luhn method.

The Luhn algorithm is a checksum method used to catch entry errors.

How this IMEI generator works

The generator builds a test IMEI in three steps.

1. It picks a sample Type Allocation Code from a small preset list.
2. It creates a random 6 digit serial number.
3. It computes the final check digit with the Luhn method.

The result matches IMEI format rules and passes checksum checks.

How to use this tool

Generate a test IMEI

1. Click Generate Random IMEI.
2. Read the value shown under Generated IMEI.
3. Check the TAC and Serial and Check digit details if you need them.
4. Copy the number and paste it into your test.

Validate an IMEI

1. Enter a 15 digit IMEI in the input box.
2. You can include spaces or dashes. The tool ignores them.
3. Click Validate or press Enter.
4. Read the result message with the formatted IMEI and details.

Inputs and outputs

Inputs

• Generator uses no input fields.
• Validator uses one text field for a 15 digit IMEI.
• The field accepts digits and spaces and dashes.

Outputs

• Generator shows the IMEI in five blocks of three digits.
• It lists TAC and Serial and Check digit.
• Validator shows status as Valid IMEI or Invalid IMEI.
• If valid it shows TAC and Serial and a verified check digit.
• If invalid it shows the provided and expected check digit.
• It shows the corrected IMEI built from your first 14 digits.

How to read the results

• Invalid format means the input length differs from 15 digits.
• Valid IMEI means the number passes the Luhn checksum rule.
• Invalid IMEI means the check digit differs from the expected value.
• Correct IMEI shows the same first 14 digits and the right check digit.

Why use this IMEI generator

• It saves time during tests and demos.
• It reduces input mistakes with ready made valid numbers.
• It helps teach checksum logic with clear parts and a checked digit.

Common use cases

• Mobile app screens that capture IMEI during signup or support.
• Backend services that need IMEI validation tests.
• Quality checks for form rules in web or desktop apps.
• Class demos on checksum math and data validation.
• Seed data for testing and staging databases.

Limitations and notes

• Generated numbers exist for tests and training.
• The generator uses a small set of sample Type Allocation Code prefixes.
• Validation checks length and the Luhn rule only.
• It skips device status and model lookups and carrier checks.
• Checks run on this page with local logic.
• Use real IMEI values only for lawful service work and device support.
• To view your phone IMEI dial star hash zero six hash.

Tips for accurate results

• Use this tool in a lab or staging setup.
• Label generated numbers as test in your data.
• Click generate again for a fresh IMEI.
• Strip spaces and dashes before storing an IMEI in a database.

FAQ

Is an IMEI the same as a serial number

An IMEI identifies the device for networks. A device serial tracks manufacturing and support events. They serve different jobs.

What is the Luhn algorithm

The Luhn algorithm is a checksum method used to catch entry errors. It doubles every second digit from the right. It then adds all digits and checks the total.

Can I paste numbers with spaces or dashes

The validator accepts spaces and dashes during input.
