Random IMEI Generator for Testing

This random IMEI generator creates valid test numbers for software projects. It uses the Luhn algorithm to add a correct check digit. You can copy each result and reuse it in your test cases.

Important disclaimer

Use this tool for software testing and development only. These are fake IMEI numbers for safe lab use. They do not identify any real device on a network. Using fake identifiers on real networks may break local laws. Follow all rules in your area and your company policy.

What is an IMEI

IMEI means International Mobile Equipment Identity. It is a 15 digit number. Many systems use it to track devices on cellular networks. It acts as a unique device identifier during network checks.

• The first 8 digits form the Type Allocation Code, short form TAC.
• The next 6 digits form the device serial number.
• The last digit is a check digit from the Luhn algorithm.

What this random IMEI generator does

• Creates a 15 digit IMEI for test use.
• Builds a valid Luhn check digit every time.
• Shows a clear Valid or Invalid status for the output.
• Presents the number in four groups separated by dashes for easy reading.
• Uses common TAC prefixes to mirror real formats.
• Generates numbers that are random and not tied to real devices.

How to use this tool

1. Select the Generate Test IMEI button.
2. Read the value under Generated Test IMEI.
3. Check the Validation Status line for Valid.
4. Press Copy to Clipboard to copy the number.
5. Choose Generate Another to create a fresh value.

That is all you need for quick test data. Keep the copied value in your notes or scripts.

Inputs and controls

• This tool needs no input fields from you.
• Generate Test IMEI creates a new test IMEI.
• Copy to Clipboard copies the displayed value with the same format.
• Generate Another repeats the process and shows a new IMEI.

Understanding the output

• Generated Test IMEI shows a 15 digit number split into four groups. The format uses separators for readability.
• Validation Status displays Valid for a correct Luhn result.
• Details explains that the number passed the Luhn algorithm check.
• The grouping follows this pattern. Six digits, two digits, six digits, one digit.

About IMEI numbers

• IMEI length is 15 digits in total.
• The structure is 8 digit TAC, 6 digit serial, and 1 check digit.
• The Luhn algorithm computes the final check digit.
• Real IMEIs identify hardware on cellular networks.
• Generated values here serve as test data only.

Common use cases

• Form validation during quality assurance checks.
• Unit tests that need valid IMEI input.
• Database seeding for staging builds.
• API mocks and contract tests.
• Demo content for screenshots and user guides.
• Training material for test teams.

Tips for clean testing

• Store the IMEI as text to avoid dropping leading zeros.
• Remove separators if your system expects digits only.
• Keep the length at 15 digits for every test.
• Log the source of your test IMEIs for traceability.
• Use a fresh IMEI for each test case to avoid overlap.

How the Luhn check works, in brief

• Starting from the right, double every second digit.
• If a doubled digit is greater than nine, subtract nine.
• Add all digits, then find the total modulo ten.
• The check digit makes the total end at zero.

Limitations and notes

• The generator creates fake data for safe lab use.
• It validates only the numbers it creates.
• It does not check device brand, model, or carrier records.
• It does not guarantee a new number never repeats.
• The copy feature depends on your browser settings.
• Local laws govern the use of test identifiers on networks.

Get the most value

• Use this random imei generator to speed up test setup.
• Keep a small library of valid IMEIs for repeatable tests.
• Document which test used which IMEI in your tickets.
• Share sample IMEIs with your team to keep tests aligned.

Quick answers

• Can I use these on real devices Use them only in test systems.
• Do the numbers pass a Luhn check Yes, the check digit is correct.
• Can I remove separators Yes, most systems accept plain digits.
• Does it accept my own IMEI No, the tool only generates and validates its own output.

Respect legal rules at all times. This keeps your testing safe and clean.
