Sample IMEI Generator

About Sample IMEI Generator

The Sample IMEI Generator creates valid-format 15-digit International Mobile Equipment Identity (IMEI) numbers for testing and development use. Each generated IMEI has a valid Luhn algorithm check digit in the 15th position, ensuring it passes standard IMEI format validation. The tool also optionally generates IMEI-SV (IMEI with Software Version, 16 digits) for devices that require it. You can select a TAC prefix (Type Allocation Code, the first 8 digits identifying manufacturer/model) from a set of common manufacturer codes, or generate with a random TAC. These sample IMEIs are suitable for testing mobile device management (MDM) software, carrier systems, inventory systems, and any application that validates IMEI format.

Why use Sample IMEI Generator

• Generates IMEIs with correct 15-digit format and Luhn check digit.
• Supports IMEI-SV (16-digit) format as well.
• Optional TAC prefix selection for manufacturer-specific test data.
• Bulk generation for database and API testing.
• Every generated IMEI has a valid Luhn check digit — passes any compliant 15-digit IMEI validator.
• Optional IMEI-SV (16-digit) format for testing 3G/4G/5G provisioning systems that use it.

How to use Sample IMEI Generator

1. Click Generate to create a sample IMEI with a valid Luhn check digit.
2. Optionally select a manufacturer TAC prefix.
3. Toggle IMEI-SV format for 16-digit output.
4. Use Bulk mode to generate multiple IMEIs for test seeding.
5. Click Generate to create a sample IMEI with a valid 15-digit format and Luhn check digit.
6. Optionally select a manufacturer (Apple, Samsung, Xiaomi, etc.) to use a realistic 8-digit TAC prefix.
7. Toggle IMEI-SV format for a 16-digit output that replaces the check digit with a 2-digit Software Version Number.

When to use Sample IMEI Generator

• Testing IMEI validation in mobile device management or carrier software.
• Seeding device inventory databases with IMEI fields.
• Generating mock device data for development and demo environments.
• Unit testing Luhn algorithm implementations.
• Testing IMEI validation in mobile device management (MDM), carrier provisioning, or inventory software.
• Seeding device databases for staging environments with realistic-looking IMEI columns.

Examples

Tips

• Always store generated IMEIs in a clearly named fixture (e.g. tests/fixtures/sample-imeis.csv) so they never get treated as real devices.
• If your validator rejects a generated IMEI, confirm it uses Luhn (mod 10) — some custom validators check additional rules like a real-TAC lookup which the sample data won't match.
• Pair sample IMEIs with sample MEID or ICCID values when your test flow needs more than one device identifier.
• Never submit a generated IMEI to a carrier, GSMA, or device-locating service — that is fraudulent and traceable.
• When fuzz-testing, mix valid IMEIs with deliberately broken ones (14-digit, alphanumeric, bad checksum) to verify error handling paths.
• For device-tracking or anti-theft tests, prefer tagging your sample IMEIs in the database with a TEST_ prefix on the device name to prevent accidental real-world use.
• Use IMEI-SV mode for 3G/4G provisioning tests — older systems using just 15-digit IMEI may differ in validation logic.

Glossary

IMEI

International Mobile Equipment Identity — a 15-digit number that uniquely identifies a mobile phone or cellular-equipped device, used by carriers to authorize devices on their networks.

Luhn algorithm (mod 10)

A simple checksum formula that detects single-digit errors and most transpositions. Each digit is doubled or kept on alternation, doubled values >9 have their digits summed, the total is summed, and the check digit is chosen so the grand total is divisible by 10.

TAC

Type Allocation Code — the first 8 digits of an IMEI. It identifies the manufacturer and exact model of the device. TACs are issued by the GSMA from a central registry.

IMEI-SV

IMEI with Software Version — a 16-digit variant used in 3G/4G/5G networks. The 15th and 16th digits are the Software Version Number (SVN); there is no Luhn check digit.

GSMA

Global System for Mobile Communications Association — the international trade body for mobile carriers that maintains the official TAC registry and IMEI allocation scheme.

Serial number (IMEI)

Digits 9-14 of an IMEI — a 6-digit serial number assigned by the manufacturer to uniquely identify each device within a TAC.

MEID

Mobile Equipment Identifier — a 14-character hexadecimal alternative to IMEI used by some CDMA networks; superseded by IMEI on most modern devices.

Check digit (IMEI)

The 15th digit of a standard IMEI, computed from the first 14 digits using the Luhn algorithm. It detects most data-entry errors.
