Overview

The IMEI Generator is a utility designed to generate valid International Mobile Equipment Identity (IMEI) numbers for mobile devices. It calculates the correct Luhn checksum for every generated number, allowing you to specify a custom Type Allocation Code (TAC) prefix and output up to 100 valid IMEIs instantly.

When to use

When testing mobile application workflows or database schemas that require valid 15-digit IMEI formats.
When simulating device registration, inventory management, or telecom billing systems without using real hardware identifiers.
When verifying Luhn algorithm validation logic in software development environments.

How it works

1Enter the desired quantity of IMEI numbers to generate, up to a maximum of 100.
2Optionally input a Type Allocation Code (TAC) prefix of 1 to 14 digits to target specific device models or manufacturers.
3The tool automatically pads shorter prefixes, calculates the final 15th digit using the Luhn checksum algorithm, and outputs the valid IMEI list.

Use cases

Populating test databases with realistic mobile device identifiers for QA testing.
Validating input field validation rules and error handling for IMEI entry forms.
Simulating bulk device provisioning and enrollment in Mobile Device Management (MDM) platforms.

Examples

1. Bulk Test Data Generation for MDM Software

QA Engineer

Background

A software tester needs to verify that a new Mobile Device Management platform can import and parse a batch of 50 mobile devices.

Problem

The tester needs 50 unique, syntactically valid IMEI numbers to populate the import CSV template.

How to use

Set the quantity to 50, leave the TAC prefix blank, and click generate.

{
  "quantity": 50
}

Outcome

The tool outputs a list of 50 unique 15-digit IMEI numbers, all passing the Luhn checksum validation.

2. Simulating Specific Device Models

Telecom Systems Analyst

Background

An analyst is testing a billing system that routes traffic differently based on the device's Type Allocation Code (TAC).

Problem

The analyst needs to generate test IMEIs that specifically start with the TAC prefix '49015420' to simulate a specific phone model.

How to use

Enter '49015420' in the TAC Prefix field, set the quantity to 5, and generate the numbers.

FAQ

Are these generated IMEI numbers registered with network carriers?

No, these numbers are generated mathematically for testing purposes and are not registered on active cellular networks.

What is a TAC prefix?

The Type Allocation Code (TAC) is the initial 8-digit portion of the IMEI that identifies the device manufacturer and model.

How does the generator ensure the IMEI is valid?

It calculates the final digit using the Luhn algorithm, which is the standard checksum formula used for IMEI validation.

Can I generate multiple IMEIs at once?

Yes, you can generate up to 100 valid IMEI numbers in a single request.

Can this tool be used to change my phone's IMEI?

No, this tool only generates numbers for testing and simulation; it cannot modify the hardware identifier of a physical device.
