About Random Nr's IMEI Number Generator

The random IMEI generator produces structurally valid IMEI numbers with a correct check digit, for testing only. Generate one or many, and Random Nr calculates the final Luhn check digit so each number passes a format check while belonging to no real device, which keeps your test data clean and safe to use.

What the 15 IMEI digits mean

An IMEI is not random all the way through. Its structure identifies the device model, then the individual unit, then a check digit.

1 to 8TAC, Type Allocation Codeidentifies the model and manufacturer

9 to 14Serialthe individual device within that model
15Check digita Luhn checksum over the first 14

You can see your own device's IMEI by dialling *#06# on the keypad. The first eight digits, the TAC, are what a network looks up to know exactly which model is connecting.

How the IMEI check digit works

The last digit is a Luhn checksum over the first fourteen, the same formula credit cards use. This generator builds fourteen random digits, respecting the TAC then serial layout, and computes the fifteenth so the whole number validates. A phone with a wrong check digit is rejected by the network, which is why validators test it first.

Why these are test IMEIs not real devices

These IMEIs are structurally valid and pass the Luhn check, but the random TAC does not map to a real model and the number belongs to no handset. They suit testing device registration, inventory forms and validation. For the vehicle equivalent, the VIN generator builds valid 17 character identifiers with their own check digit.

Frequently asked questions

What is an IMEI

A fifteen digit number that identifies a mobile device on a network. The last digit is a Luhn checksum.

Are these real device IDs

No. They are random numbers that pass the Luhn check, not linked to any real handset.

Do they pass validation

Yes. Each IMEI has a correct Luhn check digit, so validators that only test the checksum will accept it.

Can I make several

Yes, up to 500 at once, ready to copy or export.

Is it free

Yes, free and with no sign up.
