Open device data

Brand & model come from a public, manufacturer-publishable device dataset.

What is an IMEI?

An IMEI is the 15-digit serial number that identifies a mobile device. Its first 8 digits — the TAC — encode the make and model; the last digit is a checksum that catches typos. You can usually find it by dialing *#06#, or in your phone's settings.

What this tells you

  • • The manufacturer and model the IMEI belongs to.
  • • Whether the 15-digit number passes its checksum.
  • • The TAC, serial, and check-digit breakdown.

What it doesn't

  • • The free check is not a blacklist, stolen, or lost-device check.
  • • It does not report carrier-lock or warranty status.
  • • A valid checksum does not mean a device is clean to buy.

Check by brand

Each brand page covers where to find the IMEI on that manufacturer's phones, and which models we can identify.

Guides

  • What is an IMEI?

    An IMEI is the 15-digit number that identifies a mobile device. What each part means, and what it can and cannot tell you.

  • How to find your IMEI

    Four ways to find the IMEI on any phone — the *#06# dial code, device settings, the SIM tray, and the original box.

  • What is a TAC?

    The TAC is the first 8 digits of an IMEI. It identifies the make and model of a device, and it is what a free IMEI lookup actually reads.

  • How the IMEI checksum works

    The last digit of an IMEI is a Luhn checksum. How it is calculated, what it catches, and — importantly — what it does not prove.

  • What an IMEI check cannot tell you

    A free IMEI lookup identifies a device and validates its checksum. It does not prove a phone is unstolen, unlocked, or safe to buy. Here is the line.

  • iCloud activation lock and the IMEI

    Apple retired its public activation lock checker in 2017. What that means for IMEI-based iCloud checks, and the one method that actually proves a device is clear.

  • IMEI registration checks by country

    Some countries run their own IMEI registries — Pakistan's PTA, Turkey, India's CEIR. What those national checks cover, and why they are separate from a device lookup.

  • Checking a used phone before you buy

    A practical checklist for buying a second-hand phone: verify the IMEI matches the device, confirm the model, and know which risks a lookup cannot cover.

  • IMEI vs serial number vs MEID

    Phones carry several identifiers and they are not interchangeable. What IMEI, IMEISV, serial number, MEID and EID each identify.

  • Dual-SIM and eSIM IMEIs

    A dual-SIM phone reports IMEI1 and IMEI2, and an eSIM carries its own. Why one handset has several IMEIs, and which one to use for a lookup.

  • Is it safe to share your IMEI?

    An IMEI is not a password and cannot be used to unlock or track a phone. The real risks are narrower than the scare stories — and worth knowing precisely.

  • Checking devices at scale

    Notes on IMEI checking as a business process — intake screening, what identification does and does not cover, and how to get in touch.
