IMEI checker
About this tool
Enter a 15-digit IMEI and this tool checks it with the Luhn algorithm, then splits it into its parts: the 8-digit TAC, the 6-digit serial, and the final check digit. The TAC is looked up in a small bundled dataset to guess the brand/model.
Everything runs in your browser. Nothing is uploaded, and this does not query carrier blocklists or the GSMA database.
What is an IMEI?
IMEI stands for International Mobile Equipment Identity, a unique 15-digit number that identifies your phone on a mobile network. Dial *#06# on any phone to see yours.
- TAC (digits 1-8): the Type Allocation Code, which identifies the brand and model.
- Serial (digits 9-14): the individual device serial number.
- Check digit (digit 15): a Luhn checksum that catches typos.
Tips
- A valid Luhn check only means the number is well-formed, not that the device is genuine or unblocked.
- A TAC missing from the dataset doesn't mean the IMEI is fake; coverage is partial.
- Dual-SIM phones have two IMEIs, and
*#06#shows both. - To check blocklist/stolen status, use your carrier or an official IMEI service.
About the IMEI Checker
Enter any 15-digit IMEI and you get two things instantly, right in your browser. First it runs the Luhn algorithm, the same checksum used on credit cards, to confirm the number is mathematically well-formed and catch typos. Then it splits the number into its meaningful parts and looks up the Type Allocation Code (TAC) against a bundled dataset to suggest the device brand and model.
Nothing is uploaded. The IMEI you enter never leaves your device, and the tool does not contact the GSMA database or any carrier blocklist. Treat it as a fast sanity check and learning tool, not an official device-status service.
How an IMEI is structured
- TAC (digits 1-8): the Type Allocation Code, assigned by the GSMA, which identifies the model and the reporting body that issued it.
- Serial (digits 9-14): the manufacturer's serial number for that individual unit.
- Check digit (digit 15): a single Luhn checksum digit computed from the first 14 digits.
How to find your IMEI
Dial *#06# on the phone's keypad, or open Settings, then About phone. Dual-SIM phones have two IMEIs and *#06# shows both. You can also find it printed on the box or under the battery on older devices.
Frequently asked questions
What is an IMEI number?
It is the International Mobile Equipment Identity, a unique 15-digit serial that identifies your phone to mobile networks. Every phone (and every SIM slot) has one.
Does a "valid" result mean the phone is genuine?
No. Valid only means the number passes the Luhn checksum and is well-formed. Counterfeit phones can carry valid-looking IMEIs, and a real phone's IMEI can be cloned. Use it as a typo check, not proof of authenticity.
My TAC wasn't recognized. Is the IMEI fake?
Not necessarily. The bundled TAC dataset is partial and best-effort, so a missing match only means that model isn't in our data. The Luhn result is the authoritative part.
Can you check if my phone is blocklisted or stolen?
No. That requires the GSMA/carrier blocklist, which is a paid service this tool deliberately does not query. Contact your carrier or use an official IMEI-status service.
