Free IMEI Tools

Three small utilities that sit alongside the checker: prove an IMEI is even real, work through a list of them, and find the one you checked last week.

The main checker answers one question about one phone. These tools cover the jobs around it — the ones that come up when you are buying several handsets, when a number looks wrong before you have even looked it up, or when you cannot remember which of four phones came back clean.

All three are free, none needs an account, and two of them work with no network connection at all. The validator and your history run entirely in your browser: the arithmetic happens on your device and the history never leaves it.

Which one do you need?

The validator is for a number that looks suspicious. It splits the IMEI into its parts — the allocating body, the eight-digit Type Allocation Code that names the model, the unit serial and the final check digit — and recomputes the checksum in front of you. An IMEI that fails it was mistyped or invented, and you have learned that without querying anything.

The bulk checker is for a list: a shop assessing trade-ins, a reseller working through a pallet, anyone holding more than three phones. It de-duplicates, drops the numbers that cannot be valid, then runs the rest through the same free check one at a time at a sensible pace, and hands you a CSV at the end.

Your history is the list of checks this browser has run, stored on your own device. It is there so you can re-run a phone, copy a share link you closed, or simply remember which IMEI was the clean one. Clearing it is one button and it takes nothing with it.
