About FullIMEI

A free IMEI checker for people buying, selling or repairing a used phone — and who to talk to when a result needs a second look.

Who runs it

FullIMEI is operated by StandupCRM LLC, Cumberland, Rhode Island, USA. StandupCRM LLC builds StandupCRM, software that independent phone repair shops use to run their counters, and the people behind it also run a phone repair shop in Rhode Island.

That is where this checker comes from. Before a repair shop buys a trade-in, resells a phone or starts a repair, it checks three things: is this the device it claims to be, is it locked to a carrier, and has it been reported lost or stolen. FullIMEI puts that same counter routine in front of anyone with a phone in their hand, free.

How the results are produced

The number is validated with its check digit, the device is identified from the IMEI's Type Allocation Code, and carrier eligibility systems are asked whether the handset is locked or reported. Lock status answers most reliably for phones sold through T-Mobile and Metro; when no database answers, the result says unknown — it is never filled in as clean. The full method and its limits are on the free IMEI check page, and a line-by-line example is in the sample result.

FullIMEI is informational. We do not unlock phones, we cannot remove a blacklist entry, and we do not sell personal data; the privacy policy lists exactly what is stored for each check.

Corrections

If a result or a guide is wrong — a device named incorrectly, a lock status you can prove is out of date — tell us with the IMEI's first eight digits and what you expected. We fix guide errors and report data errors upstream.
