IMEI validation confirms the number is structurally correct. To check if the device is blacklisted, stolen, or carrier locked, use one of these trusted services:
Every IMEI must be exactly 15 digits and pass the Luhn algorithm — a checksum that catches typos and fabricated numbers. We validate this instantly, for free.
The first 8 digits (called the TAC — Type Allocation Code) identify the device manufacturer and model. We decode this from the GSMA TAC database to tell you what device an IMEI belongs to.
Carrier networks and law enforcement can flag IMEIs as stolen or lost. Blacklisted phones may still power on but cannot connect to carrier networks in the US. Check via the services above before any purchase.
A locked phone only works on one carrier's network. Unlocked phones fetch higher resale value and work globally. Full IMEI check services reveal lock status from carrier records.
Battery health, cosmetic condition, and hardware functionality are not in IMEI records. Always inspect or request photos of the physical device alongside running an IMEI check.
