IMEI validation confirms the number is structurally correct. To check if the device is blacklisted, stolen, or carrier locked in Australia, 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.
Australian carriers and law enforcement can flag IMEIs as stolen or lost via the AMTA national database. Blacklisted phones may still power on but cannot connect to Telstra, Optus, or Vodafone networks. Check via the services above before any purchase.
A carrier-locked phone only works on one network. In Australia, carriers are legally required to unlock phones once contract obligations are met. Unlocked phones have higher resale value and work on any AU carrier.
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.
