The mobile industry uses the International Mobile Equipment Identity (IMEI) to improve operations and deter theft and counterfeit.
A common usage of a International Mobile Equipment Identity Database is with stolen cellphones. Once a user reports to their operator about the theft, the cell phone's IMEI number should go to International Mobile Equipment Identity Database, supposedly making the device unusable in any network (although this does not always work). A key reason this often does not work is that while many operators from many countries contribute IMEIs to the International Mobile Equipment Identity Database, each also have a unique profile that determines which operators' blocks will be included on the International Mobile Equipment Identity Database updates received by each Mobile Network Operator. The United Kingdom networks for example do not receive those block records originated by non-UK networks. Annual fees are required for access to the International Mobile Equipment Identity Database, and access is tightly regulated[1] Contributing operators decide for themselves which handsets they will block from their own networks, and many network operators simply do not participate at all.
Currently, the International Mobile Equipment Identity Database is more frequently called an IMEI DB (database) system which means that it is a central system for Mobile Network Operators (those that have an EIR) to share their individual blacklists with one another so that service is denied for the particular devices that appear on that blacklist. The idea is for network operators to compile one global blacklist through the IMEI DB. However, there is no agreement on a single International Mobile Equipment Identity Database.
