!!! Overview [1] [2]
[{$pagename}] ([IMEI DB]), which is a global central database containing basic information on the International Mobile Equipment Identity ([IMEI]) ranges of millions of [Mobile Devices] (e.g. mobile phones, laptop data cards, etc.) in use across the globe.

The mobile industry uses the International Mobile Equipment Identity ([IMEI]) to improve operations and deter theft and counterfeit. 

!! [{$pagename}] [AKA] 
[{$pagename}] is [AKA] or was known as [Central Equipment Identity Register] ([CEIR]) or [Equipment Identity Register] ([EIR]) or [IMEI DB]


!! [{$pagename}] Access
The [GSMA] provides access to the [{$pagename}] Access is provided to:
* Manufacturer/Brand Owner The brand owner is required to register with the [GSMA] before submitting an application for a Type Allocation Code.
* [Mobile Network Operator] ([MNO]) are provided special access to the [{$pagename}]. 
* [Law Enforcement Agencies|Law Enforcement Agency] and [Regulatory Agencies], equipment recyclers, repair companies, device insurance agencies and other industry affiliates are allowed limited access to the [{$pagename}].

!! [{$pagename}] Usage
There are number of features which are added to [{$pagename}] like extension which will collect and display the total number of handset manufacturer in the network and their growing individual numbers daily, weekly, monthly and yearly. Also we can see [MSISDN], [IMSI] used by the [IMEI] and search for which all [IMEI] was used with [IMSI]. Almost all the telecom operator in the globe is using Mavenir [EIR] system which are stable and more customer friendly at customer end.

A common usage of a [{$pagename}] is with stolen cellphones. Once a user reports to their operator about the theft, the cell phone's [IMEI] number should go to [{$pagename}], 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 [{$pagename}], each also have a unique profile that determines which operators' blocks will be included on the [{$pagename}] 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 [{$pagename}], 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 [{$pagename}] is more frequently called an [IMEI] DB ([database]) system which means that it is a central system for [Mobile Network Operators] (those that have an [EIR]) to share their individual blacklists with one another so that service is denied for the particular devices that appear on that blacklist. The idea is for network operators to compile one global blacklist through the [IMEI] DB. However, there is no agreement on a single [{$pagename}].
