Phone network identification helps a phone find the right cell tower to connect with when making a call. It is important for both security and to ensure that a mobile device is actually the device it claims to be. Our carrier lookup tool provides up to date information sourced from global directories, live porting checks, and the number portability administration center (NPAC). Our tool is a valuable resource for discovering the original carrier associated with a phone number before it was ported.

A MIN is an phone network identification used to manage and identify devices in the cellular network. It is used in conjunction with a mobile directory number (MSISDN) to route calls and manage data. A MIN is unique to each device and does not change when the device is switched between networks.

When your mobile phone announces itself to a cellular network, it is looking for a shared ID that matches the IMEI. If it finds that match, the cellular network allows it to make or receive calls and send text messages. If the IMEI is not recognized, the cellular network will block the device from gaining access to its networks.

Why Is Carrier Identification Important?

Some cellular networks, such as Verizon in the US, use the IMEI to cross-reference the phone’s registration name with the caller’s contact name. This feature reduces skepticism from consumers who are wary of unknown callers and can improve call engagement metrics by reducing the number of calls that go unanswered. Other systems use various location approaches including Wi-Fi, GPS, LTE, IP addresses and a combination of these to determine the approximate location of the device.
