A mobile identification number (MIN) is a serial number that uniquely identifies a cell phone services subscriber within a mobile carrier network. It is used by mobile phone services providers to identify subscribers within its database, specifically when routing calls.
As with the landline home numbers, the mobile numbers' middle three-digit part is extended to four digits (e.g., 01X-XXXX-XXXX) due to the increased number of mobile phone users. For mobile numbers in the international context, 82 (0)1X-XXX-XXXX or 82-(0)1X-XXXX-XXXX are most often used.
