Overview[1]#

Mobile Network Code (MNC) is specified in ITU-T E.212 is a three digit code (North America) or two digit code (Everyone else) that is used in combination with a Mobile Country Code (MCC) to identify a Mobile Network Operator uniquely

Mobile Network Code is used within:

• Integrated Circuit Card Identifier (ICCID)
• Home Network Identity (HNI)
• International Mobile Subscriber Identity (IMSI)
• Mobile Global Title (MGT)

North America#

North America nominally uses three-digit Mobile Network Codes whereas the rest of the world uses two-digit Mobile Network Code. Due to this uniqueness, and a lack of support in international networks, carriers which are only uniquely identified via a three-digit Mobile Network Code are NOT compatible with international roaming. As a result, in practice, most major United States carriers have MNCs ending in 0, so that they are uniquely identified by the first two digits, thereby providing their subscribers with compatibility on international networks.
