Home Network Identity (HNI) codes identify a mobile subscriber’s home network and is assignable to mobile network operators with international roaming capabilities. The HNI is comprised of the first six digits of the IMSI: the three-digit Mobile Country Code (MCC) and the three-digit Mobile Network Code (MNC). The Mobile Station Identification Number (MSIN), which makes up the remaining nine digits of the IMSI, is administered by the network operator to which the HNI is assigned.
IMSI can now be used for Shared HNI for Citizens Broadband Radio Service (CBRS) operations. The CBRS assignments can be found here.
