CBRS Assignments

Below is the list of IMSI codes for a Shared HNI for Citizens Broadband Radio Service (CBRS). Each code uniquely identifies the mobile terminal/user, IMSI Block Number (IBN), which is related to the CBRS network operator and the home country of the network and of the mobile terminal/user.


The overall IMSI format remains the same. For the purposes of defining an HNI for the CBRS range, the MSIN, with is the last nine digits of the code, is divided into two components. The first four digits are used as the IMSI Block Number (IBN), the remaining five digits are used for the User Identification Number (UIN).
