The Brotherhood registration[1] is an alphanumeric code identifier unique to each member of the Brotherhood of Steel.


Every number is structured as follows:

  • XX are two capital letters representing a member's last name (or chosen name). The usual rule is that the first two consonants are selected (Maxson returns MX).
  • YYY is the serial number. Elder Arthur Maxson has the lowest number as the Supreme Commander, 001.
  • ZZ is the rank of the holder, updated as they advance through the ranks. Depending on the rank, it may be a single letter or two.
