Synth designations[1][2] are 4-character identification codes used by synths developed by the Institute. Within the Institute they serve as a synth's name, and they are also used along with a recall code to initialize a factory reset.

StructureEdit

Each synth designation is formatted as follows:

AX-XX
  • A is an alphabet character.
  • Xs are numbers in the range of 1 to 9.

An X typically designates a courser, though A and Z designations also occur.
