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.
Structure[]
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.
