Every member of the BJCP is assigned an identification number, in order to keep track of your experience points in our database. Generally, your number is assigned when you take the BJCP exam for the first time, and remains with you forever. The first letter of the number indicates the BJCP region of the location where you lived when you took your first exam, and does not change even if you move permanently to a different region. Since our regions have changed over time, and because members move over time, the letters have less significance. The remaining digits of the number are assigned sequentially within each region, and don’t really mean anything, except that a lower number probably means you took the exam before someone with a higher number.
