Structure of the FIDE ID

As I mentioned in FIDE Struggles with the Growing Popularity of Ratings, the FIDE ID first appears in the historical rating data for January 1999. The structure of the ID is a one to three digit numeric federation ID, followed by a five digit player ID for players within that federation. For example, my own code 2003740 can be read as 20 for the USA, followed by 03740 for my player ID within all American players.

The first rating list with FIDE IDs had 148 different federations. The codes were assigned as shown in the following table, first sorted by federation alpha code, then by federation numeric ID. The two tables show only the first and last 10 codes for each sort. The third column is the count of players for the federation on the 1999 list.

The 1999 rating list also had four players without properly formatted FIDE IDs. They are shown here with their federation code and 'FIDE ID':-
- FIE; 19; Krasser, Margit
- FIE; 27; Shkrabi, Eric
- IBS; 28; Wassin, S.
- IBS; 20; Zsiltzova, L.

I'll look at this another time.
