The following is a list of nations' three-letter codes used by the FMF.
List of currently-used codes by nation
This is a list of codes which are in current use by the FMF.
List of all-time nations by code
This list includes all codes ever used by the FMF, including those of former member nations. Active nations are highlighted in green. Nations highlighted in red were never represented in an FMF-sanctioned match during their membership.
A small number of codes have been re-used by the FMF; typically by official successor teams with similar names to their predecessor team.
These codes were issued to teams which were never full FMF members but which had conditional membership for a short period of time.
