This is the home of the contest country files. These files are used by amateur radio contest logging software to help determine country multipliers from a callsign. The files are updated several times a year, usually before the major DX contests (ARRL DX, CQ WW, etc.) and changes are announced on the various contest and logging software reflectors.

You must use the file that is appropriate for your software. Even though the files are similar, each contains different features that your particular software can take advantage of.
