#WPX Prefixes

In CQ WPX a prefix is, in general, the letters and digits at the start of a callsign up to and including the last numeral. Each different prefix you work is a multiplier, so two stations from the same country can bring two multipliers if their numerals differ. Portable designators, special event calls and unusual formats follow special rules that are set out in the contest rules. Articles under this tag explain how prefixes are formed and how to log them without errors. Prefix statistics are also useful after the contest to see where your multipliers came from.
