Diskussion
Postleitzahlen in Großbritannien (oder auch Postcodes, wie sie dort genannt werden) bestehen aus fünf bis sieben alphanumerischen Zeichen, die durch ein Leerzeichen unterteilt sind. Die Regeln legen fest, welche Zeichen an welcher Position stehen dürfen. Leider sind sie ziemlich kompliziert und voller Ausnahmen. Daher kümmert sich dieser reguläre Ausdruck nur um die grundlegenden Regeln.
