The language independent [https://en.wikipedia.org/wiki/ICCF_numeric_notation ICCF numeric notation] as used in [https://en.wikipedia.org/wiki/Correspondence_chess Correspondence chess] is a numerical pure coordinate notation, giving coordinates by two digits (File '1'-'8) rather than letters ('a'-'h') for the file. In case of promotions a fifth trailing digit is used: '1' for queen, '2' for rook, '3' for bishop and '4' for knight.
