Poštovní směrovací číslo (PSČ), the five-digit postal code of the Czech Republic, usually written as three and two digits, as in 110 00. Czechoslovakia introduced it in 1973 and the system has not changed since. The first digit is the postal zone of 1973: 1 Prague, 2 Central Bohemia, 3 western and southern Bohemia, 4 northern Bohemia, 5 eastern Bohemia and western Moravia, 6 southern Moravia, 7 northern and eastern Moravia. Codes starting with 8, 9 and 0 belong to Slovakia. Mail from abroad may put CZ- before the code.
