In the city line, the city and the district are printed as a composition joined by a hyphen (exceptions: 004 USA, 006 Great Britain/Ireland, 013 Japan, 015 Germany, 017 South Korea, 019 Denmark) provided that the total length does not exceed 35 characters.

If another city has been specified for the P.O. box, this city is used for the P.O. box address.

The order and structure of the postal code, city, district and region in the city line differs considerably from country to country.
