Postal code
Placement of the code
Postal services have their own formats and placement rules for postal codes. In most English-speaking countries, the postal code forms the last item of the address, following the city or town name, whereas in most continental European countries it precedes the name of the city or town. When it follows the city, it may be on the same line or on a new line.

In Brazil the 8-digit postcodes are an evolution of the five-digit area postal codes.
