Postal code

A postal code is a series of letters and digits appended to a postal address for the purpose of sorting mail. Every postal service (usually having their service area defined by national borders) has a different format and placement for the postal code. In most English-speaking countries, the postal code goes after the name of the city or town, whereas in most European countries it goes before it and is often prefixed with a country code. This country code is similar to the one used on car license plates.

Though usually postal codes are assigned to geographical areas, sometimes this is not the case: special codes may be assigned to institutions with large volumes of post, such as government agencies and large commercial companies. One example is the French Cedex system.

Before postal codes as described here were used, large cities were often divided into postal zones, usually numbered from 1 up within each city. Postal code systems often incorporate the old zone numbers, as in London, for example.

Most postal codes, in the countries that have them, are numeric. The few using alphanumeric postal code systems (with letters and digits) are: Argentina, Bermuda, Brunei, Canada, Malta, Netherlands, United Kingdom, Venezuela.
