Practical International Data Management - Postal codes

Definition

Codes used within postal addresses to indicate a geographic area, point or route or as a pointer to a company or building. Used to improve postal sorting and delivery and to prevent confusion when two streets share the same name within a single populated place.

Note: Postal code is the generic term for a code used in a postal address to aid in sorting and delivery. Other terms are used by particular postal authorities. There is a variation in terminology between language (Postal Code, Code Postal, Código Postal, Kody pocztowe) and also within languages (Postal Code, Postcode, ZIP Code, PIN Code etc.)
