P Codes

P-code is an abbreviated term for 'Place Code'.

P-codes resolve the basic issue of what we all call a place. Using place-names as identifiers can easily lead to confusion over spelling, different languages or scripts as well as duplication.

P-codes are similar to zip codes and postal codes and are part of a data management system that provides unique reference codes to individual locations. These codes provide a systematic means of linking and exchanging data and analyzing relationships between them. Any information that is linked to one location with a p-code can be linked and analyzed with any other.
