  “PostZon” Geographic Data:


“PostZon” data, or geographic data, primarily provides postcode to Longitude and Latitude conversion. This conversation can be used to calculate the straight line distance between two postcodes, which is provided in all of our API offerings.

This data can be taken to the next level to provide a “Nearest Store/Service” locator for a web site. This provides your customers a means of finding their nearest store, given their home postcode.

PostZon Data Uses/Features:


Data returned

This is specialised data such as OS reference, Longitude, Latitude, NHS District , Health Authority codes, Local Authority Electoral Ward codes. The PostZon data has been consolidated from various sources, such as Ordinate Services, NHS, etc. The most useful information is Longitude and Latitude. 

  Note: Some Postcodes return no PostZon Data, such as PO Boxes. It is a good idea to test any bespoke program against such postcodes. Examples are AB10 1BH, AB10 1DQ, AB10 1DU, AB10 1EP. 

Distance between two postcodes

The distance between two postcodes can be returned. Simply call with Postcode and “Home postcode” provided in the parameters. Our service will then return the distance in km.  So approximate charges could be applied to a customer based on the straight line distance.

Postcode to Longitude/Latitude

This is the main use of PostZon data. Simply call with the target Postcode and the PostZon data service will return the Longitude and Latitude. Ideal for mapping and calculating distances.

Longitude/Latitude to Postcode

To get the PostZon record by Longtitude/Latitude, (closest within 10Km) set postcode to the "Longtitude|Latitude" (separated by |). The Postcode found will be returned in pz_postcode.

Town to Longitude/Latitude
