[Geocode] P.O. Box or Private Bag's Postal Code is not supported by GS7

Question

Despite Postal Code is indicated by Y as supported in the following "Geocode local coverage" page, you may still cannot find them:

https://www.here.com/docs/bundle/geocoding-and-search-api-developer-guide/page/topics/geocode-local-coverage.html

For example, the postal code 76912 in New Zealand and 20038 in Germany.

Answer

Check the type of the Postal Code that you search, and make sure they are not P.O. Box (Private Bag's Postal Code).

HERE Geocoding and Search API v7 (GS7) relies on RMOB, which does not include those P.O. Box typed postal codes.

RMOB stands for Relational Map Object Base, an Oracle database stores the data for HERE core navigational map data products

Example

In the following examples, the following PO Box or Private Bag postal codes are not searchable by HERE GS7:

Private Bag 76912, Manukau City 2241, New Zealand - Postal Code: 2241
PO Box 1334, Crows Nest, NSW, 1585, AUSTRALIA - Postal Code: 1585
* PO Box 671, East London, 5200 South Africa - Postal Code: 5200

However, the postal code listed between the city and country names are supported and searchable.

This is a spec of HERE Geocoding and Search API v7 that PO Box or Private Bag postal code are not supported.

This spec should be added to the HERE documentation of GS7 and will be added soon.
