In the new version of the PTV Developer Geocoding & Places API V1.13.5 we improved the support of long postal codes.
In the Netherlands it’s common to enter just the (long) postcode and house number. In most cases an exact match is possible but in some rare cases a result with exact house number and with partly exact postcode was returned.
In these cases we now return the exact postcode in Locations by text and Locations by Address.
