Official names

All the municipality, city and street names are compliant with official governmental data. For example the official name of The Hague is "'s-Gravenhage" instead of "Den Haag".

Official boundaries

Addresses are always assigned to the correct city and municipality, regardless of the numerical part of the postcode. Places such as Buurmalsen and Sibculo are used correctly in two municipalities, which only exist in one municipality in the PTT / PostNL database.

The difference between Basic and Pro

The Basic database contains only the range of a postcode (e.g.; even numbers 2–10). The Pro database contains all available individual house numbers of a postcode (e.g.; numbers 2, 4, 6, 10). With the Pro database you can accurately determine if a specific house number exists (in the example: number 8 does not exist). The Basic database contains fewer records and is therefore smaller and can be searched much faster.
