thanks to the Belmap data team

Data management is people-work. Through the Belmap feedback service, users have a direct link to the data team.
Have you noticed a new address or is an existing address no longer current? Report it via the fast feedback procedure with guaranteed service.

This way, all customers benefit from each other's reports and our data stewards ensure that Belmap remains your most trusted source.

A stable identifier for each address

New street names, municipal mergers, renumberings. There are many possible reasons for changing address information. In that case you risk losing the link to all the underlying information.

That's why every address in Belmap has a stable and unique ID. In this way, all users can count on maintaining the link between the address and the information in their own database at all times. GIM's update processes are set up in such a way that this stable ID is maintained at all times.

Since 2018 more than 180.000 adresses in Belmap preserved their stable ID compared to open data addresses. 

More than addresses

Accurate insight into buildings and plots

Accurate insight into buildings and parcels, tailored to your needs. In addition to addresses, Belmap contains a wealth of information about buildings and their occupants.


  • Function, characteristics and day/night occupancy of a building give you insight into the occupants and their usage patterns.
  • With GeoType, you learn all about the profile and lifestyle of households.
  • The age of a building and the presence of solar panels provide useful insights into energy consumption.
  • Parcel information gives you information about the geometry of the plot and the presence of gardens and swimming pools.
