Basic Registration of Addresses and Buildings (BAG)

What is it?

The Basic Registration of Addresses and Buildings (BAG) contains the details of all addresses and buildings in the municipality. The locations of mobile homes and moorings for houseboats are also included in the BAG. Government organizations are required to use the data from the BAG.

You can view the BAG via the Kadaster's BAG Viewer.

How does it work?

The BAG Viewer is free for everyone to use.

More information about the BAG can be found on the Land Registry website .

What to do.

If you see incorrect information in the BAG, you can request that the information be corrected. To do so, you submit a so-called feedback report. You will automatically receive a notification once the municipality has processed your feedback report.
