Key Register of Addresses and Buildings (BAG)

The Basic Registry of Addresses and Buildings (BAG) contains the data of all addresses and buildings in the municipality. Pitch locations for mobile homes and berths 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 BAG Viewer of the Cadastre.

How does it work?

The BAG Viewer is free for everyone to use.

More information about the BAG can be found on the website of the Cadastre.

What to do?

If you see incorrect data in the BAG, you can request to have the data adjusted. You then submit a so-called feedback report. You will automatically receive a notification as soon as the municipality has processed your feedback.
