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. Sites for caravans and moorings for houseboats are also in the BAG. Government organizations are required to use the data from the BAG.

You can look in the BAG through the Land Registry's BAG Viewer.

How does it work?

The BAG Viewer is free for anyone to use.

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

What to do.

If you see incorrect data in the BAG, you can ask for the data to be adjusted. You then do a so-called feedback. You will be notified automatically as soon as the municipality has processed your feedback.
