I am looking for comprehensive address data (incl. house numbers) for Germany. Is there some kind of government agency that provides free downloads?

I know that the BEV (Bundesamt für Eich- und Vermessungswesen) provides this service for Austria.

Are other countries also that generous with their data?

As mentioned. I am particularly interested in a dataset for Germany, but also information about other countries.

I don't know whether this a desired answer but OpenStreetMap has a very good record for Germany! You can use nominatim in prob. 90% of your addresses and it will result in a coordinate based on house numbers!

This plugin is deprecated! There is also a plugin for QGIS called OSMroute which can be used for this purpose!

When it comes to official data I would search on the open data portal for Germany.

I've seen data for:

and probably some more. But there seems to be no open single point of truth.

Another possibility is to pay for the data. GfK will sell it for sure.

    Thanks for the reply, but I currently use OSM and it is only good enough down to the street level. House numbers are missing in most remote areas. – Chris Feb 10 '16 at 14:43
  • as you said: most remote areas... when it comes do dense areas it is well covered. But I think you hit a pain point in German federalism: The data is distributed and not stored in a single database – Riccardo Feb 10 '16 at 14:51
  • @Chris I altered my answer and added a link to a data portal. – Riccardo Feb 10 '16 at 14:57

For Europe I may suggest investigating INSPIRE's Addresses resource:

https://inspire.ec.europa.eu/Themes/79/2892


For Germany check ESRI's source for addresses:

https://opendata-esri-de.opendata.arcgis.com/search?q=Adressen


For Saxony (Free State of Saxony) in Germany, a list with addresses in zip-format can be downloaded from here:

https://www.geodaten.sachsen.de/downloadbereich-hauskoordinaten-4172.html

The inside of the archive includes the following files:

zip_archive

A file with addresses "adressen.txt" looks as following:

More about the structure of txt-file with house coordinates can be found in the PDF document attached below.

Columns (#12 and #13) that represent coordinates are projected in EPSG:25833.
