@erikstl @reclus @switchingsocial@mastodon.at street number data may be there but OsmAnd doesn't do interpolation of it. It only finds the start and end street numbers.
Other OSM interfaces will take the length and for a number in the even/odd sequence calculate how far along that the house number likely is.
