there is some sense in understanding the system (if there is), e.g. if not
all numbers are recorded it allows you to estimate where the one you are
looking for might be, how far it possibly is etc.. This is a typical use
case: you have an address and are looking for it on the ground.

there could be 2 numbers, a distance based on and a recently assigned,
You could also be interested in comparing an official register to the OSM
data, e.g. to find missing spots, check for completeness etc.

good luck with this. In regions with lacking housenumbers I wouldn't put
too much confidence in the road markers...
