Are node id values unique?

Test fédération OSMF
1

Hi,

I am looking at osm data files and try to avoid importing the same data for overlapping areas. So I thought of keeping track of imported way id numbers and node id numbers. Will that be accurate? Will the same road and matching nodes in different osm files always have the same id value?

I searched on the topic and found that the node indeed should be unique but that there can be unintended duplicates.

Just asking if my approach would work?

Thanks,
Raul
