[Talk-us] Importing addresses from TIGER

[Saikrishna Arcot]

Ah, ok. I wasn't aware that Nominatim uses the address ranges as a 
fallback. I typically use the data exports offline in OsmAnd, and so 
don't see the address ranges from the TIGER data.

Does the Public Domain status mean that they can be used and imported 
into OpenStreetMap? I might start soon on adding addresses in Atlanta.
