Install StreetComplete and put some of them in. Spread the word, it's really low effort.

True to some extent. I know there’s been a big effort to get buildings mapped in the US, but it’s not always possible to get house/street numbers from aerial imagery.

Once buildings are mapped you can either add the remainder of the details with on the ground mapping (e.g using an app like StreetComplete) or if the data (e.g from the government) becomes open and available to use.

It's all dependant on the community, if there's missing data that you can add, please do! StreetComplete is a very acessible way to contribute

Did you report it? Maybe no one noticed yet.

OSMand maps didn’t for my neighborhood but magic earth did so check that out maybe

I've used OSM while staying in a smaller town and the street data was good. It obviously depends on how much the public has contributed to data for your area, which is likely to be a lot for major cities, but there may also be people contributing decent data for less populous areas too.
