How can I get Google Maps to stop routing people to the wrong address?

As a quirk of street layouts and house numbering, the house I live in has the same street name and number as another house about 20 minutes away in a different town. Ie both addresses start “123 Foo Street,” but then have two different cities and zip codes.

Google Maps does not understand this. If you enter any part of my address, even the entire address including city and zip code, it still routes to the other city.

This causes an astonishing number of problems. Visitors getting lost is the least of it: Apple Maps works fine, and if people don’t have Apple we just tell them another close by address that works correctly.

But whenever we get deliveries, technicians, etc. it doesn’t work. I can’t get an Uber. Our school district had a bunch of problems because some stupid computer of theirs uses Google to geolocate us and considers us out of district: it took dozens of calls and complaints to get our kids enrolled in the school walking distance from the house.

I have tried suggesting an edit to both addresses, but that doesn’t work. The full address is correct for both locations, the problem is something to do with Google’s autocomplete ranking, I guess it ranks the other city first and “corrects” anything you enter, including the full city and zip code.

Anyone know any way to fix this kind of thing?
