Interesting. There were also issues reported in the Developers Google API support threads that complained about a lot of areas in France not showing up at all. So apparently Google does not make the connection of a list of zips incorporated or updated. As Tabitha reported, this was working correctly before (I believe) and recently started coming back with mismatch search results.
According to the USPS , zip code 44505 is indeed Youngstown, Ohio you are correct the Google Map query is calling back based on a bunch of different criteria, lat/long, a number or a street in the address, what is searched most often etc. I double checked , i.e. address Country Club Ave Youngstown Ohio, It Geocoded correctly in my SLP locations file (according to Google) : https://www.google.com/maps/place/41%C2%B002'60.0%22N+80%C2%B037'22.5%22Wemail@example.com,-80.6404369,14z/data=!4m2!3m1!1s0x0:0x0
But when I search by zip code, and also forcing the US map domain and also appending country with US, The google query for 44505 comes back with
Main St, Delta Junction, AK 99737, USA
Next, Using the Premier add-on and checking the box called “Google Influenced Guesses”., and “defined boundaries” ” when I then type in a zip code search 44505, still no results , but if I type in Youngstown, my location appears below the map in the results but not with the zip code * I entered but a different one .
So luckily I have another box in Premier that I checked “Show Address Guess ” ( If checked, replace the address the user typed into the address box with what Google thought they meant.)
I then get a result of what Google thinks I meant: Youngstown, OH 44514, USA
Note: I do not have that address zip code in my Locations database, I entered 44505. but at least now it is coming back with a reasonable response.
So again, more detail in search is needed, and if you really want to trick or see what Google is thinking, must have Premier installed..
See second screen shot, is this what you meant about Poland… There actually is a Poland Street or Road in Youngstown Ohio, nearby I wonder if that along with an unrecognized (by Google) zip code might make Google go to the Ukraine , ie. absent all the tricks above ..? We may never know
