It's possible, but I don't think so. I did a conversion of some addresses in Sandy Springs (at least in the area defined as Sandy Springs in OSM), and all of the addr:city values were Atlanta. I'll check, though, to see if the postal city is actually Atlanta.

The zip code data in this dataset seems to match up well with the ZCTA. There are about 20-30 addresses (a relatively low percentage compared to the number of addresses present) in a midtown Atlanta sample I have (most likely due to the small region having their own zip code). In another sample outside of the city, there were no mismatching zip codes.
