Yeah, I’ve delivered pizza in a city of over 100k people. The whole idea of an address is to figure out where the destination is down to the personal residence. Doesn’t matter if the people are spread out in a single building or many buildings.

I didn’t go knocking on every door any time someone ordered pizza to an apartment. Biggest concern about apartments were if they had a buzzer, if that buzzer worked, and if the code matched the unit number or would be easy to figure out based on the information provided. And if it wasn’t, their phone number was part of the information provided.
