Programmers fallacies about postcodes:
- A postcode covers a small geographic area
- A postcode is good enough to locate an end user for generating location suggestions
- A postcode will be in a single timezone
- A postcode only has a single state
- A postcode has no exclaves/enclaves
I would like you to meet 0872. Australia's largest postcode (I think), covers 3 states, has two cut outs (Warbuton and Alice Springs), and even still some mail outside of this area is routed via 0872
@xssfox At least in the case of the US's Zip codes there's also:
- A zip code is associated with only a single location
- A zip code has any geographic region associated with it
- A zip code is associated with something stationary
@xssfox @crumbcake Ah yes because here (and probably other places too) Navy ships can be zip codes. Sometimes multiple ships share one, sometimes not.
