why do we need to use city and state in our addresses if ZIP codes are already linked to the city and state?
In: 100
Some zip codes cross state lines. If you need to know what state somebody is in you can’t get it 100% of the time from state. In practice that only affects a few.
Towns will be a much bigger problem. Lots of zip codes cover more than one small town. If you have a common street name like Main St, Church St, Park St or Railroad St you’d better include the town name. If zip code 12345 covered 3 small towns they might all have a Main St.
