Why Are There Multiple Zip Codes?

Zip codes (Zone Improvement Plan) were introduced by the United States Postal Service (USPS) in 1963 to improve the efficiency of mail sorting and delivery. Over time, as populations grow and suburban areas expand, the USPS may create new zip codes or adjust boundaries. This can lead to situations where a single town or municipality might span multiple zip codes, or conversely, a single zip code might cover parts of several towns.

These variations are designed to optimize delivery routes and ensure that each postal worker has a manageable workload. For the recipient, it means that the correct zip code is vital for prompt service.
