The purpose of this legislation is to require the United States Postal Service (USPS) to create a single, unique ZIP Code specifically for the town of Swanzey, New Hampshire. Currently, Swanzey may share ZIP Codes with nearby areas, which can lead to confusion in mail delivery and address identification. The key provision of this legislation mandates that within 180 days of the law being enacted, the USPS must assign a distinct ZIP Code that covers only the entirety of Swanzey.
