To direct the United States Postal Service to designate a single, unique ZIP Code for Kinnelon, New Jersey.

HR 6172 directs the United States Postal Service to assign a single, unique ZIP Code specifically for the Borough of Kinnelon, New Jersey, within 180 days of the bill's enactment. This bill requires the USPS to create a dedicated ZIP Code covering only Kinnelon's municipal boundaries, distinct from neighboring areas. The change would simplify mail delivery for residents and businesses within Kinnelon by eliminating the need for multiple ZIP Codes. This is a procedural administrative change, not a policy shift affecting broader public programs or funding.
