Editing ZIP Code (section)

== Relationship with local government boundaries ==
Each ZIP Code has one or more "postal city" names assigned to it. Since ZIP Code boundaries are based on the areas served by each physical post office, they often do not coincide with the boundaries of local government units. For example, suburban and [[Unincorporated area|unincorporated areas]] may share a postal city name with a neighboring municipality, even if no part of its ZIP Code is actually within that city.<ref>{{Cite web |last=Stevens |first=Nye |date=2006-06-23 |title=Changing Postal ZIP Code Boundaries |url=https://sgp.fas.org/crs/misc/RL33488.pdf |access-date=2024-09-09 |publisher=Congressional Research Service |pages=2}}</ref>
