The purpose of the Community Involvement in Zone Improvement Plans Act of 2025, also known as the CIPZIP Act of 2025, is to create a pilot program that allows for changes to ZIP Code boundaries. This program aims to facilitate collaboration between the United States Postal Service (USPS) and various levels of government, including state, local, and tribal entities, to address the needs of communities regarding ZIP Code adjustments. Key provisions of the act include the establishment of a pilot program where the USPS can enter into agreements with state, local, or tribal governments.
