New law would let towns pay USPS to redraw ZIP code boundaries

What does this do?

The CIPZIP Act of 2025 creates a temporary program letting the Postal Service accept money, property, or services from state, local, or tribal governments to cover the cost of changing ZIP code boundaries. If cost is the only reason for denial, USPS must disclose the cost estimate, allow at least 30 days for a funding proposal, and approve the change if the government agrees to pay.

Who does it affect?

Local, state, and tribal governments seeking ZIP code boundary changes, and the U.S. Postal Service, which must track and report on requests. Residents may be indirectly affected through changes to mailing addresses or local identity.

Why does it matter?

The change could make it easier for communities to get ZIP code boundaries adjusted for reasons like delivery confusion or economic development, but it also shifts some administrative costs onto local governments. The program expires after seven years unless Congress renews it.

What does it cost, and who pays?

• Local govts may fund cost of change
• USPS provides cost estimate first
• 30-day window to propose funding
