Maine Post Offices
Listing data as of July 31, 2026 · Confirm on USPS.com
Maine's 50 post offices each serve their own town — a perfect one-to-one match that reflects just how many small, independent communities are spread along the state's rocky coastline and deep interior woods. Many of Maine's smaller coastal and inland offices see a real seasonal swing, busier in summer with tourists and seasonal residents than in the depths of winter. Find your Maine town in the list below.
