The area code 207 is located in Portland, Maine.
Area code 207 covers the entire state of Maine, including the coastal city of Portland on Casco Bay. It is Maine’s only area code, making it a key part of the state’s identity and helping callers quickly recognize a Maine phone number. First established in 1947 as one of the original North American numbering plan codes, 207 has never been split or overlaid. From the rocky shoreline and lighthouses to inland forests and the Canadian border, 207 connects every corner of Maine.
Area code 207 serves major communities across the state, including:
These cities and towns sit near well-known landmarks like Portland Head Light, Acadia National Park, and Mount Katahdin in Baxter State Park. Whether you’re calling a business on the waterfront or a home far up north, 207 keeps the state connected. All numbers in this area code use the Eastern Time Zone (ET).
A small but notable fact: Maine is one of the few U.S. states still served by a single statewide area code. That makes 207 easy to recognize on caller ID and helps keep a strong sense of local identity. “According to the North American Numbering Plan Administrator (NANPA), 207 was assigned in 1947 and covers the entire state of Maine.” This long-running, single-code setup spans everything from York County’s beaches to Aroostook County’s forests, all under one familiar number—207.
