Area codes and dialing in Maine
Maine is one of the few US states still covered by a single area code, 207. Because there's no overlap, many local calls can still be completed with seven digits, although dialing the full 10-digit number always works and is the safer habit. 207 serves Portland and the rest of the state, all in the Eastern Time zone.
If Maine ever exhausts its supply of numbers, regulators would almost certainly add an overlay rather than split the state — the modern approach that lets everyone keep their existing number. For now, every Maine number shares the 207 code. Learn the background in how area codes work.
