Portland, ME Area Code

Area code serving Portland

Portland sits in Maine, part of the Northeast region and the Eastern Time zone. Its area code is 207, which covers the entire state of Maine. 207 has no overlay today, so every Portland landline and mobile number with a local code starts with 207.

207 has served the area since 1947, as one of the original 1947 North American area codes. If the region runs low on numbers, regulators will most likely add an overlay code on top rather than split the area, which would make 10-digit dialing mandatory.

Getting a Portland phone number

Any new landline, mobile or VoIP number from a local carrier in Portland gets the 207 area code. Numbers come from the blocks each carrier holds in the area; a number ported in from elsewhere keeps its original area code, so you may also see out-of-state codes locally.

Dialing in Portland

Portland is covered by the single area code 207 with no overlay, so some local calls may still connect with seven digits. Dialing all 10 digits (area code + seven-digit number) always works and is the safest habit. From outside the US, dial +1, then the area code and number. See 10-digit dialing and overlay area codes for the background. For every code in Maine, visit the Maine area codes page.
