Duluth, MN Area Code

Area code serving Duluth

Duluth sits in Minnesota, part of the Midwest region and the Central Time zone. Its area code is 218, which covers northern Minnesota including Duluth, Moorhead, Bemidji and the Iron Range. 218 has no overlay today, so every Duluth landline and mobile number with a local code starts with 218.

218 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 Duluth phone number

Any new landline, mobile or VoIP number from a local carrier in Duluth gets the 218 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 Duluth

Duluth is covered by the single area code 218 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.
