Milwaukee, WI Area Code

Area code serving Milwaukee

Milwaukee sits in Wisconsin, part of the Midwest region and the Central Time zone. Its area code is 414, which covers Milwaukee and Milwaukee County in southeastern Wisconsin. 414 has no overlay today, so every Milwaukee landline and mobile number with a local code starts with 414.

414 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 Milwaukee phone number

Any new landline, mobile or VoIP number from a local carrier in Milwaukee gets the 414 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 Milwaukee

Milwaukee is covered by the single area code 414 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 Wisconsin, visit the Wisconsin area codes page.
