Cedar Rapids, IA Area Code

Area code serving Cedar Rapids

Cedar Rapids sits in Iowa, part of the Midwest region and the Central Time zone. Its area code is 319, which covers eastern Iowa including Cedar Rapids, Iowa City, Waterloo and Burlington. 319 has no overlay today, so every Cedar Rapids landline and mobile number with a local code starts with 319.

319 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 Cedar Rapids phone number

Dialing in Cedar Rapids

Cedar Rapids is covered by the single area code 319 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.
