Bellevue, WA Area Code

Area code serving Bellevue

Bellevue sits in Washington, part of the West region and the Pacific Time zone. Its area code is 425, which covers Seattle's eastern and northern suburbs in King and Snohomish counties, Washington. 425 has no overlay today, so every Bellevue landline and mobile number with a local code starts with 425.

425 has served the area since 1997. 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 Bellevue phone number

Any new landline, mobile or VoIP number from a local carrier in Bellevue gets the 425 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 Bellevue

Bellevue is covered by the single area code 425 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 Washington, visit the Washington area codes page.
