The code of the Emerald City
Seattle has used 206 since 1947, and locals still treat it as the city's signature.
Tech teams in South Lake Union, cafes in Capitol Hill and trades working the hills of Queen Anne all know it on sight. A 206 number tells customers you belong to the city proper, close enough to meet at a coffee shop or show up at the job site. That familiarity matters in a place where people are quick to screen calls from numbers they do not recognize.
