Washington area codes
The table below lists every active Washington area code with its coverage, service date and prefix count. 3 of the 6 codes are overlays — added on top of existing territories as numbers ran short.
Geographically the map reads: 360 (Vancouver), 509 (Spokane), 206 (Seattle), 425 (Bellevue), 253 (Tacoma), 564 (Bremerton). Each code page lists its full coverage down to individual rate centers.
2 overlay complexes operate in Washington: 206/564, 360/564. Inside a complex the codes share territory and local calls take ten digits.
Since 2010 the state has gained 1 code: 564 (2017).
Every Washington code keeps Pacific time.
Capacity watch: 509 (exhaust 3Q 2029) is closest to needing relief, per NANPA projections.
206 has served Seattle since 1947, carries 752 active prefixes across 5 rate centers, split among 51 carriers. 414 of its prefixes are pooled — shared between carriers in thousands-number blocks. It is the oldest area code in Washington, in service since 1947. NANPA projects its capacity to last until 2Q 2073 — no relief needed for decades. Local dialing is ten digits.
253, in service since 1997, anchors Tacoma, carries 507 active prefixes across 10 rate centers, split among 27 carriers. 304 of its prefixes are pooled — shared between carriers in thousands-number blocks. NANPA projects its capacity to last until 2Q 2056 — no relief needed for decades. It was created from 206. Local dialing is ten digits.
360 has served Vancouver since 1995, carries 786 active prefixes across 75 rate centers, split among 47 carriers. 553 of its prefixes are pooled — shared between carriers in thousands-number blocks. NANPA projects its capacity to last until 4Q 2057 — no relief needed for decades. It was created from 206. Local dialing is ten digits.
425, in service since 1997, anchors Bellevue, carries 627 active prefixes across 14 rate centers, split among 33 carriers. 405 of its prefixes are pooled — shared between carriers in thousands-number blocks. NANPA projects its capacity to last until 1Q 2044 — no relief needed for decades. It was created from 206. Local dialing is ten digits.
509, in service since 1957, anchors Spokane, carries 759 active prefixes across 119 rate centers, split among 65 carriers. 564 of its prefixes are pooled — shared between carriers in thousands-number blocks. It is covers more rate centers (119) than any other Washington area code. NANPA projects its capacity to last until 3Q 2029. Local dialing is ten digits.
564 has served Bremerton since 2017, carries 92 active prefixes across 32 rate centers, split among 19 carriers. 92 of its prefixes are pooled — shared between carriers in thousands-number blocks. NANPA projects its capacity to last until 4Q 2057 — no relief needed for decades. It was created from 360. Local dialing is ten digits.
Note that toll-free codes (800, 833, 844, 855, 866, 877, 888) sit outside this list — they have no geographic tie to Washington or anywhere else, and are assigned individually from the national SMS/800 registry.
As everywhere in the NANP: these codes say where numbers were issued, not where callers are. Per-code pages break coverage down to rate centers and prefixes.
