SEATTLE prefixes in area code 206
NANPA records 676 assigned NXX blocks to rate center SEATTLE in area code 206, 89.9% of the 752 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 48 holders hold those blocks, the largest being QWEST CORPORATION (235), T-MOBILE USA, INC. (87), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WA (57). The earliest assignment on record here is 2001-01-23 and the most recent 2026-05-14. 351 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
