VASHON prefixes in area code 206
NANPA records 8 assigned NXX blocks to rate center VASHON in area code 206, 1.1% 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. 6 holders hold those blocks, the largest being CENTURYTEL OF WASHINGTON, INC. DBA CENTURYLINK (2), ONVOY, LLC - WA (2), LEVEL 3 COMMUNICATIONS, LLC - WA (1). The earliest assignment on record here is 2004-09-01 and the most recent 2025-10-17. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
