WHATCOMCTY prefixes in area code 360
NANPA records 69 assigned NXX blocks to rate center WHATCOMCTY in area code 360, 8.8% of the 786 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. 10 holders hold those blocks, the largest being ZIPLY FIBER NORTHWEST, LLC DBA ZIPLY FIBER (16), QWEST CORPORATION (15), TELEPORT COMMUNICATIONS AMERICA, LLC - WA (9). The earliest assignment on record here is 2001-04-16 and the most recent 2025-09-19. 45 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 564 – overlay codes cover the same geography, so a rate center is served by all of them.
