ENUMCLAW prefixes in area code 360

NANPA records 8 assigned NXX blocks to rate center ENUMCLAW in area code 360, 1.0% 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. 6 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - WA (2), QWEST CORPORATION (2), ONVOY, LLC - WA (1). The earliest assignment on record here is 2002-04-30 and the most recent 2002-04-30. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
