BLACKDIMND prefixes in area code 360

NANPA records 4 assigned NXX blocks to rate center BLACKDIMND in area code 360, 0.5% 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. 3 holders hold those blocks, the largest being ONVOY, LLC - WA (2), TELEPORT COMMUNICATIONS AMERICA, LLC - WA (1), QWEST CORPORATION (1). The earliest assignment on record here is 2001-04-23 and the most recent 2019-01-11. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
