COTNWD CRK prefixes in area code 775

NANPA records 8 assigned NXX blocks to rate center COTNWD CRK in area code 775, 1.3% of the 601 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. 5 holders hold those blocks, the largest being ONVOY, LLC - NV (4), AT&T ENTERPRISES, LLC (1), HD CARRIER LLC (1). The earliest assignment on record here is 2008-01-17 and the most recent 2019-08-28. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
