OWYHEE prefixes in area code 775

NANPA records 3 assigned NXX blocks to rate center OWYHEE in area code 775, 0.5% 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. 3 holders hold those blocks, the largest being CENTURYLINK COMMUNICATIONS, LLC (1), TON80 COMMUNICATIONS, LLC (1), CENTURYTEL GEM STATE INC-NV DBA CENTURYLINK - NV (1). The earliest assignment on record here is 2015-09-29 and the most recent 2022-02-01. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
