YERINGTON prefixes in area code 775

NANPA records 4 assigned NXX blocks to rate center YERINGTON in area code 775, 0.7% 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 LEVEL 3 COMMUNICATIONS, LLC - NV (2), UTILITY TELECOM GROUP, LLC - NV (1), FRONTIER COMMUNICATIONS OF THE SOUTHWEST INC. - NV (1). 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
