EMPIRE prefixes in area code 775

NANPA records 8 assigned NXX blocks to rate center EMPIRE 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. 4 holders hold those blocks, the largest being ONVOY, LLC - NV (5), AT&T CORP. - NV (1), NEVADA BELL (1). The earliest assignment on record here is 2020-05-11 and the most recent 2022-03-16. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
