MCGILL prefixes in area code 775

NANPA records 8 assigned NXX blocks to rate center MCGILL 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), NEVADA BELL (1), UTILITY TELECOM GROUP, LLC - NV (1). The earliest assignment on record here is 2001-07-10 and the most recent 2022-02-24. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
