LATHROWLLS prefixes in area code 775

NANPA records 4 assigned NXX blocks to rate center LATHROWLLS 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. 4 holders hold those blocks, the largest being NEVADA BELL (1), ONVOY, LLC - NV (1), PEERLESS NETWORK OF NEVADA, LLC - NV (1). The earliest assignment on record here is 2018-12-20 and the most recent 2022-01-13. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
