WINNEMUCCA prefixes in area code 775

NANPA records 12 assigned NXX blocks to rate center WINNEMUCCA in area code 775, 2.0% 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. 7 holders hold those blocks, the largest being ONVOY, LLC - NV (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NV (2), BANDWIDTH.COM CLEC, LLC - NV (2). The earliest assignment on record here is 2001-07-10 and the most recent 2024-10-07. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
