CARSONCITY prefixes in area code 775

NANPA records 48 assigned NXX blocks to rate center CARSONCITY in area code 775, 8.0% 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. 15 holders hold those blocks, the largest being NEVADA BELL (13), T-MOBILE USA, INC. (7), ONVOY, LLC - NV (6). The earliest assignment on record here is 2001-05-23 and the most recent 2026-09-29. 30 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 989 – overlay codes cover the same geography, so a rate center is served by all of them.
