RNCHOPNQTS prefixes in area code 858
NANPA records 22 assigned NXX blocks to rate center RNCHOPNQTS in area code 858, 3.9% of the 564 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. 12 holders hold those blocks, the largest being PACIFIC BELL (6), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - CA (3), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2002-08-30 and the most recent 2026-05-21. 18 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
