RSVL CTHT prefixes in area code 916

NANPA records 18 assigned NXX blocks to rate center RSVL CTHT in area code 916, 2.3% of the 785 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. 9 holders hold those blocks, the largest being CONSOLIDATED COMMUNICATIONS OF CALIFORNIA COMPANY (9), NEW CINGULAR WIRELESS PCS, LLC (2), IP HORIZON LLC (1). The earliest assignment on record here is 2001-11-30 and the most recent 2017-07-31. 13 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 279 – overlay codes cover the same geography, so a rate center is served by all of them.
