YUCCA VLY prefixes in area code 760

NANPA records 6 assigned NXX blocks to rate center YUCCA VLY in area code 760, 0.8% 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. 3 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (4), ONVOY, LLC - CA (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - CA (1). The earliest assignment on record here is 2011-12-05 and the most recent 2011-12-05. 4 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 442 – overlay codes cover the same geography, so a rate center is served by all of them.
