YORBALINDA prefixes in area code 714

NANPA records 19 assigned NXX blocks to rate center YORBALINDA in area code 714, 2.4% 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 PACIFIC BELL (8), T-MOBILE USA, INC. (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). The earliest assignment on record here is 2001-05-10 and the most recent 2013-11-19. 16 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 657 – overlay codes cover the same geography, so a rate center is served by all of them.
