FULLERTON prefixes in area code 714

NANPA records 37 assigned NXX blocks to rate center FULLERTON in area code 714, 4.7% 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. 11 holders hold those blocks, the largest being PACIFIC BELL (19), METROPCS NETWORKS, LLC (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). The earliest assignment on record here is 2001-05-10 and the most recent 2012-04-28. 23 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 codes 308, 657, 701 – overlay codes cover the same geography, so a rate center is served by all of them.
