CAMPBELL prefixes in area code 408
NANPA records 43 assigned NXX blocks to rate center CAMPBELL in area code 408, 5.5% of the 787 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 (18), T-MOBILE USA, INC. (7), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (5). The earliest assignment on record here is 2001-03-22 and the most recent 2013-03-08. 31 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 218, 235, 430, 573 – overlay codes cover the same geography, so a rate center is served by all of them.
