SANJOAQUIN prefixes in area code 559
NANPA records 7 assigned NXX blocks to rate center SANJOAQUIN in area code 559, 0.9% 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. 5 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (3), COMCAST PHONE OF CALIFORNIA, LLC (1), METROPCS, INC. (1). 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
