PORTOLA prefixes in area code 530
NANPA records 3 assigned NXX blocks to rate center PORTOLA in area code 530, 0.4% of the 782 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 BANDWIDTH.COM CLEC, LLC - CA (1), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (1), PACIFIC BELL (1). 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
