SAN LUCAS prefixes in area code 831
NANPA records 4 assigned NXX blocks to rate center SAN LUCAS in area code 831, 1.0% of the 406 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 LEVEL 3 COMMUNICATIONS, LLC - CA (2), PACIFIC BELL (1), IP HORIZON LLC (1). 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
