SOLEDAD prefixes in area code 831
NANPA records 8 assigned NXX blocks to rate center SOLEDAD in area code 831, 2.0% 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. 7 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - CA (1), IP HORIZON LLC (1). The earliest assignment on record here is 2016-02-15 and the most recent 2023-12-06. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
