VACAVILLE prefixes in area code 707

NANPA records 37 assigned NXX blocks to rate center VACAVILLE in area code 707, 4.7% 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. 12 holders hold those blocks, the largest being PACIFIC BELL (12), NEW CINGULAR WIRELESS PCS, LLC (5), ONVOY, LLC - CA (5). The earliest assignment on record here is 2001-12-27 and the most recent 2022-10-12. 28 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 code 369 – overlay codes cover the same geography, so a rate center is served by all of them.
