SANTA ROSA prefixes in area code 707
NANPA records 144 assigned NXX blocks to rate center SANTA ROSA in area code 707, 18.3% 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. 23 holders hold those blocks, the largest being PACIFIC BELL (41), NEW CINGULAR WIRELESS PCS, LLC (28), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (14). The earliest assignment on record here is 2001-10-18 and the most recent 2024-02-20. 85 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 codes 369, 520, 575, 956 – overlay codes cover the same geography, so a rate center is served by all of them.
