HOPLAND prefixes in area code 707

NANPA records 4 assigned NXX blocks to rate center HOPLAND in area code 707, 0.5% 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. 4 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - CA (1), NEW CINGULAR WIRELESS PCS, LLC (1), PACIFIC BELL (1). The earliest assignment on record here is 2006-02-23 and the most recent 2019-07-12. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
