SOMIS prefixes in area code 805

NANPA records 4 assigned NXX blocks to rate center SOMIS in area code 805, 0.5% of the 786 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 U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (1), FRONTIER CALIFORNIA INC. (1), BANDWIDTH.COM CLEC, LLC - CA (1). The earliest assignment on record here is 2008-09-11 and the most recent 2018-03-26. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
