FORTUNA prefixes in area code 707

NANPA records 5 assigned NXX blocks to rate center FORTUNA in area code 707, 0.6% 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 PACIFIC BELL (2), PEERLESS NETWORK OF CALIFORNIA, LLC - CA (1), LEVEL 3 COMMUNICATIONS, LLC - CA (1). The earliest assignment on record here is 2013-03-08 and the most recent 2018-12-04. 4 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, 660, 701 – overlay codes cover the same geography, so a rate center is served by all of them.
