SNFN SPLV prefixes in area code 818

NANPA records 15 assigned NXX blocks to rate center SNFN SPLV in area code 818, 1.9% of the 781 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. 8 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (8), PACIFIC BELL (COMPETITIVE) (1), METROPCS NETWORKS, LLC (1). The earliest assignment on record here is 2007-03-21 and the most recent 2017-04-14. 9 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 747 – overlay codes cover the same geography, so a rate center is served by all of them.
