SNFN SPLV prefixes in area code 747

NANPA records 9 assigned NXX blocks to rate center SNFN SPLV in area code 747, 3.5% of the 260 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. 6 holders hold those blocks, the largest being ONVOY, LLC - CA (3), BANDWIDTH.COM CLEC, LLC - CA (2), NEW CINGULAR WIRELESS PCS, LLC (1). The earliest assignment on record here is 2015-10-02 and the most recent 2026-07-28. 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 818 – overlay codes cover the same geography, so a rate center is served by all of them.
