SNFN SNFN prefixes in area code 747

NANPA records 16 assigned NXX blocks to rate center SNFN SNFN in area code 747, 6.2% 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. 10 holders hold those blocks, the largest being ONVOY, LLC - CA (4), T-MOBILE USA, INC. (2), BANDWIDTH.COM CLEC, LLC - CA (2). The earliest assignment on record here is 2013-03-08 and the most recent 2026-08-07. 16 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.

The holder is who received the block from the numbering administrator. It is not necessarily the carrier serving a given number: numbers move with their owners, and a pooled block is shared.
