SNJS SOUTH prefixes in area code 669

NANPA records 33 assigned NXX blocks to rate center SNJS SOUTH in area code 669, 13.9% of the 238 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. 15 holders hold those blocks, the largest being T-MOBILE USA, INC. (7), ONVOY, LLC - CA (6), FRACTEL, LLC (5). The earliest assignment on record here is 2014-03-24 and the most recent 2025-02-21. 33 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 408 – overlay codes cover the same geography, so a rate center is served by all of them.
