SNJS WEST prefixes in area code 669

NANPA records 52 assigned NXX blocks to rate center SNJS WEST in area code 669, 21.8% 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. 16 holders hold those blocks, the largest being ONVOY, LLC - CA (12), TELEPORT COMMUNICATIONS AMERICA, LLC - CA (8), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (6). The earliest assignment on record here is 2012-11-02 and the most recent 2026-06-26. 52 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.
