VALLEY SPG prefixes in area code 209

NANPA records 4 assigned NXX blocks to rate center VALLEY SPG in area code 209, 0.5% of the 784 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. 4 holders hold those blocks, the largest being ONVOY, LLC - CA (1), PACIFIC BELL (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (1). The earliest assignment on record here is 2017-11-10 and the most recent 2017-11-10. 4 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 codes 350, 605 – overlay codes cover the same geography, so a rate center is served by all of them.
