REDWOOD CY prefixes in area code 650
NANPA records 65 assigned NXX blocks to rate center REDWOOD CY in area code 650, 9.1% of the 717 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 PACIFIC BELL (28), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (7), ONVOY, LLC - CA (6). The earliest assignment on record here is 2001-01-25 and the most recent 2026-08-21. 42 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
