WOODSIDE prefixes in area code 650

NANPA records 14 assigned NXX blocks to rate center WOODSIDE in area code 650, 2.0% 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. 11 holders hold those blocks, the largest being U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (2), LEVEL 3 COMMUNICATIONS, LLC - CA (2), PACIFIC BELL (2). The earliest assignment on record here is 2022-01-10 and the most recent 2023-12-29. 13 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
