PSBG WEST prefixes in area code 925
NANPA records 10 assigned NXX blocks to rate center PSBG WEST in area code 925, 1.6% of the 640 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. 7 holders hold those blocks, the largest being PACIFIC BELL (3), ONVOY, LLC - CA (2), LEVEL 3 COMMUNICATIONS, LLC - CA (1). The earliest assignment on record here is 2001-05-21 and the most recent 2026-09-14. 10 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
