SADLBK VLY prefixes in area code 949
NANPA records 148 assigned NXX blocks to rate center SADLBK VLY in area code 949, 19.8% of the 747 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. 26 holders hold those blocks, the largest being PACIFIC BELL (48), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (19), ONVOY, LLC - CA (10). The earliest assignment on record here is 2001-02-22 and the most recent 2026-07-24. 100 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
