PSDN PSDN prefixes in area code 626
NANPA records 128 assigned NXX blocks to rate center PSDN PSDN in area code 626, 17.4% of the 737 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. 21 holders hold those blocks, the largest being PACIFIC BELL (42), NEW CINGULAR WIRELESS PCS, LLC (18), T-MOBILE USA, INC. (17). The earliest assignment on record here is 2001-05-18 and the most recent 2025-11-20. 73 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
