AZUSA prefixes in area code 626
NANPA records 49 assigned NXX blocks to rate center AZUSA in area code 626, 6.6% 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. 17 holders hold those blocks, the largest being FRONTIER CALIFORNIA INC. (10), NEW CINGULAR WIRELESS PCS, LLC (9), T-MOBILE USA, INC. (5). The earliest assignment on record here is 2001-08-22 and the most recent 2026-08-05. 40 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
