NORTHRIDGE prefixes in area code 747
NANPA records 19 assigned NXX blocks to rate center NORTHRIDGE in area code 747, 7.3% of the 260 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. 12 holders hold those blocks, the largest being FRACTEL, LLC (4), NEW CINGULAR WIRELESS PCS, LLC (3), T-MOBILE USA, INC. (3). The earliest assignment on record here is 2009-08-14 and the most recent 2026-08-07. 18 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 818 – overlay codes cover the same geography, so a rate center is served by all of them.
