TORRANCE prefixes in area code 310
NANPA records 33 assigned NXX blocks to rate center TORRANCE in area code 310, 4.2% of the 786 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 PACIFIC BELL (14), T-MOBILE USA, INC. (5), NEW CINGULAR WIRELESS PCS, LLC (3). The earliest assignment on record here is 2001-05-03 and the most recent 2005-09-29. 21 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 424 – overlay codes cover the same geography, so a rate center is served by all of them.
