ARVIN prefixes in area code 661
NANPA records 22 assigned NXX blocks to rate center ARVIN in area code 661, 3.3% of the 674 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. 11 holders hold those blocks, the largest being T-MOBILE USA, INC. (8), U.S. TELEPACIFIC CORP. DBA TPX COMMUNICATIONS (2), ONVOY, LLC - CA (2). The earliest assignment on record here is 2002-01-16 and the most recent 2026-09-17. 21 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
