CALIFON prefixes in area code 908

NANPA records 4 assigned NXX blocks to rate center CALIFON in area code 908, 0.6% of the 721 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. 4 holders hold those blocks, the largest being ONVOY, LLC - NJ (1), BANDWIDTH.COM CLEC, LLC - NJ (1), BRIGHTSPEED OF NEW JERSEY, INC. (1). The earliest assignment on record here is 2002-05-16 and the most recent 2022-01-24. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
