KEANSBURG prefixes in area code 848

NANPA records 3 assigned NXX blocks to rate center KEANSBURG in area code 848, 1.0% of the 291 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. 3 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - NJ (1), ONVOY, LLC - NJ (1), CABLEVISION LIGHTPATH, INC. - NJ (1). The earliest assignment on record here is 2015-05-07 and the most recent 2023-11-07. 3 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 732 – overlay codes cover the same geography, so a rate center is served by all of them.
