SOUTHRIVER prefixes in area code 732

NANPA records 24 assigned NXX blocks to rate center SOUTHRIVER in area code 732, 3.1% of the 780 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. 9 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (13), LEVEL 3 COMMUNICATIONS, LLC - NJ (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (2). The earliest assignment on record here is 2001-01-16 and the most recent 2022-08-01. 16 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 codes 848, 910 – overlay codes cover the same geography, so a rate center is served by all of them.
