MARLTON prefixes in area code 856

NANPA records 21 assigned NXX blocks to rate center MARLTON in area code 856, 3.1% of the 676 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. 8 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (7), PAETEC ITEL, LLC (4), LEVEL 3 COMMUNICATIONS, LLC - NJ (3). The earliest assignment on record here is 2001-03-28 and the most recent 2001-10-04. 15 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
