MOORESTOWN prefixes in area code 231

NANPA records 4 assigned NXX blocks to rate center MOORESTOWN in area code 231, 0.7% of the 572 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (2), BRIGHTSPEED OF MICHIGAN, LLC (1), INTERACTIVE SERVICES NETWORK, INC. (1). The earliest assignment on record here is 2003-07-29 and the most recent 2011-04-29. 2 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 609, 856 – overlay codes cover the same geography, so a rate center is served by all of them.
