RAMSEY prefixes in area code 201

NANPA records 30 assigned NXX blocks to rate center RAMSEY in area code 201, 3.9% of the 779 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. 11 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (8), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NJ (6), NEW CINGULAR WIRELESS PCS, LLC - DC (5). The earliest assignment on record here is 2001-03-23 and the most recent 2016-02-29. 17 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 551, 618, 812, 930 – overlay codes cover the same geography, so a rate center is served by all of them.
