MORRISTOWN prefixes in area code 201

NANPA records 22 assigned NXX blocks to rate center MORRISTOWN in area code 201, 2.8% 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. 3 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (14), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - NJ (7), OMNIPOINT COMMUNICATIONS, INC. - NJ (1). The earliest assignment on record here is 2001-04-13 and the most recent 2001-04-13. 14 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 315, 423, 507, 680 – overlay codes cover the same geography, so a rate center is served by all of them.
