DOVER prefixes in area code 973

NANPA records 16 assigned NXX blocks to rate center DOVER in area code 973, 2.1% 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. 6 holders hold those blocks, the largest being VERIZON NEW JERSEY, INC. (7), METROPCS, INC. (3), LEVEL 3 COMMUNICATIONS, LLC - NJ (2). The earliest assignment on record here is 2001-07-18 and the most recent 2006-03-24. 9 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 223, 302, 405, 479 – overlay codes cover the same geography, so a rate center is served by all of them.
