DOVER prefixes in area code 603
NANPA records 29 assigned NXX blocks to rate center DOVER in area code 603, 3.9% of the 752 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. 14 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (6), CONSOLIDATED COMM OF NO. NEW ENGLAND-NH (5), PAETEC ITEL, LLC (4). The earliest assignment on record here is 2001-03-16 and the most recent 2023-08-31. 19 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.
