DOVER prefixes in area code 302

NANPA records 49 assigned NXX blocks to rate center DOVER in area code 302, 7.5% of the 656 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. 15 holders hold those blocks, the largest being VERIZON DELAWARE, INC. (14), OMNIPOINT COMMUNICATIONS ENTERPRISES, LP (12), LEVEL 3 COMMUNICATIONS, LLC - DE (5). The earliest assignment on record here is 2001-03-09 and the most recent 2026-02-24. 36 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, 405, 479, 508 – overlay codes cover the same geography, so a rate center is served by all of them.
