MILFORD prefixes in area code 302
NANPA records 34 assigned NXX blocks to rate center MILFORD in area code 302, 5.2% 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. 13 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (18), VERIZON DELAWARE, INC. (3), LEVEL 3 COMMUNICATIONS, LLC - DE (2). The earliest assignment on record here is 2001-03-19 and the most recent 2026-08-24. 28 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 203, 272, 402, 435 – overlay codes cover the same geography, so a rate center is served by all of them.
