NEW CASTLE prefixes in area code 302
NANPA records 42 assigned NXX blocks to rate center NEW CASTLE in area code 302, 6.4% 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. 11 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (14), VERIZON DELAWARE, INC. (8), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (5). The earliest assignment on record here is 2001-03-09 and the most recent 2026-05-05. 25 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 540, 724, 765, 878 – overlay codes cover the same geography, so a rate center is served by all of them.
