DELAWARE prefixes in area code 740

NANPA records 19 assigned NXX blocks to rate center DELAWARE in area code 740, 2.4% of the 786 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. 7 holders hold those blocks, the largest being FRONTIER NORTH, INC. - OH (5), AERIAL COMMUNICATIONS, INC. (4), LEVEL 3 COMMUNICATIONS, LLC - OH (3). The earliest assignment on record here is 2001-05-08 and the most recent 2023-12-14. 13 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 220, 918 – overlay codes cover the same geography, so a rate center is served by all of them.
