DERRY prefixes in area code 603
NANPA records 29 assigned NXX blocks to rate center DERRY 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. 9 holders hold those blocks, the largest being CONSOLIDATED COMM OF NO. NEW ENGLAND-NH (8), OMNIPOINT MIAMI E LICENSE, LLC (5), NEW CINGULAR WIRELESS PCS, LLC - DC (5). The earliest assignment on record here is 2001-05-03 and the most recent 2022-09-13. 21 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 724, 878 – overlay codes cover the same geography, so a rate center is served by all of them.
