MANCHESTER prefixes in area code 603

NANPA records 80 assigned NXX blocks to rate center MANCHESTER in area code 603, 10.6% 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. 23 holders hold those blocks, the largest being CONSOLIDATED COMM OF NO. NEW ENGLAND-NH (31), OMNIPOINT MIAMI E LICENSE, LLC (7), NEW CINGULAR WIRELESS PCS, LLC - DC (6). The earliest assignment on record here is 2001-05-18 and the most recent 2022-01-13. 45 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 217, 223, 326, 351 – overlay codes cover the same geography, so a rate center is served by all of them.
