NORWOOD prefixes in area code 704

NANPA records 4 assigned NXX blocks to rate center NORWOOD in area code 704, 0.5% of the 782 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. 4 holders hold those blocks, the largest being MCIMETRO ACCESS TRANSMISSION SERVICES LLC - NC (1), LEVEL 3 COMMUNICATIONS, LLC - NC (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2006-03-23 and the most recent 2006-10-03. 2 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 315, 339, 417, 781 – overlay codes cover the same geography, so a rate center is served by all of them.
