GREENWOOD prefixes in area code 479

NANPA records 6 assigned NXX blocks to rate center GREENWOOD in area code 479, 1.1% of the 569 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 NEW CINGULAR WIRELESS PCS, LLC - IL (2), T-MOBILE USA, INC. (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AR (1). The earliest assignment on record here is 2002-08-27 and the most recent 2023-02-03. 5 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 302, 317, 318, 402 – overlay codes cover the same geography, so a rate center is served by all of them.
