GREENWOOD prefixes in area code 821

NANPA records 12 assigned NXX blocks to rate center GREENWOOD in area code 821, 28.6% of the 42 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. 1 holder holds those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (12). The earliest assignment on record here is 2024-12-06 and the most recent 2026-04-17. 12 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.
