GREENWOOD prefixes in area code 317

NANPA records 22 assigned NXX blocks to rate center GREENWOOD in area code 317, 2.8% of the 786 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 INDIANA BELL TEL CO INC (11), PAETEC ITEL, LLC (3), BANDWIDTH.COM CLEC, LLC - IN (2). The earliest assignment on record here is 2005-10-04 and the most recent 2025-06-20. 14 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, 318, 402, 463 – overlay codes cover the same geography, so a rate center is served by all of them.
