GREENFIELD prefixes in area code 413
NANPA records 20 assigned NXX blocks to rate center GREENFIELD in area code 413, 3.3% of the 605 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. 8 holders hold those blocks, the largest being PAETEC ITEL, LLC (4), VERIZON NEW ENGLAND INC. (4), OMNIPOINT MIAMI E LICENSE, LLC (3). The earliest assignment on record here is 2022-01-27 and the most recent 2026-10-13. 16 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, 317, 417, 463 – overlay codes cover the same geography, so a rate center is served by all of them.
