PLYMOUTH prefixes in area code 574

NANPA records 16 assigned NXX blocks to rate center PLYMOUTH in area code 574, 4.0% of the 403 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. 12 holders hold those blocks, the largest being BRIGHTSPEED OF INDIANA, LLC (4), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (2), BANDWIDTH.COM CLEC, LLC - IN (1). The earliest assignment on record here is 2001-08-09 and the most recent 2025-01-23. 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 207, 209, 252, 272 – overlay codes cover the same geography, so a rate center is served by all of them.
