MARSHFIELD prefixes in area code 781

NANPA records 8 assigned NXX blocks to rate center MARSHFIELD in area code 781, 1.0% of the 769 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. 5 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (3), METROPCS, INC. (2), BANDWIDTH.COM CLEC, LLC - MA (1). The earliest assignment on record here is 2001-03-19 and the most recent 2021-09-23. 6 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 339, 417, 534, 715 – overlay codes cover the same geography, so a rate center is served by all of them.
