BRAINTREE prefixes in area code 781

NANPA records 31 assigned NXX blocks to rate center BRAINTREE in area code 781, 4.0% 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. 9 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (8), OMNIPOINT MIAMI E LICENSE, LLC (7), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (4). The earliest assignment on record here is 2001-02-23 and the most recent 2021-12-03. 27 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 code 339 – overlay codes cover the same geography, so a rate center is served by all of them.
