BROCKTON prefixes in area code 774

NANPA records 28 assigned NXX blocks to rate center BROCKTON in area code 774, 5.4% of the 522 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. 11 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - DC (7), OMNIPOINT MIAMI E LICENSE, LLC (6), METROPCS, INC. (4). The earliest assignment on record here is 2001-03-20 and the most recent 2024-05-09. 28 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 406, 508 – overlay codes cover the same geography, so a rate center is served by all of them.
