HOPKINTON prefixes in area code 774

NANPA records 6 assigned NXX blocks to rate center HOPKINTON in area code 774, 1.1% 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. 5 holders hold those blocks, the largest being METROPCS, INC. (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MA (1), LEVEL 3 COMMUNICATIONS, LLC - MA (1). The earliest assignment on record here is 2001-03-19 and the most recent 2017-09-07. 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 508, 563 – overlay codes cover the same geography, so a rate center is served by all of them.
