HAMILTON prefixes in area code 978

NANPA records 6 assigned NXX blocks to rate center HAMILTON in area code 978, 0.8% of the 773 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 LEVEL 3 COMMUNICATIONS, LLC - MA (2), ONVOY, LLC - MA (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2001-07-27 and the most recent 2018-02-05. 5 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 205, 217, 252, 254 – overlay codes cover the same geography, so a rate center is served by all of them.
