EASTBOSTON prefixes in area code 617

NANPA records 15 assigned NXX blocks to rate center EASTBOSTON in area code 617, 2.0% of the 768 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. 7 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (5), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3), METROPCS, INC. (2). The earliest assignment on record here is 2001-02-14 and the most recent 2001-02-14. 11 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 857 – overlay codes cover the same geography, so a rate center is served by all of them.
