DORCHESTER prefixes in area code 617
NANPA records 22 assigned NXX blocks to rate center DORCHESTER in area code 617, 2.9% 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. 8 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (11), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (4), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2024-02-09 and the most recent 2024-02-09. 12 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 402, 430, 531, 534 – overlay codes cover the same geography, so a rate center is served by all of them.
