DEDHAM prefixes in area code 781
NANPA records 35 assigned NXX blocks to rate center DEDHAM in area code 781, 4.6% of the 769 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. 12 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (10), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MA (5), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (4). The earliest assignment on record here is 2001-01-16 and the most recent 2021-12-03. 30 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 339, 617, 712 – overlay codes cover the same geography, so a rate center is served by all of them.
