E DOUGLAS prefixes in area code 774

NANPA records 4 assigned NXX blocks to rate center E DOUGLAS in area code 774, 0.8% 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. 3 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MA (2), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1), PEERLESS NETWORK OF MASSACHUSETTS, LLC - MA (1). The earliest assignment on record here is 2001-07-06 and the most recent 2016-12-29. 4 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 508 – overlay codes cover the same geography, so a rate center is served by all of them.
