MALDEN prefixes in area code 781

NANPA records 22 assigned NXX blocks to rate center MALDEN in area code 781, 2.9% 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. 11 holders hold those blocks, the largest being VERIZON NEW ENGLAND INC. (7), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (4), PAETEC ITEL, LLC (3). The earliest assignment on record here is 2001-03-19 and the most recent 2002-07-30. 17 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, 573, 617 – overlay codes cover the same geography, so a rate center is served by all of them.
