MAYNARD prefixes in area code 978

NANPA records 18 assigned NXX blocks to rate center MAYNARD in area code 978, 2.3% of the 773 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 PAETEC ITEL, LLC (3), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3), LEVEL 3 COMMUNICATIONS, LLC - MA (3). The earliest assignment on record here is 2001-01-08 and the most recent 2002-07-09. 16 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 320, 327, 563, 870 – overlay codes cover the same geography, so a rate center is served by all of them.
