CONCORD prefixes in area code 978

NANPA records 30 assigned NXX blocks to rate center CONCORD in area code 978, 3.9% 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. 12 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - MA (9), VERIZON NEW ENGLAND INC. (6), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3). The earliest assignment on record here is 2001-01-09 and the most recent 2017-09-01. 22 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 217, 434, 470, 517 – overlay codes cover the same geography, so a rate center is served by all of them.
