MILFORD prefixes in area code 774

NANPA records 8 assigned NXX blocks to rate center MILFORD in area code 774, 1.5% 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. 8 holders hold those blocks, the largest being PAETEC ITEL, LLC (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1), BANDWIDTH.COM CLEC, LLC - MA (1). The earliest assignment on record here is 2001-03-20 and the most recent 2023-10-20. 8 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 203, 272, 302, 402 – overlay codes cover the same geography, so a rate center is served by all of them.
