MILFORD prefixes in area code 203
NANPA records 14 assigned NXX blocks to rate center MILFORD in area code 203, 1.8% of the 784 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. 6 holders hold those blocks, the largest being SOUTHERN NEW ENGLAND TELCO DBA FRONTIER COMM OF CT (7), CABLEVISION LIGHTPATH, INC. - CT (2), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2010-07-13 and the most recent 2010-07-13. 7 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 272, 302, 402, 435 – overlay codes cover the same geography, so a rate center is served by all of them.
