MILFORD prefixes in area code 908

NANPA records 10 assigned NXX blocks to rate center MILFORD in area code 908, 1.4% of the 721 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 LEVEL 3 COMMUNICATIONS, LLC - NJ (5), TELEPORT COMMUNICATIONS AMERICA, LLC - NJ (1), MONMOUTH TELEPHONE AND TELEGRAPH, INC. - NJ (1). The earliest assignment on record here is 2002-02-07 and the most recent 2002-06-04. 10 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.
