W MILFORD prefixes in area code 862

NANPA records 3 assigned NXX blocks to rate center W MILFORD in area code 862, 0.8% of the 391 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. 2 holders hold those blocks, the largest being ONVOY, LLC - NJ (2), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2021-04-14 and the most recent 2024-10-14. 3 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 304, 681, 973 – overlay codes cover the same geography, so a rate center is served by all of them.
