WESTMILTON prefixes in area code 937
NANPA records 3 assigned NXX blocks to rate center WESTMILTON in area code 937, 0.4% of the 781 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. 3 holders hold those blocks, the largest being FRONTIER NORTH, INC. - OH (1), LEVEL 3 COMMUNICATIONS, LLC - OH (1), ONVOY, LLC - OH (1). The earliest assignment on record here is 2005-02-23 and the most recent 2026-10-12. 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 code 326 – overlay codes cover the same geography, so a rate center is served by all of them.
