WHITEHALL prefixes in area code 231
NANPA records 5 assigned NXX blocks to rate center WHITEHALL in area code 231, 0.9% of the 572 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. - MI (3), CHARTER IP ENABLED SERVICES, LLC (1), ONVOY, LLCV - MI (1). The earliest assignment on record here is 2010-07-30 and the most recent 2019-10-10. 4 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 406, 518, 534, 715 – overlay codes cover the same geography, so a rate center is served by all of them.
