HUBBARDSTN prefixes in area code 989

NANPA records 4 assigned NXX blocks to rate center HUBBARDSTN in area code 989, 0.6% of the 723 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 (2), INTERACTIVE SERVICES NETWORK, INC. (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-11-14 and the most recent 2001-11-29. 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 351, 978 – overlay codes cover the same geography, so a rate center is served by all of them.
