HOUGHTON prefixes in area code 906

NANPA records 13 assigned NXX blocks to rate center HOUGHTON in area code 906, 3.6% of the 360 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. 8 holders hold those blocks, the largest being MICHIGAN BELL TEL CO (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MI (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2003-07-28 and the most recent 2024-02-21. 7 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 319, 605 – overlay codes cover the same geography, so a rate center is served by all of them.
