BISMARCK prefixes in area code 701
NANPA records 55 assigned NXX blocks to rate center BISMARCK in area code 701, 7.4% of the 743 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. 27 holders hold those blocks, the largest being QWEST CORPORATION (12), NEW CINGULAR WIRELESS PCS, LLC - IL (7), ONVOY, LLC - ND (5). The earliest assignment on record here is 2001-04-25 and the most recent 2025-07-15. 36 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 217, 447, 501, 573 – overlay codes cover the same geography, so a rate center is served by all of them.
