THOMPSON prefixes in area code 701

NANPA records 3 assigned NXX blocks to rate center THOMPSON in area code 701, 0.4% 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. 3 holders hold those blocks, the largest being MIDCONTINENT COMMUNICATIONS - ND (1), QWEST CORPORATION (1), ONVOY, LLC - ND (1). The earliest assignment on record here is 2007-01-19 and the most recent 2019-08-12. 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 codes 272, 435, 440, 570 – overlay codes cover the same geography, so a rate center is served by all of them.
