GRAFTON prefixes in area code 701

NANPA records 5 assigned NXX blocks to rate center GRAFTON in area code 701, 0.7% 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. 5 holders hold those blocks, the largest being QWEST CORPORATION (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), MIDCONTINENT COMMUNICATIONS - ND (1). The earliest assignment on record here is 2007-05-14 and the most recent 2021-01-28. 5 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 304, 402, 440, 508 – overlay codes cover the same geography, so a rate center is served by all of them.
