BELFIELD prefixes in area code 701

NANPA records 5 assigned NXX blocks to rate center BELFIELD 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. 4 holders hold those blocks, the largest being ONVOY, LLC - ND (2), CONSOLIDATED COMMUNICATIONS NETWORKS, INC. - ND (1), QWEST CORPORATION (1). The earliest assignment on record here is 2014-06-04 and the most recent 2021-04-26. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
