HAZEN prefixes in area code 701

NANPA records 4 assigned NXX blocks to rate center HAZEN in area code 701, 0.5% 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. 2 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - ND (3), WEST RIVER TELECOMMUNICATIONS COOP. - ND (1). The earliest assignment on record here is 2004-06-10 and the most recent 2004-06-10. 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 582, 814, 870 – overlay codes cover the same geography, so a rate center is served by all of them.
