MOBRIDGE prefixes in area code 605
NANPA records 5 assigned NXX blocks to rate center MOBRIDGE in area code 605, 0.7% of the 745 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 NEW CINGULAR WIRELESS PCS, LLC - IL (3), WEST RIVER TELECOMMUNICATIONS COOP. - SD (1), WEST RIVER TELECOMMUNICATIONS COOP (MOBRIDGE) - SD (1). The earliest assignment on record here is 2003-01-21 and the most recent 2022-05-20. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
