SIOUX CTR prefixes in area code 712
NANPA records 4 assigned NXX blocks to rate center SIOUX CTR in area code 712, 0.6% of the 633 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 (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (1), MUTUAL TEL. CO. (1). The earliest assignment on record here is 2007-03-28 and the most recent 2007-03-28. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
