SIOUX CITY prefixes in area code 712
NANPA records 73 assigned NXX blocks to rate center SIOUX CITY in area code 712, 11.5% 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. 29 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (14), QWEST CORPORATION (13), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IA (8). The earliest assignment on record here is 2001-03-07 and the most recent 2026-08-05. 52 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
