SAUKCENTRE prefixes in area code 320

NANPA records 6 assigned NXX blocks to rate center SAUKCENTRE in area code 320, 1.2% of the 511 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. 6 holders hold those blocks, the largest being MAINSTREET COMMUNICATIONS, LL. (1), QWEST CORPORATION (1), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MN (1). The earliest assignment on record here is 2003-04-30 and the most recent 2020-06-17. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
