STCROIXBCH prefixes in area code 651

NANPA records 9 assigned NXX blocks to rate center STCROIXBCH in area code 651, 1.9% of the 474 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. 8 holders hold those blocks, the largest being QWEST CORPORATION (2), ONVOY, LLC - MN (1), TELEPORT COMMUNICATIONS AMERICA, LLC - MN (1). The earliest assignment on record here is 2014-10-28 and the most recent 2021-06-17. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
