PIERRE prefixes in area code 605

NANPA records 15 assigned NXX blocks to rate center PIERRE in area code 605, 2.0% 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. 8 holders hold those blocks, the largest being QWEST CORPORATION (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SD (3), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2001-02-09 and the most recent 2021-10-07. 9 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
