RAPID CITY prefixes in area code 605
NANPA records 50 assigned NXX blocks to rate center RAPID CITY in area code 605, 6.7% 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. 13 holders hold those blocks, the largest being QWEST CORPORATION (16), NEW CINGULAR WIRELESS PCS, LLC - IL (8), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SD (7). The earliest assignment on record here is 2001-01-16 and the most recent 2026-05-08. 29 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
