STURGIS prefixes in area code 605

NANPA records 9 assigned NXX blocks to rate center STURGIS in area code 605, 1.2% 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. 6 holders hold those blocks, the largest being QWEST CORPORATION (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - SD (2), ONVOY, LLC - SD (2). The earliest assignment on record here is 2003-03-18 and the most recent 2022-11-23. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 269, 270 – overlay codes cover the same geography, so a rate center is served by all of them.
