106 moving companies are federally registered in South Dakota, from national van lines to one-truck local crews, with the largest cluster in Sioux Falls (36 companies). Every one of them has a public federal record: registration, fleet size, and four years of consumer complaints. This page lists them all; click any company to open its full MoverAudit report.
Before you shortlist anyone in South Dakota, know the local landscape: 0 of these companies are registered as brokers only, meaning they resell your move to a carrier you never chose, and 8 have zero trucks on file with FMCSA. At the other end, the largest registered fleet in the state belongs to Furniture Mart Usa, Inc. with 117 power units. Fleet size does not equal honesty, but a company promising statewide next-day service with one truck deserves a hard look at its report.
Start with the record, not the reviews. Star ratings can be bought and buried; the federal complaint database cannot. Open the MoverAudit report for every company on your shortlist and check three things: is it a carrier or a broker, does the fleet size match its promises, and what do the complaint categories say about how it fails. A "Loss and Damage" complaint at a large van line is ordinary friction; a "Hostage Goods" complaint anywhere is a walk-away signal.
For interstate moves (leaving South Dakota), the company must hold federal household goods authority and print its USDOT number on the quote. Verify that the number on the paperwork matches the company name here: a borrowed or mismatched USDOT number is one of the oldest tricks in moving fraud.
For moves within South Dakota, state rules apply on top of federal registration, and complaints also go to the state's consumer protection office. The habits stay the same: written binding estimate after a real survey, small traceable deposit, and the truck does not get loaded until the paperwork matches the company you actually vetted.
