Questions
How many trucking companies are in South Dakota?
CarrierScrub's dataset covers every carrier in FMCSA's Licensing & Insurance registry -- about 1.68 million nationally -- plus carriers registered through Motus since, as of CarrierScrub's last import, so the South Dakota counts above are the complete set on file at that date. A carrier's verdict uses its current Motus record where FMCSA has one, and otherwise the legacy file, which FMCSA stopped updating on 14 May 2026. Most registrations in that registry are dormant, so the GO/CAUTION/STOP split counts only carriers holding active operating authority. For FMCSA's own record of a single carrier, search their SAFER Company Snapshot.
Are these all the trucking companies in South Dakota?
No. The counts above cover every South Dakota carrier on file at CarrierScrub's last import, but the list on this page is a short sample of carriers with a GO verdict, not all of them. Run any South Dakota carrier's USDOT or MC number through the free lookup directly; it isn't limited to this list.
How do I check if a specific South Dakota carrier has an active DOT number?
Use the DOT number status check -- enter any USDOT number, South Dakota or otherwise, and get a dated GO/CAUTION/STOP built from FMCSA's operating-authority and insurance filings, free, no account.
How often is this data updated?
The dataset is updated from FMCSA's open data in periodic imports, and a lookup refreshes a carrier from FMCSA when its stored record is more than a day old. A carrier's verdict uses its current FMCSA Motus record where one exists, and otherwise FMCSA's legacy file, which FMCSA stopped updating on 14 May 2026. Every carrier result shows which record it used and that record's date.
Does South Dakota require a USDOT number for intrastate carriers?
South Dakota is not on FMCSA's list of states that require intrastate carriers to obtain a USDOT number, so a carrier operating only within South Dakota may not have one. A carrier that crosses state lines falls under the federal rules regardless. For South Dakota's own intrastate registration, FMCSA's advice is to check with the responsible state agency.
