South Dakota Business Entity Search | SD Secretary of State

Quick Answer

Use the South Dakota Secretary of State Business Services portal to run a South Dakota entity search by business name or Secretary of State Business ID. For name research, enter the proposed wording, choose Starts With or Contains, and compare active and similar records before filing. A clear search is only preliminary; final acceptance happens during the state’s filing or reservation review.

How to Search South Dakota Business Entity Records

The official registry of business records is maintained by the Business Services Division of the South Dakota Secretary of State. You can search the public database for free online.

Go to the official South Dakota Business Search page to begin.

South Dakota Business Information Search portal landing page — Navigate to the official South Dakota Secretary of State Business Services search page.

Enter Your Search Parameters

Type your target business name into the Search Name text box. Refine your query by utilizing the available search options:

Choose Starts With or Contains to define how the search phrase matches the registered entity name.
Check the Active Entities Only checkbox if you want to restrict results to active businesses only (leave this unmarked to view all records, including dissolved or cancelled entities).

Click the Search button to execute the query.

If the search results return no close matches for South Dakota, treat that as a preliminary screening signal only. Verify the name in the official state database, and wait for the state filing or name-reservation review before treating the name as accepted.

How to Interpret South Dakota Results

South Dakota results can include the entity name, Business ID, status, registered agent, and document images. Treat the list view as a starting point. Open the detail page before relying on the result, especially when two names differ only by entity ending, punctuation, or word order.

Use Active Entities Only when you want a narrow conflict check, but run an unfiltered search when you are researching a company history or a proposed name with close variants. Cancelled, dissolved, or withdrawn entities may still explain why a name appears in the database, and document images can show older filings that are not obvious from the result list.

South Dakota Business Name and Filing Notes

South Dakota’s business portal combines entity search, online filings, document images, and annual report maintenance. Keep these follow-up items separate from the initial public search:

LLC Filing Fees: Filing the Articles of Organization online for a domestic South Dakota LLC costs $150. Paper filings cost $165 (includes a $15 paper filing fee).
Name Reservation: You can reserve a business name for up to 120 days by filing a Name Reservation application. The fee is $25.
Annual Reports: South Dakota LLCs are required to file an annual report each year. Reports are due on the first day of the anniversary month of formation. The filing fee is $55 online or $70 by mail.
Foreign LLCs: To register an out-of-state LLC to do business in South Dakota, you must file an Application for Certificate of Authority. The filing fee is $750 online or $765 by mail.

Common Mistakes

Leaving Active Entities Only on for research: That filter is useful for conflict checks, but it can hide inactive records and filing history.
Skipping document images: South Dakota detail pages can link to filed PDFs. Use those documents when the result list does not explain a status or name change.
Searching with the legal ending first: Search the distinctive words before trying LLC, Inc., Corp., or other designators.
Missing the anniversary-month report deadline: South Dakota annual reports are due on the first day of the anniversary month.
Treating a clean search as approval: The search is preliminary. The Secretary of State decides name acceptance when it reviews the filing or reservation.
