Most Minnesota business entity information, including entity name, type, number, and formation date, is available through the Minnesota SOS Business Filings portal. This free database provides immediate access to the four key details you need for onboarding, compliance, or business transactions.

Below, we'll walk you through how to search the Minnesota database and what format each data point takes. Bank and insurance corporation details are not available through the portal; those must be obtained from the Minnesota Department of Commerce.

Summary table: finding your Minnesota entity information

How to search for Minnesota business entities

Access the Minnesota business entity search to look up any registered business. The portal offers two search modes via tabs above the search box: Business Name and File Number.

Minnesota's system supports partial matches, and the SOS help page recommends typing only a portion of the business name for best results. You can refine searches using "Begins With" or "Contains" scope, filter by Active or Inactive status, and choose whether to include prior names. Click "Details" next to a result to open the Business Record Details page with your entity number, formation date, registered agent information in Minnesota, and Filing History.

What you'll see in search results

• Legal entity name (exact spelling and punctuation)

• Entity type (LLC requirements and formation in Minnesota, Corporation, LP, LLP, Nonprofit Corporation, Cooperative)

• File Number (Minnesota's primary entity identifier)

• Formation/file date

• Current status (Active, Inactive, Dissolved)

• Name type designation (Current Legal, Former Legal, or Assumed)

How to find your entity number in Minnesota

Your Minnesota entity number is labeled "File Number" in the MBLS portal and "Original Filing Number" in the state's database schema, per the SOS Bulk Data Implementation Guide. It follows a long numeric format like 448230000028 and was assigned by the Minnesota Secretary of State at formation.

You can locate your File Number in three places:

• Minnesota business search: displayed on the entity details page, labeled "File Number"

• Certificate of Formation, Organization, or Incorporation: usually at the top of the document, often labeled "Original Filing Number"

• Annual renewal filings in Minnesota and state correspondence: appears on all official SOS documents as your account identifier

File numbers are long numeric identifiers, commonly 12 digits. In practice, newer entities generally have higher file numbers, though the Secretary of State does not publish details on the numbering pattern.

How to find your entity type in Minnesota

Minnesota recognizes several common entity types, including Business Corporations, Nonprofit Corporations, LLCs, LLPs, LPs, Cooperatives, and Public Benefit Corporations, along with additional filing categories such as assumed names and cooperative associations.

You can find your entity type in three places:

• Minnesota business search: displayed under the "Business Type" column and on the entity details page

• Certificate of Formation, Organization, or Incorporation: stated at the top of your formation document

• Annual renewal filings: listed in the entity information section; the entity type cannot be changed without a formal amendment

Minnesota also recognizes sub-types that are not separate filing categories. Professional Corporations (PCs) are formed as Business Corporations under Minn. Stat. Ch. 302A with required language per Ch. 319B. Professional LLCs file as LLCs but may use "PLLC" in their name. Limited Liability Limited Partnerships (LLLPs) are an election within the LP filing category, not a separately filed entity type.

How to find your formation date in Minnesota

Your formation date, when the Minnesota Secretary of State officially filed and approved your business entity, appears in business search results and on your Certificate of Formation, Organization, or Incorporation.

You can find your formation date in three places:

• Minnesota business search: listed as "Filing Date" in search results and entity details, formatted MM/DD/YYYY

• Certificate of Formation, Organization, or Incorporation: at the top of the document with the SOS filing stamp

• Annual renewal confirmations: references the original filing date and is used to calculate renewal due dates

Formation date vs. effective date

For most entity types, formation occurs when the Secretary of State files and accepts the documents. Per Minn. Stat. § 322C.0201, an LLC is formed when articles of organization are filed with the SOS accompanied by payment.

Minnesota does provide delayed effective date provisions for certain entity types, including a dedicated provision at Minn. Stat. § 302A.153 for business corporations. If a delayed effective date was designated at filing, the legal formation date may differ from the SOS processing date, which can be material for determining the start of legal existence, contract authority, and tax year beginning. For most onboarding purposes, the "Filing Date" shown in the business search is the date you will use.
