How to search North Dakota business entities

Every business that operates legally in North Dakota files a public record with the North Dakota Secretary of State. That record names the entity, identifies its registered agent for service of process, and tracks every formal filing through dissolution. Those records are open to anyone — that is the legal definition of a public registry.

Corporate.AI is a free, structured front door to North Dakota's public business filings. We mirror the state's data, normalize it against records from 49 other jurisdictions, and add the cross-state intelligence (shared officers, shared registered agents, NAICS sector classification, beneficial-ownership signals) that a single-state portal cannot provide. Use the search above to look up any North Dakota entity by name, by primary filing number, or by officer.

For absolute freshness — same-day filings, formal certificates of good standing, certified document copies — you should also have the North Dakota SOS portal bookmarked. We link directly to it from this page.

North Dakota business entity search FAQ

How do I search North Dakota business entities?▶

Use the search box above to query Corporate.AI for any North Dakota-registered LLC, corporation, nonprofit, or partnership. You can also search directly at the North Dakota SOS's public registry portal. Corporate.AI consolidates North Dakota entity records with cross-state filings (foreign registrations, officer overlap, registered-agent networks) so a single search returns more context than the state portal alone.

Is North Dakota business entity search free?▶

Yes. Public North Dakota business filings are open records. Corporate.AI never charges to look up an entity, its registered agent, officers, or filing history. The North Dakota SOS also offers free public search; premium services (certified copies, certificates of good standing) typically cost $135 or more depending on document type.

What information is included in a North Dakota entity search?▶

Each North Dakota entity record on Corporate.AI includes the registered legal name, entity type (LLC, Corporation, LP, Nonprofit), formation date, current status, primary filing number assigned by the North Dakota SOS, registered agent (when published), officer roster (when published), and full filing history. We also surface entities that share officers, registered agents, or NAICS sector classifications across all 50 states.

How do I get a North Dakota certificate of good standing?▶

A certificate of good standing (sometimes called a certificate of existence or status certificate) must be issued by the North Dakota SOS directly — Corporate.AI does not issue official certificates. You can typically request one online from the North Dakota SOS for $34–$50 with same-day or 24-hour turnaround. The certificate confirms the entity is in good standing as of the issuance date.

How do I look up a registered agent in North Dakota?▶

Every North Dakota business entity is required to designate a registered agent — a person or company authorized to receive service of process at a North Dakota street address. Corporate.AI's registered-agent index lets you reverse-search: given an agent name, see every North Dakota entity that has designated them. This pattern is useful for due diligence, beneficial-ownership analysis, and competitive research. The North Dakota SOS's portal supports forward lookup (entity → agent) but typically not reverse lookup.

What's the difference between an LLC and a corporation in North Dakota?▶

A North Dakota LLC (limited liability company) is the most common entity type for small businesses — it offers liability protection with pass-through taxation and minimal corporate formalities. A North Dakota corporation (typically a C-corp or S-corp) is owned by shareholders, governed by a board, and is the standard vehicle for raising outside investment. Formation fees are similar — $135 for an LLC vs $100 for a corporation in North Dakota as of 2026 — but the tax, governance, and capital-raising profiles differ significantly.

How recent is the North Dakota business data on Corporate.AI?▶

North Dakota entity records on Corporate.AI are refreshed from the North Dakota SOS's public feed on the cadence the state publishes — daily, weekly, or monthly depending on jurisdiction. Each entity page displays a "last refreshed" timestamp so you can verify how recent the underlying record is. For absolute freshness, cross-check against the North Dakota SOS's live portal (linked above) before relying on a record for legal or contractual purposes.

Can I download North Dakota business entity data?▶

Yes. Corporate.AI's REST API and MCP server expose North Dakota entity records in machine-readable form for licensed use cases — KYC/AML programs, sales prospecting, journalism, academic research. Bulk downloads of the North Dakota SOS's underlying data are typically available directly from the state, sometimes free and sometimes for a fee. See our /api page for licensing terms.
