How to Do a North Dakota LLC Name Search (2026 Guide)

Last Updated April 30, 2026 by the LLCForge Editorial Team. Verified against current state filing data and official Secretary of State sources.

Before you file Articles of Organization in North Dakota, your LLC name has to clear the Secretary of State’s distinguishability check. You’ll run that check yourself at firststop.sos.nd.gov, the state’s business records portal. A name isn’t yours until your formation document is approved, which typically takes a few business days for online filings. Pick a name that’s already taken and your filing gets rejected, costing you time and forcing a refile.

How to Search North Dakota LLC Names: Step-by-Step

1. Open the FirstStop business portal

Go to firststop.sos.nd.gov. This is the North Dakota Secretary of State’s online filing and search system. You don’t need an account to run a name search, but you’ll want one if you plan to file or reserve a name afterward.

Click “Search” from the main menu. The portal handles all entity types in one database, so your LLC name needs to clear against corporations, partnerships, trade names, and other LLCs.

2. Run a broad name search first

Pick “Business Search” and enter only the distinctive part of your proposed name. If you want “Red River Logistics LLC,” search “Red River Logistics” without the designator. Designators like LLC and Inc. don’t count toward distinguishability, so searching with them gives you a false sense of security.

Review every match. North Dakota’s distinguishability standard means a name like “Red River Logistic” (singular) or “Red River Logistics Co.” can still block your filing, depending on the examiner’s call.

3. Check active and inactive entities

The default search returns active records. Switch the status filter to include inactive, dissolved, and revoked entities. A dissolved name can sometimes be reused, but recently dissolved companies may still hold rights to the name for a period. If you find a close match in dissolved status, contact the Secretary of State at 701-328-4284 before you file.

4. Test variations and word order

Try keyword searches with different word orders and partial spellings. The portal supports “Starts With” and “Contains” searches. Run both. North Dakota law treats the addition of articles (“the,” “a,” “an”), conjunctions, punctuation, and pluralization as not creating distinguishability, so don’t assume those changes save you.

5. Check the trade name database

Trade names (DBAs) are searchable in the same FirstStop system. Even though a trade name doesn’t carry the same legal weight as an LLC name, an existing trade name registration can still create confusion and, in some cases, block your filing. Search the trade name registry for your proposed name before committing.

6. Confirm the domain and trademark

Once a name clears the state database, check whether the matching .com domain is available and run a quick search at USPTO’s TESS. State approval doesn’t shield you from federal trademark infringement claims. A name that’s free in North Dakota’s records can still belong to someone else nationally.

North Dakota LLC Naming Rules

Required designator

Your LLC name must end with one of these: “Limited Liability Company,” “Limited Company,” “LLC,” “L.L.C.,” “LC,” or “L.C.” North Dakota also allows “Ltd.” as an abbreviation for “Limited” and “Co.” for “Company.” Pick one and use it consistently across your Articles of Organization, EIN application, bank account, and contracts.

Distinguishable on the records

Your name has to be distinguishable from every active North Dakota business name, every registered foreign entity, every reserved name, and every registered trade name. Distinguishability is more than a one-letter difference. Adding “LLC” to a name that already exists as “Smith Construction Inc.” won’t work. Adding “North Dakota” or “ND” to a generic existing name usually won’t either.

Prohibited words

You can’t use words that suggest your LLC is a government agency. “FBI,” “Treasury,” “State Department,” and similar terms are off limits. You also can’t imply a corporate structure you don’t have, so no “Corp.,” “Corporation,” “Incorporated,” or “Inc.” in an LLC name.

Restricted words requiring approval

Certain words trigger extra paperwork or licensing. “Bank,” “trust,” “insurance,” “engineer,” “engineering,” and similar regulated terms require approval from the relevant state regulator before the Secretary of State will accept your filing. Professional terms like “doctor,” “attorney,” and “CPA” generally require that the LLC be formed as a Professional Limited Liability Company (PLLC) with licensed members.

What If Your North Dakota LLC Name Is Already Taken?

Try meaningful variations

Add a descriptive word that clarifies what you do: “Red River Consulting” becomes “Red River Tax Consulting.” Add a geographic specifier that’s actually distinguishing: “Bismarck Auto Repair” instead of “Auto Repair.” Avoid changes the state doesn’t recognize as distinguishing, which includes pluralization, articles, punctuation, and abbreviation swaps.

Reserve the name while you prepare to file

If you’ve found a name you want but you’re not ready to file Articles of Organization, you can reserve it for $20. The reservation holds the name for 12 months. File Form SFN 13015 (Reserve Name Application) through the FirstStop portal. This is useful when you’re still drafting your operating agreement, lining up a registered agent, or waiting on funding.

Register a trade name (DBA)

Your LLC’s legal name and the name you market under don’t have to match. You can form “RRV Holdings LLC” and register “Red River Coffee Roasters” as a trade name for $25. Trade names in North Dakota are valid for five years and renewable. This works well when your legal entity name is taken but you want a different brand name for customers.

Trademark considerations

State name approval is not a trademark. If another business holds a federal trademark on your proposed name in your industry, they can force you to stop using it even after North Dakota approves your filing. Run a USPTO search before you commit. For names you plan to scale nationally, consider filing your own federal trademark application.

After You Confirm Your North Dakota LLC Name

Once your name clears, the next step is filing Articles of Organization with the Secretary of State and appointing a registered agent. The state filing fee is $135. You’ll also need an EIN from the IRS (free) and an operating agreement (not filed with the state, but required in practice for banking and disputes).

Frequently Asked Questions

How do I know if a North Dakota LLC name is actually available?

Search FirstStop with the distinctive portion of the name (no designator), check both active and inactive statuses, and search the trade name registry. If you get zero matches and zero close variations, the name is likely available. The final word comes when the Secretary of State accepts your Articles of Organization.

How long does a North Dakota name reservation last?

12 months from the date the Secretary of State approves your reservation. The fee is $20. You can renew the reservation for another 12 months by filing again before the original reservation expires.

Can my LLC’s legal name be different from my business name?

Yes. Your LLC has one legal name (filed in your Articles of Organization) and can operate under one or more trade names. Register each trade name separately with the Secretary of State for $25. You sign contracts under the legal name and market under the trade name.

Does the .com domain need to match my LLC name?

No, but matching helps with branding and customer trust. Many founders pick a slightly different LLC legal name (often a holding-style name) and use a trade name and matching domain for the customer-facing brand. There’s no legal requirement that the domain match the registered LLC name.

What makes two North Dakota names “distinguishable”?

Real differences in the distinctive part of the name. “Red River Logistics” and “Red River Trucking” are distinguishable. “Red River Logistics” and “Red Rivers Logistics” probably aren’t. Punctuation differences, articles (“the,” “a”), and the LLC designator itself don’t count toward distinguishability.

Can I use a name that an out-of-state company uses?

Only if that company isn’t registered in North Dakota. If they’re registered as a foreign entity in the state, their name is protected here too. If they only operate in another state and have no North Dakota registration, you can generally use the name in North Dakota, though you should still check for federal trademark conflicts.
