By Jake Lawson, LLC Formation Strategist
Montana might be known for wide open spaces, but when it comes to LLC names, the Secretary of State doesn’t give you much wiggle room. I’ve helped entrepreneurs navigate Montana’s business entity search system for over 15 years, and let me tell you—getting your name search wrong here can be particularly frustrating.
Why? Because Montana has some of the most detailed distinguishability rules I’ve encountered. They spell out exactly what makes business names too similar, which is both helpful and intimidating. The good news? Once you understand their system, it’s actually quite predictable.
Let me walk you through everything you need to know to get your Montana LLC name approved on the first try.
Why Montana Takes LLC Name Searches Seriously
Montana operates under Section 35-8-103 of the Montana LLC Act, which requires business names to be “distinguishable upon the records.” But here’s what makes Montana different: they’ve codified exactly what “distinguishable” means in Rule 44.5.131.
Translation: Montana doesn’t leave name approval up to individual judgment calls. They have specific, detailed rules about what constitutes a name conflict.
The cost of getting it wrong: A rejected filing, lost time, and the hassle of starting over. Unlike some states that give you grace periods, Montana makes you pay the filing fee again if your name gets rejected.
Pro tip from my 1,200+ client experiences: Montana’s detailed rules are actually your friend. Once you understand them, you can predict with high accuracy whether your name will be approved.

My Montana Name Search Strategy: The Advanced Approach
Most people do a quick search and call it good. That’s amateur hour in Montana. Here’s my proven methodology:
Step 1: Set Up Your Search Correctly
- Click the “Advanced Search” tab
- Enter your core business name (without “LLC”)
- Critical setting: Change search type to “Contains” (not “Starts With”)
- Leave other settings on default
- Click Search
Why “Contains” beats “Starts With”: If you search “Hamburger Guy” using “Starts With,” you’ll miss “The Hamburger Guy Inc.” But that existing business would absolutely block your “Hamburger Guy LLC” filing.
Step 2: The Comprehensive Search Sequence
For “Riverwalk Studios LLC,” I search:
- Primary search: “Riverwalk Studios”
- Variation search: “Riverwalk Studio” (singular)
- Core word search: “Riverwalk”
- Secondary word search: “Studios”
- Partial searches: “River,” “Walk,” “Studio”
This catches everything that could potentially conflict with your desired name.
Step 3: The Clean Search Technique
What to exclude from searches:
- LLC, L.L.C., Limited Liability Company
- Punctuation: commas, periods, apostrophes
- Articles and filler words: the, a, an, and, or
Case sensitivity: Montana treats all capitalization the same, so search however is easiest for you.
Understanding Montana’s Search Results
Montana’s search results are straightforward, but interpreting them correctly requires understanding their specific distinguishability rules.
Green Light Scenarios ✅
No results: Your name is likely available, but run broader searches to be certain.
Clearly different businesses: If you want “Riverwalk Studios LLC” and only see “Riverwalk Ranch” and unrelated businesses, you’re probably good.
Red Light Scenarios ❌
Exact matches: Any business with your exact name (regardless of entity type) blocks your filing.
Montana Rule 44.5.131 violations: Names that fall under their specific “not distinguishable” categories.
Yellow Light Scenarios ⚠️
Borderline similar names: When you’re not sure, call Montana directly at 406-444-3665 (Monday-Friday, 8am-5pm Central).
Montana’s Comprehensive Distinguishability Rules
This is where Montana gets detailed. Rule 44.5.131 spells out exactly what doesn’t create distinguishability:
1. Designators Don’t Matter
“Mourning Cloak Clothier LLC” conflicts with:
- “Mourning Cloak Clothier Inc.”
- “Mourning Cloak Clothier Corp.”
The entity type ending is irrelevant for uniqueness.
2. Punctuation and Symbols Are Ignored
“Wheatgrass Soapstore LLC” conflicts with:
- “Wheat-grass-Soap-store Inc.”
- “Wheatgrass/Soapstore Limited Liability Co.”
- “Wheat+Grass Soapstore LC”
Montana ignores all punctuation when determining similarity.
3. Capitalization Doesn’t Create Uniqueness
“CutThroat Trout LLC” conflicts with:
- “cutthroat trout Inc.”
- “Cutthroat TROUT LP”
- “CuT ThRoAt TrOuT LLC”
Capitalize however you want—it won’t make your name unique.
4. Filler Words Are Disregarded
Montana specifically lists these as non-distinguishing:
- Articles: a, an, the
- Prepositions: by, of, for
- Conjunctions: and, or, &, but
- Contractions: don’t, I’m, etc.
“Bluebunch Farms LLC” conflicts with “The Bluebunch and Farms Inc.”
5. Internet Domain Suffixes Don’t Help
“PonderosaPines.com LLC” conflicts with:
- “Ponderosa Pines Inc.”
- “PonderosaPines.org LLC”
6. Plural vs. Singular Doesn’t Work
“Molly’s Mittens LLC” conflicts with:
- “Molly’s Mitten Inc.”
- “Mollys Mittens Corp.”
7. Numbers vs. Spelled-Out Numbers
“25 Stars LLC” conflicts with:
- “Twenty-Five Stars Inc.”
- “XXV Stars Corp.” (Roman numerals)
8. Word Variations Usually Don’t Work
“Meadowlark Creations LLC” might conflict with:
- “Meadowlark Creatives LLC”
- “Meadowlark Creates Inc.”
Note: This depends on the examiner’s interpretation of whether the variations have different meanings.
Montana’s Helpful Exceptions
Montana does provide some ways to create distinguishability:
Exception 1: Unique Spellings
“Boyz Basketz LLC” might be distinguishable from “Boys Baskets Inc.”
Caveat: The examiner still has discretion if they think names are confusingly similar.
Exception 2: Homophones (Different Meanings)
“Sole Studios LLC” (shoe design) is distinguishable from “Soul Studios LLC” (music recording) because they have different meanings.
Exception 3: Word Order Changes
“Gold Silver Sky LLC” becomes distinguishable as:
- “Sky Gold Silver LLC”
- “Silver Gold Sky LLC”
Exception 4: Abbreviations vs. Full Words
“NY Pizza Bros LLC” is distinguishable from “New York Pizza Brothers Inc.”
Montana LLC Naming Requirements
Required Designators
Your Montana LLC name must end with one of these options:
- LLC
- L.L.C.
- Limited Liability Co.
- Limited Liability Company
- LC
- L.C.
- Limited Company
- Limited Co.
- Ltd. Liability Co.
- Ltd. Liability Company
Reality check: Despite all these options, 99% of my clients choose “LLC.” It’s clean and universally recognized.
Forbidden Designators
Don’t try to sound like other entity types:
- Inc., Incorporated
- Corp., Corporation
- Ltd. (when used alone)
- LP, LLP
- Cooperative
Restricted Words
Montana specifically prohibits certain words that could mislead the public:
Government-related:
- Federal, Government, FBI
- United States, United States of America
- City, Borough, Township, County
Professional designations:
- Words reserved for licensed professionals (attorneys, architects, engineers, etc.)
Financial services:
- Bank, insurance company terms (context-dependent)
Strategic Approaches for Name Conflicts
When your perfect name isn’t available, here are my battle-tested strategies:
Strategy 1: Creative Spelling
Instead of “Boys Baskets LLC,” try:
- “Boyz Baskets LLC”
- “Boys Basketz LLC”
Strategy 2: Word Reordering
“Mountain River Lodge LLC” becomes:
- “River Mountain Lodge LLC”
- “Lodge Mountain River LLC”
Strategy 3: Abbreviation Swapping
“Montana Technical Services LLC” becomes:
- “MT Technical Services LLC”
- “Montana Tech Services LLC”
Strategy 4: Synonym Substitution
“Outdoor Adventure LLC” becomes:
- “Wilderness Adventure LLC”
- “Outdoor Expedition LLC”

DBA Strategy for Montana LLCs
Sometimes your perfect marketing name isn’t available as your legal LLC name. Montana’s Assumed Business Name process can solve this.
The process:
- File online at Montana’s business portal
- Pay $20 filing fee
- The assumed name must also pass distinguishability requirements
- No limit on the number of assumed names
Common scenarios:
- Legal name: “Skytree Cruise Lines LLC”
- Marketing name: “Sky Cruises” (requires DBA)
- Operating without “LLC”: “Skytree Cruise Lines” (requires DBA)
Domain Name Coordination: Don’t Skip This Step
Before falling in love with any business name, check domain availability. Nothing’s worse than securing “Perfect Business Name LLC” but being stuck with “PerfectBusinessNameLLC.net” for your website.
Pro tip:
Check domain availability before you even start the Montana name search process.
Skip the Name Reservation Trap
Here’s some free advice: Montana name reservations are unnecessary and a waste of money.
Just file your Articles of Organization directly. If the name gets rejected, you’ll know quickly and can adjust accordingly.
When Your Montana Filing Gets Rejected
Don’t panic—I’ve helped dozens of entrepreneurs through this scenario.
What happens:
- Montana notifies you of the rejection
- They explain the specific reason
- You file again with a compliant name
- You pay the filing fee again (no grace period like some states)
My recovery strategy:
- Review the rejection reason against Rule 44.5.131
- Apply the specific distinguishability rules
- Run your new name through the same thorough search process
- File promptly to minimize delays
