You have a name for your company. It feels right.
But before you file anything, pay anyone, or tell the world about it — you need to answer one question:
Is this company name already taken?
This isn't just about avoiding awkward conflicts. Using a name that's already registered or trademarked can get your business forcibly shut down, sued, or forced into an expensive rebrand.
This guide walks you through exactly how to check if a company name is taken — across state registries, trademark databases, domains, and social platforms — before you register anything.
Quick Answer
To check if a company name is taken:
- Search your state's business registry
- Check the USPTO trademark database
- Check domain availability
- Check social media handles
- Check broader platform availability

Why This Check Matters More Than Most Founders Realise
Most founders think registering a company name with their state gives them full rights to that name. It doesn't.
Here's what actually happens when you skip this check:
- You register an LLC with a trademarked name → they can still sue you
- You build a brand around a name taken on every social platform → users can't find you
- You launch publicly with a name a competing company already uses → SEO becomes a nightmare
- You raise funding and a name conflict surfaces in due diligence → deal falls apart
The 20 minutes you spend checking now saves months of pain later.
Step 1: Check Your State Business Registry
Every US state has a free public business name search tool.
Search "[your state] business name search" or "[your state] Secretary of State business search."
Examples:
- California → California Secretary of State Business Search
- Delaware → Delaware Division of Corporations
- Texas → Texas Secretary of State SOSDirect
- New York → New York Division of Corporations Entity Search
- Florida → Florida Division of Corporations Sunbiz
What to look for:
- Exact matches → cannot use the same name in the same state
- Similar names → may still cause legal risk
- Active vs inactive status → inactive registrations may still block you
Important: State registration only protects you within that state. It does not give you national rights.
Step 2: Check the USPTO Trademark Database
This is the most critical check — and the one most founders skip.
Go to: https://tmsearch.uspto.gov
Search your exact company name using the Wordmark search.
What the results mean:
- Live / Registered → Active trademark. High risk. Do not use without legal advice.
- Live / Pending → Application in progress. Still risky.
- Dead / Abandoned → No longer active. Lower risk but worth understanding why.
Also search variations, shortened forms, and phonetically similar names — trademark law covers names that are confusingly similar, not just identical.
For global coverage also check WIPO: https://branddb.wipo.int

Step 3: Check Domain Availability
Check in this order:
- .com — highest priority
- .io — widely accepted for startups
- .ai — strong for AI products
- .co / .app / .dev — acceptable alternatives
How to evaluate a taken domain:
- Active business in your industry → high risk, find another name
- Parked with no content → lower risk, may be purchasable
- Different industry entirely → manageable but not ideal
Step 4: Check Social Media Handles
Check at minimum:
- YouTube
- X (Twitter)
What to look for:
- Active account with followers → real conflict, avoid this name
- Dormant or empty account → lower risk, may be claimable
- Different industry → still creates confusion
Step 5: Check Broader Platform Availability
For tech/SaaS products:
- GitHub — active org means real conflict
- npm — if building developer tools
- Product Hunt — existing product affects launch positioning
For all businesses:
- Reddit — active subreddit means strong existing brand association

What to Do If the Name Is Taken
State Registry Conflict
- Same name, same state → you cannot register it
- Same name, different state → legally allowed but creates brand confusion
- Similar name, same state → may still be rejected
Trademark Conflict
- Live / Registered in your industry → avoid or consult attorney
- Live / Registered in unrelated industry → medium risk, get legal advice
- Dead / Abandoned → lower risk, understand the context first
Domain Conflict
- Active competitor, same industry → find a new name
- Parked domain → consider purchasing
- Different industry → assess confusion risk
Social Handle Conflict
- Active account with real following → reconsider the name
- Dormant account → platforms sometimes allow claiming inactive handles
The Real Cost of Getting This Wrong
- Cease and desist letters requiring immediate rebranding
- Legal fees ranging from $5,000 to $50,000+
- Lost momentum, users, and investors during a rebrand
- SEO damage from competing with an established brand

FAQs
How do I check if a company name is taken for free?
Start with your state's Secretary of State business search, then check the USPTO trademark database, then check domain and social availability using BrandNameCheckr — all free, no signup.
Does registering an LLC protect my company name nationally?
No. LLC registration only protects your name within your state. Federal trademark registration gives you national protection.
Can two companies have the same name in different states?
Legally yes — if neither holds a federal trademark. But it creates brand confusion and SEO problems.
How long does a full company name check take?
20–30 minutes manually. Using BrandNameCheckr, the platform check takes under a minute.
What's the difference between a business name and a trademark?
A business name is an administrative record. A trademark is a legal right giving you exclusive use of a name in a specific industry.

Checking if a company name is taken is not a formality. It is the single most important thing you do before committing to a name.
