Checking whether a business name is taken requires searching multiple databases, not just one. A name can be claimed at the state level, federally trademarked, registered locally as a fictitious business name, or simply in use online without any formal registration. Missing any of these layers can lead to a forced rebrand or legal trouble after you’ve already printed business cards and built a website. Here’s how to run a thorough search.
Search Your State’s Business Registry
Every state maintains a database of registered business entities (corporations, LLCs, and limited partnerships) through its Secretary of State or equivalent office. Most of these databases are free and searchable online. Go to your state’s Secretary of State website, find the business name search tool, and type in the name you want to use.
The search will show you whether an identical or very similar name is already registered. States generally require that new business names be “distinguishable on the record” from existing ones, which means minor tweaks like adding “LLC” to the end or swapping “and” for “&” usually won’t make a taken name available. If your exact name or something closely resembling it shows up as an active entity, you’ll need to choose something different to register in that state.
Keep in mind that this search only covers formally registered entities in that one state. It won’t show you sole proprietorships operating under their owner’s legal name, businesses registered in other states, or names protected by federal trademark law. That’s why the state search is just your first step.
Check the Federal Trademark Database
Even if a name is available in your state’s registry, someone else may hold a federal trademark on it. Using a trademarked name can result in a cease-and-desist letter or a lawsuit, regardless of whether you registered your business first in your state.
The U.S. Patent and Trademark Office (USPTO) maintains a free search tool at uspto.gov. To use it effectively, search the “combined mark” field using the tag “CM:” followed by your name. If your name has multiple words, put them in quotes. For example, entering CM:"bright path consulting" searches for that exact phrase.
Don’t stop at an exact match. The legal standard for trademark conflicts is “likelihood of confusion,” which means trademarks that look alike, sound alike, have similar meanings, or create similar commercial impressions can all cause problems. Search for alternative spellings, phonetic variations, and individual strong words from your name. A business called “Brite Path” could conflict with “Bright Path” even though they’re spelled differently.
One important limitation: the USPTO database only contains federal trademark applications and registrations. It does not include businesses that have what are called “common law” trademark rights, meaning rights earned simply by using a name in commerce without ever filing a federal application. A company that’s been operating under a name for years in your region may have enforceable rights even though they never registered with the USPTO. That’s why a broader internet search matters too.
Look Up Local Fictitious Business Name Filings
Sole proprietors and partnerships that operate under a name different from the owner’s legal name typically must file a fictitious business name statement (also called a DBA, short for “doing business as”) with their county clerk or a similar local office. These filings won’t appear in your state’s main business entity database.
Many counties now offer online search portals where you can look up active fictitious business name filings by business name, city, or zip code. Check the county clerk or recorder’s website for the county where you plan to operate. Some counties only have records going back a few years online, so if you want older records, you may need to call or visit the office in person. A DBA filing doesn’t carry the same legal weight as a trademark, but discovering that someone nearby is already using your desired name under a DBA can save you from customer confusion and potential disputes.
Search the Web and Social Media
A business doesn’t need to be formally registered anywhere to have common law trademark rights. If someone is actively using a name in commerce, selling products or services under it, they may be able to enforce that name in their geographic area. The simplest way to uncover these unregistered users is a plain Google search. Type your proposed name in quotes, and look through the first several pages of results. Try variations with and without spaces, hyphens, or abbreviations.
Beyond Google, check whether the name is claimed as a domain. If someone already owns yourbusinessname.com (or .net, .co, or other common extensions), that’s a signal the name is in use, and it also means you’ll have trouble building your own web presence. Any domain registrar’s search tool will tell you instantly whether a domain is available.
For social media, tools like Namechk let you enter a name once and see its availability across dozens of platforms simultaneously, including Facebook, YouTube, TikTok, Instagram, and more. If the name shows as taken on multiple platforms, someone is likely already building a brand around it. Even if you could legally use the name, having mismatched or unavailable handles across social channels makes marketing harder. Ideally, you want a name that’s available as a domain and on the major social platforms you plan to use, so your branding stays consistent everywhere.
What To Do When a Name Is Partially Taken
Sometimes your search results will be mixed. The name might be available in your state’s registry but taken as a domain. Or the domain is open but a similar name holds a federal trademark. How you handle this depends on where the conflict is.
If the name is taken in your state’s business registry, you simply can’t register it there. You’ll need to modify the name or choose a new one. If the conflict is a federal trademark, tread carefully. Using a name that’s confusingly similar to a registered trademark, even in a different state, can expose you to legal action, especially if you operate online and your customers overlap geographically.
If the name is in use by a small local business with no trademark registration, the risk is lower but not zero. That business may still have common law rights in their area. If you’re in the same city or industry, a conflict is much more likely to become a problem than if you’re in a completely different market thousands of miles away.
If the domain is taken but nothing else conflicts, you have options: try a different domain extension, slightly adjust the name, or reach out to the current domain owner to see if they’re willing to sell. Just be aware that premium domains can cost hundreds or thousands of dollars.
Reserve Your Name Once It’s Clear
After confirming a name is available across all the databases that matter, move quickly. Names aren’t held for you while you think it over. Most states let you reserve a business name for a set period (often 60 to 120 days) for a small fee before you formally register your entity. This buys you time to finalize your formation paperwork without losing the name to someone else.
At the same time, register the domain and claim your social media handles. These are first-come, first-served, and there’s no reservation system. If you plan to build a brand around the name long-term, filing a federal trademark application with the USPTO gives you the strongest nationwide protection, though the process takes several months and involves fees starting at $250 per class of goods or services.
