Picking a business name is the fun part. Finding out whether you’re actually allowed to use it is the part almost everyone skips, and it’s how a founder ends up printing new business cards eight months in. If you want to check business name availability the right way, a single Google search or a five-second domain lookup won’t cut it. The process usually means clearing three separate systems, and they don’t talk to each other.
Most people start with the fun database: a domain registrar, or Instagram’s handle search. That instinct is backward for a business name. The system that can actually stop you from operating under a name is your state’s business registry. It has nothing to do with whether yourbrand.com is free. Guides published by LLCBuddy and similar formation resources exist because this order of operations trips up so many new owners.
Start with your secretary of state, not a search engine
Every state runs a searchable database of registered business entities, usually through the Secretary of State’s office. It’s the only opinion that carries legal weight before you file. Type your proposed name in. The system checks it against every corporation and LLC on the books in that state, and limited partnerships too.
What it checks for is narrower than most people assume, and sometimes counterintuitive. States generally don’t ban similar names outright. They ban names that aren’t “distinguishable in the records” from an existing one. California adopted that exact standard in 2021 under SB 522, replacing an older, stricter rule that blocked names merely because they were deceptively similar, and it remains the current standard as of 2026. California’s own regulations show how narrow “distinguishable” really is.
Changing only a business identifier doesn’t count, so an LLC called Good Time Rest Home, LLC is not distinguishable from one already on file as Goodtime Rest Home LLC, even though the two read differently on the page. Move a space in the right spot, though, and the outcome flips: Got Ham LP is treated as distinguishable from Gotham, LP, because closing the gap creates an entirely different word. It’s not intuitive, and it’s not consistent state to state.
According to LLCBuddy, which tracks LLC formation costs across all 50 states, the price of confirming and locking in a name swings wildly depending on where you file. As of 2026, California charges $10 to reserve a name for 60 days through the Secretary of State’s bizfile portal, plus an extra $10 if you insist on dropping the paperwork off in person.
Delaware, by contrast, currently charges $75 for a 120-day hold through its Division of Corporations. Neither fee is large in the context of starting a company. But the gap tells you something: name reservation is a state-by-state product, priced and timed differently depending on where you file, not a standardized formality. Those numbers are worth double-checking against the state site before you file, since fees do change.
This step is easy to treat as optional, but skipping it carries real risk. A preliminary database search that comes back clean is not a reservation. It doesn’t hold the name. Someone else can file the same name an hour later. If you’re not ready to submit your formation documents today, that gap is exactly what a reservation is for.
The trademark layer people forget exists
Clearing your state’s registry tells you that you can legally form an entity under that name in that state. It tells you nothing about whether you can use it as a brand nationally, or whether someone in another state already owns it as a trademark and can eventually force you to stop.
The U.S. Patent and Trademark Office maintains its own searchable database, separate from any state system, and it operates on entirely different logic. Trademark protection is about the likelihood of confusion between goods and services, not exact text matches. The USPTO’s own guidance points to Dove as the textbook case.
Dove soap and Dove ice cream bars are both federally registered, to two unrelated owners, because no reasonable customer would confuse a bar of soap with a carton of ice cream. That same flexibility works against you if your state-approved name turns out to overlap with a trademark in your own industry. State approval and trademark clearance are two different green lights. Having one says nothing about the other.
This step gets skipped constantly, probably because it feels redundant after a state search that already came back clean. It isn’t a redundant check. It’s often the reason a rebrand happens down the line.
Check the domain and the handles, but do it last
Domain and social handle availability matter enormously for practical, day-to-day branding. But registering one doesn’t by itself grant or protect any legal right to use a business name, and treating the domain check as the first filter gets the priority order backward. A name can be completely open on every registrar and still be unusable, because another company already has state or federal rights to it. Many founders find it safer to run the legal checks first. Only spend energy on the domain hunt once the name has actually survived them.
If the exact match is taken, that’s rarely fatal. Founders route around this constantly: a slightly modified handle, or a different top-level domain. The legal entity name stays as filed either way. The marketing name can differ under a separate “doing business as” filing.
Reservation buys time. It doesn’t buy certainty.
Steve Goldstein founded the site, one of several formation-focused resources that walk through this process state by state. The reservation decision doesn’t need a citation to make sense. It’s cheap insurance against a very specific problem, not a requirement for anyone ready to file today. If your paperwork is prepared and you’re filing this week, reserving first just adds a step and a fee. Reservation earns its cost when there’s a real gap: you’re still raising money, or waiting on a partner’s signature, and you’re hoping the name sits still while that gap closes.
One detail is easy to miss until it costs you money: a reservation window is a hard deadline, not a soft one. Miss California’s 60 days or Delaware’s 120 (both current as of 2026), and the name goes back into circulation. California explicitly bars renewing the exact same reservation for consecutive periods. You can request the name again once it lapses, but there’s no guarantee it’s still open when you do. The reservation period is the actual amount of time available, not a flexible suggestion.
A clean name search still leaves DBAs unaccounted for
One more wrinkle catches people who did everything else correctly: your entity name and the name you actually operate under in public can be two different things, filed in two different places. A “doing business as” registration is typically handled at the county level, separate from the state entity registry entirely.
That means a name can be completely free as an LLC name and, at the same time, in use as someone else’s DBA a few counties over, or the reverse. If your marketing name won’t match your legal entity name exactly, that DBA filing is one more thing worth checking separately. Skipping it is how two unrelated businesses end up operating under the same public-facing name in the same market, discovering each other by accident.
What this actually costs you in time
Budget more than an afternoon for the name search alone.
A state entity search takes minutes. A trademark search, done properly rather than as a five-second skim, takes longer if your industry is crowded. A reservation filing can take days to process, depending on the state and whether you pay for expedited handling. None of this is legal advice, and requirements vary enough by state and entity type that a generic checklist can’t substitute for reading your own state’s current rules directly on the Secretary of State’s site before you file anything. LLCBuddy is not a law firm or a licensed filing service. Neither is any blog post, including this one.
If you’re also weighing which formation service to hire once the name is confirmed, a comparison of full-service LLC providers covers that question separately. Comparing providers before you know the name survives a search is effort spent on the wrong problem.
The order matters more than the name
A name you love and can’t use is just an idea. The name that survives is the one no database, examiner, clerk, or another company’s trademark got around to rejecting. The one you loved first doesn’t get a vote.
