Every state maintains a business entity database through its Secretary of State office. Before you can register a business name, the state must confirm it is distinguishable from every existing entity on record. "Distinguishable" does not mean unique in everyday terms — most states apply a deceptive similarity test that screens out names too close to an active LLC, corporation, or limited partnership.
Certain words are restricted or reserved in nearly every jurisdiction. Using "Bank," "Trust," "Insurance," or "Credit Union" typically requires a license from the relevant state regulator. Words like "University" or "College" may need approval from the state education department. If your desired name includes a restricted word without the proper authorization, the filing will be rejected.
| Entity Type | Required Suffix | Acceptable Variations |
|---|---|---|
| LLC | LLC, L.L.C. | Limited Liability Company, Limited Liability Co. |
| Corporation | Inc., Corp. | Incorporated, Corporation, Company, Co., Ltd. |
| Limited Partnership | LP, L.P. | Limited Partnership |
| Sole Proprietorship | None required | May operate under owner's name or a DBA |
Most states let you reserve a name before filing formation documents. Reservation periods range from 60 days (California) to 120 days (New York, Texas), and fees run from $10 to $40. Reservation buys time to finalize your operating agreement, line up an EIN, and secure a domain — without risking someone else registering the same name.
Your legal name is the name on your formation documents filed with the state. A DBA (Doing Business As) — also called a fictitious business name or trade name — lets you operate under a different public-facing name without forming a new entity. For example, "Smith Holdings LLC" could file a DBA for "Greenfield Coffee" and accept payments, open bank accounts, and sign contracts under that name.
DBA registration is handled at the county level in most states (California, New York, Texas) or at the state level in others (Florida, Colorado). County-level filings usually require publishing a notice in a local newspaper for a set number of weeks. The cost ranges from $10 to $100 depending on the county and publication fees.
A state registration or DBA does not give you trademark protection. To confirm your name does not infringe on an existing mark, search the USPTO TESS database (Trademark Electronic Search System) at tmsearch.uspto.gov. Run both an exact-match search and a "free-form" search using phonetic equivalents. A federal trademark registration (filed through the USPTO) costs $250–$350 per class and grants nationwide protection against later filers in the same goods/services category.
If you plan to operate across state lines or build a consumer brand, filing a federal trademark early avoids costly rebranding down the road. State-level trademark filings exist but offer protection only within that single state.
Securing a domain name should happen the same day you settle on a business name — ideally before you file formation paperwork. A .com domain remains the most trusted extension for U.S. businesses, but .co, .io, and industry-specific TLDs (.law, .tax, .agency) can work if the .com is taken. Expect to pay $10–$15/year for a standard registration or significantly more for a premium aftermarket domain.
When evaluating name candidates for branding, prioritize these factors:
Run your top choices through the Google Ads Keyword Planner to check monthly search volume for that term. If thousands of people already search for a phrase matching your business name, you gain a built-in SEO advantage. Conversely, if the term is dominated by a large competitor, ranking will be harder regardless of your content strategy.
Finally, consider how the name looks as a logo and as a URL. Names with double letters (e.g., "pressstart") or ambiguous word boundaries (e.g., "kidsexchange") can cause readability issues. Test your shortlist with real people — not just founders — before making it official.
