How to Choose an LLC Name and Register a DBA the Right Way

Your LLC name appears on every document: state filings, the EIN, the bank, contracts. Changing it later means redoing work in all four places, so choose carefully from the start.

General naming rules

• The name must end with "LLC", "L.L.C." or "Limited Liability Company".
• It must not be identical or too similar to a name already registered in the same state (each state has its own "distinguishable" standard).
• It must not suggest a bank, insurer or government agency without the proper license.
• Words like "Bank", "Trust", "University" or "Attorney" are typically restricted or need extra approval.
• Each state sets the characters allowed; avoid special characters and accented letters.

Checking availability

1. Search for free on the Secretary of State business portal of the exact state where you plan to form.
2. Try spelling variants too (with or without periods, one word or two).
3. Search Google, social media and the USPTO trademark database to avoid brand conflicts — being allowed by the state does not give you trademark rights.
4. Check whether the domain name and social handles are still free.
5. Many states let you reserve a name for a short period for a small fee.

When do you need a DBA (assumed name)?

A DBA ("doing business as", also called an assumed name or trade name) is a name you trade under that differs from the LLC's legal name. For example the LLC is "Nguyen Holdings LLC" but the online shop is branded "Lotus Store". Many states require you to register the DBA with the state or county before using it in business. Rules and fees differ by state.

Common mistakes

• Picking a name too close to an existing one, so the state rejects it and you lose time refiling.
• Writing the LLC name on the EIN, bank and contracts in a way that doesn't match the state record exactly.
• Forgetting to register a DBA when using a brand name different from the legal name.
• Using someone else's trademark and facing a complaint after you have already invested in the brand.
