How to Name an LLC

A state checks five things in an LLC name, and none of them is whether the name is good. This guide covers the designator every state requires, the words most states restrict, what "distinguishable" means on a state register, when a DBA is the better move, and how the .com fits into a decision the state does not care about.

None of this is legal advice. It is the checklist that keeps a filing from bouncing, written so you can run it before you pay anyone.

The designator is not optional

Every state requires the legal name of a limited liability company to say what it is. The accepted forms are close to the same everywhere: LLC, L.L.C. or the words Limited Liability Company; some states also take Ltd. Liability Co. or Limited Company. The designator is part of the legal name, so it goes on the filing, the bank account and the contracts. It does not have to go on the sign, the website or the logo, which is where most people first meet the name.

Pick the form once and keep it. "Acme LLC" and "Acme, L.L.C." are the same company to you and two different strings to a bank's compliance software. The LLC name generator adds the designator you choose to every result so what you copy is the form you will file.

Words most states restrict

A state will refuse, or ask for approval before accepting, a name that implies a licensed profession or a regulated business the company is not. The usual list: Bank, Trust, Insurance, University, College, Federal, Attorney, Engineer, Architect, CPA, Doctor and anything suggesting a government body. Some states extend it to Savings, Mortgage, Olympic or Cooperative. The point is not that these words are forbidden; it is that each one has a regulator who gets to say yes, and the filing waits until they do.

The generator keeps these words out of its results. If a word you typed brings one in, the row says so. Your state's list is the one that counts, so read it before you file.

"Distinguishable" is a narrower test than "different"

A state accepts an LLC name only if it is distinguishable on its records from every entity already registered there, active or recently dissolved. Distinguishable is a clerk's test, not a marketing one: it ignores the designator, usually ignores punctuation, spacing, capitalisation and the words the, a and and, and in most states ignores singular and plural. "Acme Ledger LLC" is not distinguishable from "Acme Ledgers, L.L.C." even though a customer would never confuse the two companies.

So search the exact name and its near spellings on your state's register before you fall in love with it. Pick your state in the generator and every result links to that search. If the name is taken, changing a word beats adding a word: "Acme Ledger Group" may pass the clerk and still look like a copy to everyone else.

When a DBA is the better move

The legal name and the trading name do not have to match. A DBA ("doing business as", called a fictitious or assumed name in some states) lets "Northwind Holdings LLC" trade as "Northwind Coffee" without a second company. That is the right tool when the legal name is a family name, when one company will run two brands, or when the brand you want is fine as a trading name but would fail the clerk's test as a legal one.

A DBA does not protect the name; only a trademark does that. It also does not free you from the restricted-word rules, which apply to trading names in most states. Treat it as a label on the same company, not a second identity.

The .com is a separate question the state never asks

The state register, the trademark register and the domain registry are three different lists kept by three different bodies, and clearing one says nothing about the others. A free .com does not mean the LLC name is free in your state, and a state accepting the name does not mean the .com is free or that no one holds the trademark.

The practical order: search the state register first, because it is the one that bounces a filing; then check the .com, because it is the one you cannot negotiate with a clerk; then a trademark search, because it is the one that can take the name back later. The generator's Check .com reads the public registry once for the exact domain, without the designator, and says when it looked. Register the domain the day you decide, not the day you file.
