STEP 1: Name your Maine LLC

Choosing a company name is the first and most important step of forming an LLC in Maine. Be sure to choose a name that complies with Maine naming requirements and is easily searchable by potential clients.

1. Follow the naming guidelines:

• Your name must include the phrase “limited liability company” or one of its abbreviations (LLC or L.L.C.).
• Your name cannot include words that could confuse your LLC with a government agency (FBI, Treasury, State Department, etc.).
• Restricted words (e.g. Bank, Attorney, University) may require additional paperwork and a licensed individual, such as a doctor or lawyer, to be part of your LLC.
• Your name must be distinguishable from any other Maine, limited liability company, corporation, limited liability partnership or limited partnership.

For a complete list of naming rules in Maine, check out Maine's Naming Guidelines.

2. Is the name available in Maine? Make sure the name you want isn't already taken by doing a Business Entity Search on the Maine Secretary of State website.

3. Is the URL available? We recommend that you check to see if your business name is available as a web domain. Even if you don't plan to make a business website today, you may want to buy the URL in order to prevent others from acquiring it.
