  1. Entity Name
  2. Registered Agent Name and Registered Office Address

Entity Name

Having a creative and smart business name is important but not as important as having a legally correct name.

When you choose a name for your business, you have to make sure the name:

  • Meets Delaware naming guidelines. 
  • Is not already in use by another business in Delaware

Follow the Delaware 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.).
  • Your name may contain the following words: Company, Association, Club, Foundation, Fund, Institute, Society, Union, Syndicate, Limited, Public Benefit, or Trust.
  • Your name cannot contain the word "bank" or any variation unless the company is authorized as a bank by the state. However, the word "bank," or any variation, can be used if the context clearly doesn’t refer to a banking business or mislead the public about the nature of the business. An example of acceptable use would be Bank Shot Basketball LLC.
  • Your name must be distinguishable from any existing business in the state.

Check Name Availability:

Is your name available in Delaware? Make sure the name you want isn't already taken by doing a name search on the Delaware Division of Corporations website.

Register Your Domain Name:

We recommend checking 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.

Registered Agent and Registered Office

A registered agent accepts and sends legal documents on your LLC's behalf. When you register your Delaware LLC, you are required to list your registered agent and your registered office.

Your registered agent can be anyone 18 years or older that lives in Delaware. Your registered agent must always be available at the registered office during regular business hours. Your registered office address cannot be a P.O. box.

To learn more about choosing a Delaware registered agent, read our How to Choose a Delaware Registered Agent guide.

Steps After Your Delaware LLC Is Officially Formed

Once you’ve filed your Certificate of Formation, you should take the following steps:

Create an Operating Agreement

A Delaware LLC Operating Agreement is a legal document that outlines the ownership structure and member roles of your LLC.

In Delaware, you aren't required to have an Operating Agreement to officially form an LLC, but it's still a good idea to have one. You can start your operating agreement before, during, or after you file your Certificate of Formation.

Your operating agreement will be kept in your LLC's private business records; you do not file it with the state.

Use our free Operating Agreement Tool to draft a customized operating agreement for your LLC.

Get an EIN

An Employer Identification Number (EIN) is like a social security number for your LLC. You will need an EIN if you want to hire employees or open business bank accounts.

You can get your EIN for free through the IRS website, via fax, or by mail. If you would like to learn more about EINs and how they can benefit your LLC, read our What is an EIN article.

Open a Business Bank Account

Using dedicated business banking and credit accounts is essential to protect your business' corporate veil. When your personal and business accounts are mixed, your personal assets (your home, car, and other valuables) are at risk in the event your LLC is sued.

Get Licenses and Permits

When you are registering an LLC, you need to determine if your business needs any licenses or permits in order to remain compliant. On the federal level, there are a handful of business activities that require licenses and/or permits.

Find out how to obtain necessary licenses and permits for your business or have a professional service do it for you:

  • Federal: Use the U.S. Small Business Administration (SBA) guide to federal business licenses and permits.
  • State: Apply for or learn more about licenses, permits, and registration with Delaware's One Stop website.
  • Local: Contact your local county clerk and ask about local licenses and permits.
