Delaware Business Name Change

If you want to expand or evolve your Delaware business, a name change can help reflect its new mission. Changing a business name requires you to file paperwork with the Division of Corporations in the Department of State. Filing will officially change the name your business uses on any official documents, like annual reports, taxes, or employee paychecks. It’s an essential step to keeping your business compliant with the law.

To complete a business name change in Delaware, you’ll need to file a Certificate of Amendment for an LLC or Certificate of Amendment of Certificate of Incorporation for a corporation. This page will help you prepare to fill out and file your amendment. With our Amendment Filing Service, we can complete the paperwork for you, leaving you free to manage your business.

The rest of this page will guide you through the steps of how to change a business name in Delaware.

How to Get a New Business Name

Before you can change your business name in Delaware, you’ll need to prepare to complete a Certificate of Amendment. First, you’ll choose a name that complies with the state business requirements. Then, you’ll want to gather the information from your business formation documents. Finally, you’ll need to plan a time to file the amendment with the Division of Corporations.

1.) Choose a new business name

Your new name should reflect the new goals for your business, so you can make it whatever you want. However, before you can register your new business name, it must comply with the state’s naming requirements, including:

You have many choices when including an identifier in your name. However, ensuring your name is distinguishable requires searching and comparing all Delaware registered business names to yours. Delaware defines “distinguishable” loosely. A name is considered distinguishable if it uses the plural form of a word when another business uses the singular form or uses the same keywords in a different order.

Let our business experts help you complete the search with our Business Name Services. We’ll complete a name search with the Delaware Division of Corporations and even check for an available domain name. Once you’ve guaranteed that your name is unique, if you’re not ready to use your name immediately, you can consider reserving the name for 120 days.  

2.) Gather information for filing your amendment

A name change involves filing an amendment to your business formation documents. Thus, one necessary step is to gather the information you included in your Certificate of Formation or Certificate of Incorporation. To complete the Certificate of Amendment or Certificate of Amendment of Certificate of Incorporation, you’ll need:

If you’re filing a paper form, you’ll need a cover letter with your name, address, and telephone or fax number. The software will generate a cover letter for you if you file online. Finally, prepare to pay a filing fee, which will vary with the type and size of your business. You can find the updated fee amounts on the Delaware Division of Corporations’ website.

3.) File your Delaware amendment 

Once you have all the information you need to complete your amendment form, it’s time to file with the Division of Corporations. You may file on the website using the state’s electronic Document Upload Service or by mail. To pay your filing fee, you’ll need an American Express, Discover, MasterCard, or Visa card for online payments or a check if filing by mail.

While it takes time to complete the amendment process, we can save you time with our Amendment Filing Service. Our experts will help you complete your amendment wholly and accurately.

  1. What's the difference between a doing-business-as (DBA) name and business name? 

    When a business uses a name other than the one on its formation documents, it must file a doing-business-as (DBA) name with the county Prothonotary’s office. Filing a DBA allows the public to search for and identify the business and its owners. Even if you have a DBA name, any government documents you file, including taxes, need to use your official, registered name.

  2. Do I have to change my business name if I have a DBA name? 

    A DBA name is separate from your official registered name. If you want to change the name you use when filing documents with the government, follow the steps on this page. If you simply want to use a different name while conducting your business, you can file a DBA.

  3. How do I register my business name in Delaware? 

    First, you’ll need to verify that your business name is distinguishable from other businesses registered in Delaware. You’ll certify your name when you register with the Division of Corporations if you’re starting a new business. If you’re changing an existing business name, you can reserve the name for your exclusive use for 120 days while preparing your Certificate of Amendment using the steps outlined on this page.

  4. How many amendments can I make to my business?

    You can use the same form to make several amendments. If you later need to make more changes to your formation documents, you may file additional amendments.
