General Rules for Corporation Names

These rules generally apply to all corporations, wherever they're formed.

Your Corporation Name Must Be Unique

The name you decide on cannot be in use by any other business in the state. This is why it's so important to perform an Iowa State corporation search before you begin your incorporation paperwork.

Your Name Must Not Be Confusable with Another Business Name

It’s not enough for your business name to be unique. It also cannot be similar to the name of another entity in the state. In addition, you cannot use any of the following features in an attempt to differentiate your corporation name from that of another business:

  • Suffixes, such as Corporation, Company, Incorporated, Incorporation, Limited, Corp., Co., Inc., etc.
  • Definite articles, such as “A,” “An” or “The”
  • The conjunction "And" or “&"
  • Numbers in place of numerals (or vice versa), e.g., "One World" is the same as "1 World"
  • The singular, plural or possessive forms of words
  • Abbreviations, punctuation, symbols, fonts, typefaces, etc.
Your Corporation Name Must Contain Certain Words

All corporations must use one of the following in their names, usually at the end of the name: “Incorporated,” “Corporation,” “Limited” or their abbreviations.

Your Corporation Name May Be Subject to Other General Restrictions

Most states will not allow you to incorporate with names that:

  • Are similar to the name of a federal or state agency or organization (e.g., FBI, FDA, Iowa Department of Revenue, Iowa Rangers, Treasury, etc.)
  • Suggest affiliation with a federal or state agency or organization
  • Use the term “Olympic” or any terms that are trademarks of the International Olympic Committee
  • Imply a purpose that would be illegal for your business to carry out

Specific Rules for Iowa Business Names

In addition to the general rules listed above, you'll need to follow some Iowa corporation laws that apply to naming your business.

For example, per the Iowa Code Title 12, Chapter 490, § 490.401, the name of a corporation or foreign corporation must "contain the word “corporation”, “incorporated”, “company”, or “limited”, or the abbreviation “corp.”, “inc.”, “co.”, or “ltd.”, or words or abbreviations of like import in another language."

In addition, Title 12, Chapter 490, § 490.401 states that a corporation name "shall not contain language stating or implying that the corporation is organized for a purpose other than that permitted by section 490.301 and its articles of incorporation."

Trademarks and Service Marks

You must be careful that your Iowa corporation name doesn't infringe on the trademark or service mark of another business. The easiest way to ensure you're not infringing is to perform a trademark search through Incfile. You can even register the trademark for your business if it isn't already in use.

Make sure your corporation is starting off on the right foot when it comes to intellectual property.

Let Incfile run a trademark search for you.


Register a DBA in Iowa

You may do business under a name different from your corporation's legal name. While many states refer to this as a trade name, assumed name or "doing business as" (DBA), it's a fictitious name in Iowa. You may decide to use a fictitious name for a variety of reasons.

For example, your primary business may be called Midwest Hospitality, Inc., and you have a chain called Midwest Tours. You could register a fictitious name just for that brand. You'd do that by filing a form for a Fictitious Name Resolution, or you can have Incfile do it on your behalf with our DBA service.

In order to keep your business names unique, you can also use the Iowa business entity search. You can perform an Iowa fictitious name search to find out whether any other companies are already using your desired fictitious name. We can also help you with this via our DBA name service.

Note: A trade name is not the same as a trademark. Learn more about trademark vs. DBA.
