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 select cannot be in use by any other business in the state. This is why it's so important to perform a California Secretary of 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 corporation name to be unique. It also cannot be similar to the name of another business 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, California Department of Insurance, California Highway Patrol, 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 California Business Names

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

For example, per the state's Corporation Code Title 1, Division 1, Chapter 2, § 201:

The Secretary of State shall not file articles setting forth a name in which “bank,” “trust,” “trustee,” or related words appear unless the certificate of approval of the Commissioner of Business Oversight is attached thereto. This subdivision does not apply to the articles of any corporation subject to the Banking Law which is endorsed by the approval of the Commissioner of Business Oversight.

The name of a corporation shall not be a name that the Secretary of State determines is likely to mislead the public and shall be distinguishable in the records of the Secretary of State from all of the following:

  • The name of any corporation.
  • The name of any foreign corporation authorized to transact intrastate business in this state.
  • Each name that is under reservation pursuant to this title.
  • The name of a foreign corporation that has registered its name pursuant to Section 2101.
  • A name that a foreign corporation has assumed under subdivision (b) of Section 2106.
  • A name that will become the record name of a domestic or foreign corporation upon a corporate instrument when there is a delayed effective or file date.

Trademarks and Service Marks

You must be careful that your California 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 Bizee. If the trademark isn't already in use, you can even register it yourself.

Register a California DBA

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

For example, your primary business may be called OC Hospitality, Inc., and you have a chain called OC Catering. You could register a fictitious name just for that brand. You'd do that by registering your fictitious name with the Clerk of Superior Court of the county where your corporation is located in, or you can have Bizee do it on your behalf with our DBA service.

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

Note: A trade name is not the same as a trademark.

Register Your Business Name With the CA Sec State

You’ve performed a California SOS business search, checked availability, followed the naming rules, and determined whether you need a fictitious name. Now you can register your corporation name in one of two ways.

If you don’t want to form your corporation right away, you can reserve the business name. You'll do this by submitting a Name Reservation Request form and filing it with the CA Sec State. The name will be reserved for 60 days. If you're starting your business right away, you don't need to reserve a name.

If you’re ready to start your corporation, you can indicate your chosen business name when you file your Articles of Incorporation with the CA Sec State. Or you can have Bizee do this for you.
