Follow CA Corporation Naming Guidelines

Most business filing rejections are due to business name issues. This happens when the name isn’t distinguishable enough from other business names or when the name doesn’t meet state guidelines.

California Corporation Naming Rules:

  • Your name must be distinguishable from the name of any existing business in California and must not be the same or deceptively similar to an existing corporate name. This includes California reserved names. We will help with this step in the search for your business name section below.
  • The name of your corporation must not be one likely to mislead the public. A proposed name is likely to mislead the public in the following circumstances:
  • It implies the corporation is a government agency
  • It implies the corporation is a professional corporation under the Moscone-Knox Professional Corporation Act when it is not
  • It uses a misleading identifier, e.g. includes the abbreviation LLC
  • It creates the false implication that the corporation’s purpose is to be an insurer when it is not

CA Secretary of State Business Entity Search

If you need to search existing business entities in California, visit the California Secretary of State Business Search and include any info you have on the business in the search bar. You can also do an advanced search for any business entity name.

California Business Entity Search FAQs

The easiest way to find out who owns a business in California is to search for the business’s filings with the California Secretary of State. Businesses are required to file certain documents with the Secretary of State, including their Articles of Incorporation (if they are a corporation) or Articles of Partnership (if they are a limited partnership) or Articles of Organization (if they are an LLC). These documents will list the names and addresses of the business’s owners and status of the business entity.

An advanced search for California Business Entities can be performed by going to the Secretary of State’s website and clicking on the “Businesses” link. From there, you will be able to select “Entity Name” from the drop-down menu and enter your desired search criteria.
If you are looking for a specific business entity, you may want to use the advanced search feature to narrow your results. For example, if you know the entity’s filing number, you can enter it in the “File Number” field to retrieve the filings associated with that number.

You can also use advanced search to find businesses that have been formed in a specific city or county. Simply select the appropriate option from the “Jurisdiction” drop-down menu and enter the desired location.

How do I name a small business?

Naming a small business is often a do-it-yourself job. Small business startup budgets usually won’t support hiring someone to help name your business. For easy step-by-step instructions on naming your small business, visit our How to Name a Business guide.

How do I come up with a catchy business name?

The first step to naming your business is figuring out what business structure you will use for your new company. After that, you will brainstorm at least 4-5 possible names. The more you brainstorm the better. Once you have some names, you can test the names against best practices, name availability, and state guidelines.

Can I put the word “company” in my business name?

Yes, you can. Neither the term “company” nor any of its abbreviations has any legal connotations. A company is simply an association of individuals.

Do I have to write “LLC” after my company name?

If you choose to use a limited liability company structure for your new business, most states will require that you use LLC after the name. You can also use the full term limited liability company.

If you are marketing your business, you usually don’t have to use LLC after the name.
