This type of search provides you with information about corporations, limited liability companies (LLCs), and limited partnerships (LPs).

Step 1:

Go to the California Secretary of State webpage and select the search type you want to use: Corporation Name, LP/LLC Name, or Entity Number.

Step 2:

Enter the entity name or number in the Search Criteria box.

Tip: If you are searching for a corporation by entity number, you must enter the letter "C" followed by the 7 digit entity number. If you are searching for an LP or LLC by entity number, you only need to enter the 12 digit entity number.

Step 3:

Select the Search Filter you want to use. In this option, you can select "Exact" to search for the exact name of the entity, or you can select "Begins With" to search for all options that begin with the first word or two of the entity's name, including entities that have additional words in the name. Once you have selected the appropriate search filter, click on "Search."

Step 4:

On the results page, you will see a list of the entities that match your search with the business's number, date filed, status, name, and registered agent. Choose the entity you wish to view by clicking on the black bold link.

Step 5:

You can now view the details of the entity you are researching, which includes (but is not limited to) the entity's name, number, date of filing, status, state of formation, principal office address, and registered agent, as well as the registered agent's address.

All LLCs and corporations in California must have unique names. In order to check that the name you want to use is available, you can conduct a business name search.

Step 1:

You can use the California Secretary of State's Business Search page to check if there are any businesses with the name you want to use. However, this search option is not meant to serve as a formal name search, but as a preliminary search option only.

Step 2:

As a corporation's name may not be the same or too similar to any existing Californian corporation, it is best if you check that the name you wish to use is available. To do so, you can mail a completed Name Availability Inquiry Letter to the California Secretary of State's office in Sacramento. You can find a PDF copy of this letter here.

Step 3:

You can reserve a name for 60 days by completing and mailing a Name Reservation Request Form. All fees and instructions are listed on the form, which you can find here.

Step 4:

You will need to review California's business naming rules to ensure that your chosen name will be approved. You can find a detailed list of these rules and regulations here.
