All California business entity information, including entity name, type, number, and formation date, is available through the California Secretary of State's business search portal. This free online database provides immediate access to the four key details you need for onboarding, compliance, or business transactions.

We'll walk you through exactly how to search the California database, where to find each piece of information, and what format each data point takes in California's system.

Information Required Where to Find It What It Looks Like Notes
Entity Name   California business search portal   "Acme Industries LLC"   Use the exact legal name as registered  
Entity Type   Business entity details page   LLC, Corporation, LP, LLP, Not-for-profit Corporation, etc   Must match California's designation  
Entity Number   Certificate or details page   C1234567 or 202312345678   Also called: Entity Number or California Corporation Number  
Formation Date   Certificate or details page   MM/DD/YYYY   Date filed with the California Secretary of State  

Access the California business entity search to look up any registered business by name or file number.

The basic search option returns results immediately for active entities. Navigate to the California Secretary of State's Business Search portal and enter your business name in the search field. California's search finds any entity containing your search term, so searching "Acme" returns "Acme Industries LLC," "Super Acme Corp," and similar matches.

For more precise results, use your complete legal name exactly as it appears. Include "LLC," "Inc.," or other designators. This is really important, as your entity might not show up in search results if you don’t enter the exact details.

If searching by entity number, remove any "C" prefix (search "1234567" instead of "C1234567").

Note: The basic search only shows active entities. If your business has been suspended or dissolved, click "Advanced Search" and adjust the status filter. Also, search results are limited to 500 matches, so if you don't see your entity, try more specific search terms.

Click the entity number in your search results to view complete details, including formation date, registered agent, and filing history.

Legal entity name (exact spelling and punctuation)

Entity type (LLC, Corporation, LP, LLP, Not-for-profit Corporation, etc.)

Entity Number (12-digit format for recent entities)

Status (ACTIVE, SUSPENDED, DISSOLVED, etc.)

Registration date (formation date for domestic entities)

Your California entity number follows the format of either seven digits (older entities, like C1234567) or 12 digits (newer entities, like 202312345678) and was assigned by the California Secretary of State when your entity was formed.

1. California business search (fastest method)

Located: Left column of search results, displayed as a blue hyperlink

Labeled as: "Entity Number"

Format: C1234567 (corporations formed before the 2000s) or 202312345678 (entities formed recently)

2. Certificate of Formation/Incorporation

Usually at the top right corner of the document

Labeled as "File Number" or "Entity Number"

Stamped or printed by the California Secretary of State

3. Annual reports and state correspondence

Appears on all official California Secretary of State documents

Used as your account identifier for Statement of Information filings

Listed on franchise tax correspondence (though franchise tax account numbers are different)

Format: 12 digits for entities formed after approximately 2001; 7-digit format with letter prefix (like C1234567) for older corporations

Example (newer format): 202312345678

Example (older format): C1234567

Pattern note: The 12-digit format typically begins with the year of formation, so entities formed in 2023 often start with "2023"

Your California entity number is different from:

Federal EIN (Employer Identification Number) from the IRS

California tax account numbers (sales tax permit number, franchise tax account number)

Business license numbers (city or county)

California Department of Tax and Fee Administration (CDTFA) account numbers

Professional license numbers

California recognizes numerous business entity types, listed exactly as shown in your business search results and formation documents.

1. California business search (most accessible)

Displayed: Prominently in search results under the "Entity Type" column

Listed as: "DOMESTIC LLC," "DOMESTIC STOCK," "FOREIGN LLC," "FOREIGN STOCK," etc.

Always shown in capital letters in California's system

2. Certificate of Formation/Incorporation

At the top of your formation document

May state "Certificate of Formation of [Entity Type]" or similar

Uses formal legal language (e.g., "Limited Liability Company" rather than "DOMESTIC LLC")

3. Annual reports (Statement of Information)

Listed in the entity information section

Cannot be changed without a formal amendment and filing

Your formation date (when the California Secretary of State officially filed and approved your business entity) appears in California business search results and on your Certificate of Formation/Incorporation.

1. California business search (easiest access)

Listed as: "Registration Date" (for domestic entities, this is the formation date)

Location: In the main search results table; also appears in the entity detail page

Note: California uses "Registration Date" even for domestic entities. This is your formation date

2. Certificate of Formation/Incorporation

Top of the document, usually in the upper right

Says "Filed" with the date stamped by the Secretary of State

Sometimes includes both the filing date and the effective date if they differ

3. Statement of Information confirmations

References original filing date

Used to determine Statement of Information due dates (due within 90 days of formation, then biennially)

Use your formation date (file date), not the effective date. California allows businesses to specify a future effective date when filing formation documents, creating two different dates:

Formation date (file date): When the California Secretary of State processed your paperwork – use this one

Effective date: When your entity officially began operations (if you specified a later date, which appears on your Certificate)

For most California entities, the formation date and effective date are the same. The business search portal displays the filing date as "Registration Date."
