Entity ID

An Entity ID (also known as a Document Number, Charter Number, SOS Number, or File Number depending on the state) is a unique identification code assigned to your business entity by the state government.

When you file formation documents to create an LLC or a Corporation, the Secretary of State (or equivalent state agency) generates this number to track your business in their internal database.

Entity ID vs. EIN

It is incredibly common for new business owners to confuse their state Entity ID with their Federal Employer Identification Number (EIN). They are not the same thing, and they serve completely different purposes:

• Entity ID (State Level): Assigned by the state government. It is a matter of public record and is used strictly for state-level compliance, such as filing an Annual Report or requesting a Certificate of Good Standing.
• EIN (Federal Level): Assigned by the Internal Revenue Service (IRS). It acts like a Social Security Number for your business and is highly confidential. It is used to file federal taxes, hire employees, and open a business bank account.

In short, the state tracks your business with the Entity ID, while the federal government tracks your business with the EIN.

Where to Find Your Entity ID

Because the Entity ID is a matter of public record, you can usually find it very easily.

1. State Business Search: The fastest way to find an Entity ID is to perform a business entity search on your state’s Secretary of State website. When you locate your company’s profile, the Entity ID will typically be displayed at the top of the record.
2. Formation Documents: You can find the number stamped or printed on your approved Articles of Organization or Articles of Incorporation.
3. State Correspondence: Any official mail sent to your Registered Agent from the state government will almost always reference your Entity ID.

Why Do You Need It?

You will generally need to know your Entity ID whenever you interact directly with your state’s corporate division. This includes:

• Filing your mandatory annual or biennial reports.
• Paying state franchise taxes.
• Amending your business information (like changing your business address or updating your registered agent).
• Dissolving the business.
