Learn About Finding Company Employer Identification Numbers

Understanding What an Employer Identification Number Is

An Employer Identification Number, commonly called an EIN, is a nine-digit code issued by the Internal Revenue Service (IRS). The format looks like this: XX-XXXXXXX. Think of it as a Social Security number, but for businesses instead of people. Just as individuals use Social Security numbers for tax purposes and financial matters, businesses use EINs to identify themselves to the federal government.

The IRS created the EIN system to track business tax information, employment records, and other critical financial data. When a business has an EIN, the IRS can monitor tax filings, payroll records, and business income. This nine-digit number appears on business tax returns, employment paperwork, and financial documents.

EINs serve several important functions in the business world. They allow the IRS to match business income reports with individual tax returns. They help employers report wages paid to workers on W-2 forms. Banks and financial institutions use EINs to open business accounts and process loans. Vendors and contractors ask for EINs to verify that businesses are legitimate entities.

According to IRS data, approximately 33 million businesses in the United States have active EINs. This number includes sole proprietorships, partnerships, corporations, nonprofits, and other business structures. The EIN system has been in place since 1962, making it one of the longest-standing business identification systems in the country.

Not every business needs an EIN. Sole proprietors without employees may operate using only their Social Security number. However, businesses that hire employees, form partnerships or corporations, or operate as nonprofits must obtain an EIN. The number itself costs nothing to obtain from the IRS.

Practical Takeaway: An EIN is a nine-digit identifier that the IRS uses to track business tax information. Understanding what an EIN is and why businesses need one is the first step in learning how to locate or obtain one.

Where to Find a Company's Employer Identification Number

Finding a company's EIN requires knowing where to look. Several resources contain this information, and different methods work depending on what type of company you are researching and what access you have to company records.

The most direct source is the company itself. Many businesses display their EIN on official documents. You can find it on business tax returns, W-2 forms sent to employees, 1099 forms given to contractors, and loan documents. If you work for a company or receive income from one, check the paperwork they sent you. The EIN is often printed in the upper right corner of W-2 and 1099 forms, right next to the company's name and address.

Business bank statements frequently show the EIN. If you have access to company banking records or financial statements, the EIN typically appears at the top of these documents. Annual financial reports that public companies file with the Securities and Exchange Commission (SEC) include the EIN. These reports are available on the SEC's website through their EDGAR database, which is searchable and free to use.

The IRS offers a tool called the Tax Exempt Organization Search. This resource allows anyone to search for nonprofit organizations and view their EINs. You can access this tool on the IRS website at irs.gov. Simply enter the organization's name or EIN, and the database returns information about that nonprofit, including its EIN, address, and tax status. This tool covers over 1.5 million registered nonprofits across the United States.

State business registration databases are another valuable resource. Each state maintains records of businesses registered within that state. Many states offer free online searchable databases where you can look up a company's registration information, which includes the EIN. The specific website varies by state, but most can be found through your state's Secretary of State office or Department of Revenue.

Credit reporting agencies and business credit databases like Dun & Bradstreet sometimes list company EINs. These services are not always free, but they provide detailed business profiles that include EINs and other identifying information. Business directories and chambers of commerce occasionally post EINs as well, particularly for member companies.

Practical Takeaway: Check company documents first, then explore state business databases, the IRS Tax Exempt Organization Search, and SEC filings to locate an EIN. Each source works best depending on the type of company you are researching.

How to Search the IRS Tax Exempt Organization Database

The IRS Tax Exempt Organization Search is one of the most straightforward ways to find EINs for nonprofit organizations. This free, publicly available tool contains information about organizations that have received tax-exempt status from the federal government. Understanding how to use this database will help you locate nonprofit EINs quickly and accurately.

To begin a search, visit the IRS website and navigate to the Tax Exempt Organization Search page. You do not need to create an account or provide personal information. The search tool has several fields where you can enter information about the organization you are looking for. You can search by the organization's name, its EIN (if you already have part of it), its city, state, or ZIP code. The more specific information you provide, the narrower your search results will be.

When searching by name, you can enter the full name or just a portion of it. For example, if you are looking for "American Red Cross," you could search for just "Red Cross" and still find the organization. The search tool returns all organizations that match your criteria. Each result shows the organization's legal name, EIN, street address, city, state, ZIP code, and tax status.

The database includes Form 990 filings for many organizations. Form 990 is the annual tax return that nonprofits must file with the IRS. These forms contain detailed financial information, including the organization's EIN, revenue, expenses, and mission statement. You can often download Form 990 documents directly from the search results, giving you access to comprehensive financial information about the nonprofit.

The IRS updates this database regularly, though there may be a slight delay between when an organization files paperwork and when it appears in the search tool. According to IRS records, the Tax Exempt Organization Search contains over 1.5 million active organizations. Approximately 75,000 new nonprofits receive tax-exempt status each year in the United States, though the database does not update in real time.

If your search returns no results, consider these troubleshooting steps: try searching with different variations of the organization's name, search by city and state instead of organization name, or search with just a portion of the name. Some very new nonprofits may not yet appear in the database. If you believe an organization should be listed but is not, contact the IRS directly or check the organization's official website to verify its EIN.

Practical Takeaway: Use the IRS Tax Exempt Organization Search by entering an organization's name, city, or state to locate its EIN and access its Form 990 filings. This resource is free and works well for searching nonprofit organizations.

Using State Business Records to Find Company EINs

State business databases provide another avenue for locating company EINs, particularly for for-profit businesses. Each state maintains records of businesses that register within its borders. These records typically include the EIN along with other company information. Learning how to search state databases expands your options for finding the information you need.

Most states maintain searchable online databases through their Secretary of State office. These databases contain information about corporations, limited liability companies (LLCs), partnerships, and other registered business entities. To access a state database, go to your state's Secretary of State website and look for a "business search" or "corporation search" option. Some states call this the "Business Entity Database" or "Uniform Commercial Code Search."

Searching a state database typically involves entering the company name or, in some cases, a business identification number assigned by the state. The results show the business's legal name, principal address, type of business structure, and in many cases, the EIN. Some states display additional information such as the date the business registered, the names of owners or managers, and the business's status (active, inactive, dissolved, etc.).

Different states organize their databases in different ways. For example, California's Secretary of State maintains a "Business Search" tool on its website that is free and allows searches by business name or entity number. Texas provides a similar service through its Secretary of State website. New York's Division of Corporations maintains a database called "NYS
