The Federal Employer Identification Number (FEIN), also known simply as an EIN, is a unique nine-digit number assigned by the IRS to identify a business entity. Whether you’re dealing with vendors, filing forms, or verifying a nonprofit, you may need to locate a company’s FEIN.
Here’s a practical guide on how to find the FEIN number for a company, legally and reliably.
What Is a FEIN Number?
A FEIN (Federal Employer Identification Number) is issued by the IRS for business identification. It works similarly to a Social Security Number but is used for corporations, LLCs, partnerships, and nonprofits.
Legal Ways to Find a Company’s FEIN
1. Check the Company’s Website or Public Disclosures
Some companies, especially nonprofits or large corporations, may list their FEIN on:
- Official websites
- Tax or donation receipts
- “About Us” or investor relations pages
Nonprofits are required to make certain tax documents public, and these documents often include their FEIN.
2. Search IRS Exempt Organization Database (for Nonprofits)
Use the IRS Tax Exempt Organization Search tool:
https://apps.irs.gov/app/eos/
You can find a nonprofit’s FEIN on its Form 990 filings, which are public records.
3. Check SEC Filings for Public Companies
If the business is publicly traded, visit the U.S. Securities and Exchange Commission’s (SEC) EDGAR database:
https://www.sec.gov/edgar.shtml
FEINs are often included in annual or quarterly reports.
4. Contact the Company Directly
If you have a legitimate business need (e.g., issuing a 1099 or processing payroll), reach out to the company and request their FEIN directly.
5. Use a Business Information Database
Third-party platforms like:
- Dun & Bradstreet
- LexisNexis
- Manta
- OpenCorporates
…may include FEINs for registered businesses—note that some may charge a fee.
6. Look on Invoices, Contracts, or W-9 Forms
If you’ve previously done business with the company, you may already have their FEIN on:
- Invoices
- Contracts
- IRS Form W-9 (Request for Taxpayer Identification Number)
Important Note on Privacy
Is it legal to look up a company’s FEIN?
Yes, but only when done through public records or with permission. FEINs are not freely searchable for private companies due to privacy laws and identity protection rules.
