Introduction
An Employer Identification Number (EIN) is a unique, nine-digit number assigned by the IRS to businesses in the U.S. Whether you’re verifying a vendor, applying for a loan, or researching a company, you might need to know how to find the EIN of a business. Here’s how to locate this important number legally and efficiently.
1. Check the Business’s Website or Public Filings
Many businesses publish their EINs in publicly available documents, especially nonprofits and public companies.
- Visit the company’s “About Us” or “Legal” section
- Look for downloadable PDFs of annual reports, 990 forms (for nonprofits), or press releases
- SEC filings like 10-K and 8-K also contain EINs
2. Search IRS Exempt Organization Tool (for Nonprofits)
If you’re looking up a nonprofit organization, use the IRS Tax Exempt Organization Search.
- Enter the nonprofit’s name
- Review the EIN listed in their Form 990 filings
3. Use Business Databases or Credit Report Services
Several platforms provide EIN lookups for a fee or with account registration:
- Dun & Bradstreet
- LexisNexis
- Bizapedia
- Manta
- OpenCorporates
These platforms are great for accessing EINs for registered U.S. businesses.
4. Check State Government Websites
Visit the Secretary of State’s website in the state where the business is registered. Some states include EINs in public business registration records, especially for LLCs and corporations.
5. Contact the Business Directly
If you have a legitimate reason, you can request the EIN directly from the business:
- Call or email the company’s accounting or HR department
- Be ready to explain why you need the EIN (e.g., issuing a 1099)
6. Look at Tax Documents (If You’re Affiliated)
If you’re an employee, partner, or vendor, you may already have the EIN on:
- W-2 or 1099 forms
- Contracts and invoices
- Business tax returns
