If you’re working with a business, filing a 1099, or conducting due diligence, you might ask: How do you find a company’s EIN (Employer Identification Number)?
An EIN is a unique nine-digit number issued by the IRS to identify a business for tax purposes. While it’s not always public, there are legal and legitimate ways to look it up.
1. Check the Company’s Website or Invoices
Some companies publish their EIN on official documents such as:
- Invoices
- W-9 forms
- Contracts
- Press releases or footers of official pages
If you’re working with the business directly, request a Form W-9, which should list their EIN.
2. Search SEC Filings (For Public Companies)
If the company is publicly traded, visit the SEC EDGAR database and search by business name. EINs often appear on official filings such as:
- 10-K
- 8-K
- S-1
3. Use Business Entity Search Tools
Some states provide online business lookup tools. Visit your state’s Secretary of State website and search for the company. The EIN might not be shown, but contact info may help you request it directly.
4. Nonprofit EIN Lookup
For nonprofits, use the IRS Tax Exempt Organization Search Tool. Most nonprofits are required to publicly share their EINs.
5. Third-Party EIN Databases
Some online databases, like:
- Melissa Data
- Guidestar (for nonprofits)
- OpenCorporates
may offer EINs for registered businesses—though access may be limited or paid.
6. Ask the Business Directly
The easiest and most reliable way? Contact the business and ask for their EIN, especially if you need it for tax or compliance purposes.
