Introduction
If you’re a business owner or researching another company, you may wonder: Are EIN numbers public? Understanding how EINs work, who can access them, and whether they are publicly available is essential for privacy and compliance.
What Is an EIN?
An Employer Identification Number (EIN) is a 9-digit number issued by the IRS to identify businesses for tax and reporting purposes. It functions similarly to a Social Security Number—but for businesses.
Are EIN Numbers Public?
Yes, in some cases, EIN numbers are public information. Certain business EINs can be accessed through:
- Public records (e.g., nonprofit 990 forms)
- Business registrations with state authorities
- SEC filings or government contract databases
However, the IRS does not publish a central directory for all EINs. Most businesses are not required to disclose their EIN to the public unless part of a regulatory or contractual obligation.
Where Can You Find a Public EIN?
You might be able to find a business’s EIN through:
- IRS Exempt Organization Search (for nonprofits)
- Secretary of State websites (some states display EINs)
- SEC EDGAR database (for publicly traded companies)
- Business credit reports (from agencies like Dun & Bradstreet)
For private LLCs or sole proprietorships, EINs are usually not publicly posted online.
Can Someone Use Your EIN?
While EINs are public in limited cases, they are not considered confidential like SSNs. Still, EIN misuse (like tax fraud) is illegal. If you’re concerned, monitor your business credit and use secure channels when sharing your EIN.
How to Protect Your EIN
- Avoid publishing it on your website unless required
- Use secure methods when submitting documents
- Monitor business credit for suspicious activity
- Apply for an EIN separate from your SSN (especially for sole proprietors)
Conclusion
Are EIN numbers public? They can be—especially for nonprofits, corporations, and businesses involved in public filings. However, for most small private businesses, EINs are not easily searchable online.
