EIN Privacy
Are EIN Numbers Public? Privacy, Records, and Lookups Explained (2026)
An EIN is not fully public like a company name, but it is not a protected secret either. Whether it is public depends on your entity type. Here is exactly where EINs appear and how to protect yours.
Last updated: July 10, 2026
An EIN is not fully public the way a company name is, but it is not a protected secret either. Nonprofits' EINs are public (IRS Tax Exempt Search, Form 990). Public companies' EINs appear on SEC filings. Private companies' EINs are generally not in a free public database, though they appear on W-2s, W-9s, business licenses, and some filings. Looking up a company's EIN is legal; using one fraudulently is not.
"Is my EIN public?" has no single yes-or-no answer. The right answer depends on what kind of entity holds the EIN. A nonprofit's EIN is deliberately public; a private LLC's EIN is not.
This guide explains how "public" changes by entity type, where a private company's EIN legitimately appears, which free lookup sources actually work, when looking up an EIN is legal, and how to protect your own. For the mechanics of finding a number, see EIN lookup.
Is an EIN Public? It Depends on the Entity Type
Whether an EIN is public depends entirely on the entity. Nonprofits and public companies must disclose their EINs by law. Private companies do not, and their EINs stay out of free public databases.
| Entity type | Is the EIN public? | Where it is disclosed |
|---|---|---|
| Nonprofit / tax-exempt | Yes | IRS Tax Exempt Search, Form 990, ProPublica |
| Public company | Yes | SEC EDGAR filings (10-K, 10-Q) |
| Private LLC / corporation | No free public database | W-9, W-2, 1099, some state filings |
| Sole proprietor | No | Shared documents only |
The reason is transparency law. Tax-exempt organizations receive public benefits, so the IRS requires their finances — including the EIN on Form 990 — to be public. Note that a nonprofit's EIN being public does not mean the EIN grants exemption — see EIN vs tax-exempt number. Public companies must disclose to protect investors. A private LLC has no such obligation, so its EIN appears only where the business chooses to share it.
Where Private EINs Appear
Where Does a Private Company's EIN Legitimately Appear?
A private company's EIN appears on documents the business shares with specific parties, not in a public registry. Each of these is a normal, legitimate disclosure.
- Form W-9 — provided to clients so they can issue a 1099. The EIN replaces the owner's SSN.
- Form W-2 and 1099 — the employer's or payer's EIN appears on tax documents issued to workers.
- Credit and loan applications — lenders collect the EIN to pull the business credit file.
- Business licenses and permits — some state and local filings list the EIN, and a few are searchable.
- Bank and vendor accounts — the EIN identifies the business on financial paperwork.
None of these puts the EIN in a free public database. They expose it only to the counterparties who need it. This is why a private EIN is "semi-private" — shared by necessity, but not broadcast.
Which Free Sources Actually Work for EIN Lookup?
Three free sources reliably return EINs, and each covers a specific entity type. No free source covers private companies.
| Source | Covers | What it shows | Cost |
|---|---|---|---|
| IRS Tax Exempt Organization Search | Nonprofits | EIN, status, filings | Free |
| SEC EDGAR | Public companies | EIN on 10-K, 10-Q, other filings | Free |
| ProPublica Nonprofit Explorer | 990 filers | EIN from published Form 990 | Free |
To find a nonprofit's EIN, search IRS Tax Exempt Organization Search at irs.gov or look up its Form 990 on ProPublica. To find a public company's EIN, open its latest 10-K on SEC EDGAR — the EIN is on the cover page. For a private company, there is no free database; you request the EIN directly or read it from a shared document. The full method is in EIN lookup, and employees can use find your employer's EIN without a W-2.
Legality
Is It Legal to Look Up a Company's EIN?
Yes. Looking up a company's EIN for a legitimate purpose is legal. An EIN is a business identifier, not a protected personal secret, and businesses routinely exchange EINs for tax and verification reasons.
Legitimate reasons to look up an EIN include:
- Verifying a vendor or contractor before payment.
- Preparing a 1099 for someone you paid $600 or more.
- Confirming a nonprofit's tax-exempt status before donating.
- Checking a business partner's registration details.
What crosses the legal line is misuse: impersonating a business, filing false tax returns, or opening accounts in another company's name. The lookup is legal; fraudulent use of the number is a crime. Guarding against misuse is why you should verify an EIN belongs to the business you expect before relying on it.
Common EIN Privacy Myths vs the Reality
Four myths drive most EIN privacy confusion. Each has a specific, verifiable reality that corrects it.
| Myth | Reality |
|---|---|
| "Anyone can look up any EIN in a public database." | Only nonprofit and public-company EINs are in free databases. Private EINs are not. |
| "My EIN must stay secret like a password." | An EIN is a business identifier you share on W-9s and 1099s. It is not a password. |
| "Someone with my EIN can drain my bank account." | Banks require identity verification and documents. The EIN alone opens nothing. |
| "Giving clients my EIN is risky." | Providing an EIN on a W-9 is standard, and it protects your SSN by replacing it. |
The pattern is consistent: an EIN sits between fully public and fully private. Treat it as sensitive business information — shared deliberately with legitimate parties, guarded against scammers, but not hidden like a Social Security Number. The genuine risk is business identity theft, which requires the EIN plus other stolen data, not the number by itself.
How Do You Protect Your Own EIN?
Protect your EIN by sharing it only when a legitimate party needs it and by watching for scams. The number alone is low-risk, but combined with other stolen data it enables business identity theft.
Share selectively
Give your EIN only to banks, clients issuing 1099s, lenders, and licensing agencies. Use it instead of your SSN on W-9s to protect your personal identifier.
Verify who is asking
EIN phishing scams impersonate the IRS or banks to harvest business details. The IRS does not request your EIN by unsolicited email or text. Confirm the requester before responding.
Monitor your business credit file
Watch for accounts or inquiries you did not authorize. Unexpected activity on your EIN's business credit file is an early sign of fraud.
Secure your documents
Keep the CP 575 EIN confirmation letter, formation documents, and tax filings secure. These pair with the EIN to enable account opening.
An EIN on its own cannot drain a bank account or open credit, because every institution requires identity verification and documents beyond the number. Treat it like a business phone number: not a secret, but not something to post publicly.
Frequently Asked Questions
Can anyone look up my business's EIN?
It depends on your entity type. Anyone can look up a nonprofit's EIN through IRS Tax Exempt Organization Search or a public company's EIN through SEC filings. A private company's EIN is not in any free public database, so it cannot be looked up the same way — it appears only on documents you share, like W-9s, 1099s, and some state filings.
Is it illegal to find a company's EIN?
No. Looking up a company's EIN for a legitimate purpose — verifying a vendor, preparing a 1099, or confirming a nonprofit — is legal. EINs are business identifiers, not protected personal secrets. What is illegal is using an EIN fraudulently: impersonating a business, filing false returns, or opening accounts in another company's name.
Where can I find a nonprofit's EIN for free?
Use IRS Tax Exempt Organization Search at irs.gov, which lists registered nonprofits and their EINs, or ProPublica Nonprofit Explorer, which publishes Form 990 filings that show the EIN. Both are free. A nonprofit's EIN also appears on its Form 990, which every tax-exempt organization must make publicly available on request.
What can someone do with just my EIN?
Very little on its own. An EIN alone cannot drain a bank account or open credit, because banks and lenders require identity verification, formation documents, and often the owner's SSN or ITIN. The real risk is EIN combined with other stolen data used for business identity theft or fraudulent filings. Guard the number, but it is low-risk in isolation.
How do I protect my EIN from fraud?
Share your EIN only when a legitimate party needs it — banks, clients issuing 1099s, and licensing agencies. Verify who is asking before responding to unsolicited requests, since EIN phishing scams are common. Monitor your business credit file for unexpected accounts, and keep formation documents and the CP 575 confirmation letter secure.
Are private-company EINs public records?
No. A private company's EIN is not published in a free public record or searchable government database. It appears on documents the business shares — W-9s, W-2s, 1099s, credit applications, and some state business filings. Third-party paid databases may hold private EINs, but there is no free public registry the way there is for nonprofits.
Is there a free database for EIN lookup?
Free EIN databases exist only for specific entity types. IRS Tax Exempt Organization Search covers nonprofits. SEC EDGAR covers public companies. ProPublica Nonprofit Explorer covers 990 filers. There is no free universal database for private-company EINs. For private companies, you request the EIN directly or find it on a shared document.
Do I have to give my EIN to clients?
Yes, when a client needs to issue you a 1099. US businesses that pay you $600 or more for services request a completed Form W-9, which includes your EIN, so they can report the payment to the IRS. Providing your EIN on a W-9 is standard and legitimate. It replaces your SSN on the form, which improves your privacy.
Can I keep my EIN private as a business owner?
Partly. You control who you share it with, and using an EIN instead of your SSN on W-9s and business documents protects your personal identifier. You cannot make a nonprofit or public-company EIN private, because disclosure is required by law. For a private company, the EIN stays out of free public databases as long as you share it selectively.
