EIN Lookup — find a US company by its EIN (Tax ID)
Enter an Employer Identification Number to see which company public records list it for. EINs are public only for some companies — nonprofits, SEC filers, and companies whose Florida or Texas records include one — so a number we can’t find may still be valid.
Where we look for an EIN
We show a company only when one of these sources lists exactly the number you entered. Nothing is guessed.
- IRS exempt organizations — charities, foundations and other tax-exempt organizations, listed by EIN.
- SEC EDGAR — public companies and other SEC filers; the EIN is on the cover page of their reports, and we confirm it against the filer’s SEC profile.
- Florida corporate filings — the EIN the company entered on its own filings. It is self-reported and not checked by the state.
- Texas franchise-tax accounts — the Texas taxpayer number is often built from the EIN, so many companies registered in Texas can be matched.
- U.S. Department of Labor Form 5500 filings — employers that sponsor a retirement or health benefit plan file it with their own EIN, in every state. When several company names use one EIN (a parent company, a PEO or a plan administrator filing for others) we say so.
Other state registries generally do not publish EINs, so a private company registered elsewhere is usually found by searching its name.
Find a company’s EIN
Going the other way — from a name to an EIN — works only when the company has made the number public. Where to look, from most to least reliable:
- 1
Ask the company for Form W-9
A signed Form W-9 gives the legal name and EIN the business reports to the IRS. It is the normal way to get an EIN before you pay a vendor or contractor.
- 2
Public companies: the SEC filing cover page
Every 10-K and 10-Q shows the “I.R.S. Employer Identification No.” on its first page. Find the company’s filings with SEC EDGAR search.
- 3
Nonprofits: IRS Tax Exempt Organization Search
The IRS Tax Exempt Organization Search lists exempt organizations with their EIN.
- 4
Nonprofits: Form 990
A nonprofit’s annual Form 990 shows its EIN at the top. ProPublica Nonprofit Explorer lets you search 990s by name.
- 5
State filings, rarely
A few states keep the EIN a company entered on its filings (Florida is one). Most state business registries do not show it.
There is no public directory of EINs for private companies. More detail in our guide How to Look Up a Company by EIN.

FAQ
Which companies can be found by EIN?
Only those whose EIN appears in a public record. The IRS does not publish EINs for most private companies, and no public database covers them all. This tool finds a company when its EIN appears in a public record: IRS tax-exempt organization data, SEC filings, Florida corporate filings, Texas franchise-tax accounts or employee-benefit-plan filings with the U.S. Department of Labor (Form 5500).
Is this EIN number lookup free?
Yes. Looking up an EIN and opening the matching company page is free and needs no account. A free account adds a full report of one company — everything on its page.
Why did my EIN return no result?
Most likely the company is a private business that has never put its EIN in one of the public records we search. Search the company by name instead, or ask the company for a signed Form W-9.
How do I find a company’s EIN?
Ask the company for Form W-9. For public companies the EIN is on the cover page of SEC reports; for nonprofits it is in the IRS Tax Exempt Organization Search and on Form 990. Most state registries do not show it.
Do you show EINs of individuals?
No. This tool only matches EINs that appear in public business and nonprofit records. It does not search people, and sole proprietors who use their Social Security number have no EIN to find.
Is an EIN the same as a tax ID number?
An EIN (Employer Identification Number, also called FEIN or federal tax ID) is the 9-digit number the IRS assigns to businesses, written 12-3456789. States issue their own tax account numbers, which may or may not be based on it.
Know the company name?
Search state registrations, SEC filings, sanctions lists and court records by name.
