Start Now →What works for which company
| Company | Where to look |
|---|---|
| Any business you pay or will pay | Ask for a Form W-9 |
| Public company | Its SEC filings. Our EIN lookup searches them |
| Nonprofit | Its Form 990, or a nonprofit EIN lookup |
| Florida company | Florida records often include it. See Sunbiz EIN |
| Your employer | Box b of your W-2. See how to find your employer’s EIN |
| Your own company | Your IRS letter or a filed return. See how to find your LLC’s EIN |
Other places it may appear
- Invoices and contracts. Some companies print the number on them.
- A 1099 or W-2 you received from the company.
- Credit reports. Paid business credit reports sometimes list it.
What will not work
The IRS will not give out another company’s number. Most state business searches do not hold it either, though they confirm the company exists. Try our business search for that. Be careful with paid sites that promise any company’s EIN, since no complete database exists.
Checking a number you were given
Our EIN checker tests the format, which does not prove the number is real. See how to verify an EIN, and TIN matching if you file information returns.
Quick answers
Can the IRS tell me another company's EIN?
No. The IRS only gives a number to someone authorized for that business.
Is a company's EIN public?
Not generally, but it can appear in public records such as nonprofit filings and public company filings.
Can I search by EIN to find a company?
In some records. Our free EIN lookup checks Florida, Texas and nonprofit records by number. Most companies appear in none of them.
How do I verify an EIN I was given?
Compare it with a W-9 and the company's name. A payer eligible for the IRS TIN Matching program can check the name and number together.
