An Employer Identification Number (EIN) is essential for business tax filings, opening a bank account, or hiring employees. But what if you’ve misplaced it or need to find the EIN of another business? Here’s how to find an EIN quickly and legally.
1. Check Your Business Records
If you’re looking for your own EIN, start with:
- IRS confirmation letter (CP 575)
- Previous tax returns
- Bank account applications
- Business licenses or permits
2. Call the IRS
If you can’t find your EIN in your records, call the IRS Business & Specialty Tax Line at 800-829-4933 (Mon–Fri, 7 AM–7 PM local time). You’ll need to verify your identity.
3. Look It Up on the IRS Exempt Organizations Tool
If you’re searching for an EIN of a nonprofit organization, use the IRS Tax Exempt Organization Search Tool.
4. Search SEC Filings or Business Databases
For publicly traded companies, their EINs are often listed in SEC filings (like 10-K forms). You can also use business lookup tools from state websites or private EIN lookup services.
5. Contact the Company Directly
If you’re trying to verify the EIN of another business, the most reliable method may be to ask the company. Many businesses include their EIN on invoices or official documents.
Key Takeaway
When wondering how to find an EIN, start with internal documents or call the IRS. For other businesses, use nonprofit databases, SEC filings, or direct contact.
