What Is an EIN?
An Employer Identification Number (EIN) is a 9-digit number issued by the IRS to identify a business entity. Think of it as a Social Security number for your business.
Why You Might Need Your Company’s EIN
- Filing federal and state taxes
- Applying for business loans or grants
- Hiring employees
- Opening a business bank account
- Applying for permits or licenses
How Do I Find My Company’s EIN?
Here are the most reliable ways:
1. IRS Confirmation Letter (CP 575)
When your EIN was issued, the IRS sent you a confirmation letter. This is the most direct source.
2. Business Tax Returns
Your EIN will appear on your previous tax filings (e.g., Form 1120, 1065, or 1040 with Schedule C).
3. Bank Statements or Business Licenses
Banks and licensing agencies require EINs during account setup or registration.
4. Payroll or W-2 Forms
If you’ve issued W-2s to employees, your EIN is listed on those documents.
5. Call the IRS
You can contact the IRS Business & Specialty Tax Line at 800-829-4933. Be prepared to verify your identity and authority to access business records.
6. Contact Your Accountant or Registered Agent
If you worked with a professional or filing service like FormLLC.us, they might have a record of your EIN.
Is It Okay to Search Online for My EIN?
While some companies’ EINs are publicly listed (especially nonprofits and publicly traded corporations), small business EINs are usually not available online for privacy reasons. Stick to official and secure methods.
What If You Still Can’t Find It?
If none of the above work and you’re the responsible party, you may reapply with the IRS for a new EIN—but this is usually a last resort.
Conclusion
If you’ve ever wondered, “how do I find my company’s EIN?”—you now know where to look. Always keep a secure record of your EIN, as it’s critical for operating a compliant and smooth business.
