Introduction
Have you misplaced your EIN and are now wondering, “Where can you find your Employer Identification Number?” Don’t worry—your EIN isn’t lost forever. Whether you’re filing taxes, applying for a loan, or completing official documents, you can locate your EIN quickly using the tips in this guide.
What Is an Employer Identification Number (EIN)?
An Employer Identification Number (EIN) is a nine-digit number assigned by the IRS to identify a business entity for tax and legal purposes. Think of it as a Social Security Number (SSN) for your business.
Where Can You Find Your Employer Identification Number?
1. IRS EIN Confirmation Letter (CP 575)
When you first received your EIN, the IRS sent a confirmation letter—Form CP 575. This document is the most official source for your EIN and is usually emailed, mailed, or faxed depending on your application method.
2. Your Business Tax Returns
Your EIN will be listed on any previously filed tax documents, including:
- Form 1120 (Corporation)
- Form 1065 (Partnership)
- Schedule C with Form 1040 (Sole Proprietor)
3. Official Business Documents
You may have used your EIN on these:
- Business bank account applications
- Business license applications
- Payroll setup forms
- Contracts or W-9 forms
4. Check with Your Bank or Accountant
If your EIN was used to open a business bank account, your banker may be able to retrieve it for you. Likewise, your accountant or tax preparer will likely have it on file.
5. Call the IRS
If all else fails, contact the IRS Business & Specialty Tax Line at 800-829-4933 (Monday–Friday, 7 AM–7 PM local time). Be prepared to verify your identity and business information.
Tips to Avoid Losing Your EIN Again
- Save a digital and physical copy of your CP 575
- Add the EIN to your secure business records folder
- Store a copy with your accountant or legal advisor
