The purpose of Form SS-4, Application for Employer Identification Number (EIN), is to obtain a Federal Tax Identification Number from the IRS. The EIN can be applied for by using the IRS’s online application, by faxing, by mailing or by calling the IRS Business and Specialty Tax Line at (800) 829-4933. If you lose your original copy of the form, there is no method for retrieving a physical copy. The only thing the IRS will supply is a copy of the EIN assignment letter.

Lost or Forgotten EIN

If your company’s EIN is unknown, there are several ways to retrieve it. Check the company files for communications from the IRS, including the original notice containing your EIN. If you applied online, you might have saved a copy of the letter to your computer’s hard drive. Contact any bank or financial institution your company did business with as they are required to have your company's EIN before allowing the company to open an account. Look at old corporate tax returns, paycheck stubs or Form W-2s for the EIN. If you are still unable to locate the EIN, contact the IRS through its Business and Specialty Tax Line.
