What Is a 147c Letter?

An IRS letter 147c, also known as an EIN verification letter, is a letter the Internal Revenue Service (IRS) sends a company when it has lost or misplaced its Employer Identification Number (EIN) and needs to confirm what it is. A 147c letter is not a request for the IRS to create an EIN; the IRS sends it to tell you what your existing EIN is.

EIN stands for employee identification number. The IRS assigns this nine-digit number, formatted as XX-XXXXXXX. The IRS uses EINs to identify businesses for tax-related purposes.

Filing taxes, opening a business bank account, and applying for business permits are just a few examples of when you’ll need to provide your EIN. If you can’t remember your EIN number—or can’t find anything that documents it—you’ll need to request an EIN letter to obtain that information.
