How to Find an Existing EIN Number

An employer identification number, or EIN number, is used by the Internal Revenue Service to identify businesses. When filing taxes, reporting employees' earnings or opening bank accounts, businesses must use their EIN number. If you are an employee or the owner of a company, you can locate the existing EIN of your company by entering basic information, such as the company's name, in one of several databases, or by contacting the IRS.
