Federal Employers Identification Number
If you plan on opening a bank account under your corporate name, most banks will require that your corporation have a Federal Employers Identification Number. A Federal Tax Identification Number (also known as a "95 Number" or "EIN Number" ) is a number assigned to a corporation or L.L.C. by the Federal Government for purposes of taxation. The Federal Tax ID Number is to a corporation or L.L.C. as a Social Security Number is to an individual. Most banks require that a corporation or L.L.C. obtain a Federal Tax Identification Number as a prerequisite to opening a bank account regardless of whether the company will have employees.
