How to Locate an EIN Number


An employer identification number, or EIN, is the nine-digit tax identification code issued to a business by the Internal Revenue Service. The number is used by the federal government to identify a particular business. You need your business's EIN if you are opening a bank account; applying for a state or local business license; or acting as a contractor for another organization.
Additionally, an individual filing federal or state taxes online must provide the EIN along with all other information contained on Forms W-2.

Things You'll Need

  • Company name
  • Company owner name
  • State-issued photo identification card
  • Form W-2
  • If you are an employee of the company whose EIN you seek, look in Section B, "Employer Identification Number (EIN)," of the Form W-2 provided to you by your employer.

  • If you are seeking an EIN on behalf of the company to which the EIN is assigned, look on your copies of your most recent tax return documents submitted to the Internal Revenue Service. The EIN is the number on the top of your tax return that identifies your business.

  • Call a bank with which you have a business account. When you open a business account with a financial institution, you must provide the bank with your EIN. You may have to visit the branch at which you opened your account and produce your state-issued photo identification card to prove that you are authorized to receive such information.

  • Check the business file in your office for a copy of the notice you received from the IRS when you first applied for your EIN.

  • Telephone the Business & Specialty Tax Office of the IRS by dialing 800-829-4933. A representative will request identifying information, including your name and address, and will then provide you with your EIN. You must be the person authorized to receive such information for your business in order to locate an EIN number from the IRS Business & Specialty Tax Office.
