The U.S. Internal Revenue Service, or IRS, issues employer identification numbers to all corporations and other businesses that hire employees. The IRS and other government organizations use this number to identify the business and its owners for tax purposes. Many banks and financial institutions also require businesses to have an employer identification number, or EIN, to set up a new bank account. If you've lost track of your EIN or aren't sure whether you even have one, search your business records or contact the IRS for assistance.
Find Your Existing EIN
Search your business files to find your receipt from the IRS. The IRS issues a receipt for every business that applies for an EIN. This receipt shows basic business information as well as your EIN.
Call your bank or credit union and ask for assistance with finding your EIN. Banks use your EIN to identify your business and report transactions to the IRS as needed. Most banks can provide you with your EIN if you are an owner or other authorized person related to the business.
Check your business license. Most federal, state and local business or trade licenses will include your EIN.
Call the IRS and request assistance with finding your EIN. Contact the IRS Business and Special Tax Line at (800) 829-4933. The representative will ask you a few questions to verify your identity, then provide the EIN to you over the phone. If you aren't authorized to receive this number, the IRS will mail the number to the person listed on the original EIN application.
