An Employer Identification Number (EIN) is a unique number assigned by the Internal Revenue Service (IRS) to businesses operating in the United States. It is used to identify the business for tax purposes and is required for various business activities, such as opening a bank account, filing taxes, and hiring employees.
There are several ways to check your EIN. The most convenient method is to use the IRS’s online EIN Verification tool, which allows you to search for your EIN by business name or SSN. You can also contact the IRS by phone or mail to request a copy of your EIN assignment letter.
