An EIN (Employer Identification Number) is a 9-digit number issued by the U.S. Internal Revenue Service (IRS) to identify businesses. For companies operating in the U.S. or engaging in business with the U.S., an EIN is required to file tax returns, open business bank accounts, hire employees, and identify the company in official documents.
