EIN (Employer Identification Number)

A unique nine-digit tax identification number issued by the IRS to identify a business entity in the United States.

An EIN is essential for any US business, including those owned by non-US residents. It is required to open a US business bank account, hire employees, file tax returns, and apply for business licenses. It functions similarly to a Social Security Number (SSN) but for businesses.
