What is an EIN?
An Employer Identification Number (EIN) is a unique nine-digit tax ID assigned by the IRS to identify businesses for tax purposes. Also known as a Federal Tax Identification Number, it's like a Social Security Number for your business. It's used for filing taxes, hiring employees, opening bank accounts, and more.

Yes, if:
