An Employer Identification Number (EIN), also known as a »Tax ID», is a unique nine (9) digit number issued by the Internal Revenue Service (IRS) that is used to identify a company for tax purposes.

It is important for your company to have an EIN, as it will allow you to protect your personal assets, have access to the US banking system through the opening of bank accounts, file and pay taxes, apply for business licenses, hire employees, among others.
