An ein number is a nine-digit number assigned by the Internal Revenue Service (IRS) to identify a business entity. Think of it as a Social Security number for your business. The ein number is used for tax filing, reporting, and identification purposes.

Without an ein number, managing your business legally and efficiently becomes nearly impossible.
