✅ EIN (Employer Identification Number) is used to identify a business in the U.S. It is required for opening a business bank account, registering for Stripe/PayPal, filing business taxes, and hiring employees.
✅ ITIN (Individual Taxpayer Identification Number) is for individuals who do not qualify for an SSN but need to file U.S. taxes (e.g., freelancers, investors, or people receiving U.S. income).
If you are a non-US resident opening a company, you need an EIN, not an ITIN.
