ITIN: a tax number for a person
An Individual Taxpayer Identification Number is issued by the IRS to individuals who need a U.S. tax number but can't get a Social Security Number. You apply with Form W-7 and identity documents such as a passport.
EIN: a tax number for a business
An Employer Identification Number identifies a business entity, like a U.S. LLC, with the IRS. It's applied for with Form SS-4 and is what banks and platforms usually ask for in the company's name.
Quick comparison

- IRS form — ITIN: W-7 · EIN: SS-4
- Documents — ITIN: passport or accepted IDs · EIN: company details
- Typical use — ITIN: personal returns, treaty claims · EIN: company bank accounts, payments, filings
When you need both
Non-U.S. founders running a U.S. LLC often need an EIN for the company and an ITIN for themselves — for personal filings or when a bank or platform asks for the owner's tax number.
