The complete guide for UK residents who need a US ITIN number for LLC formation, Amazon FBA, Stripe, PayPal, US business banking, and international online business — without leaving Britain.
An ITIN (Individual Taxpayer Identification Number) is a 9-digit US tax number issued by the IRS for individuals who need to meet US tax obligations but do not have a Social Security Number — including most UK non-residents.

An official federal tax ID number from the US Internal Revenue Service.
Allows you to file taxes and operate a business; does not authorise work in the US.
