it’s asking for my social security number, i put it and it still won’t let me do anything

Hello ale5100,

Thanks for connecting with us here in Apple Support Communities. Are you attempting to apply for an Apple Card or set up Apple Pay? Neither Apple Pay or Apple Cash requires a SSN. If it was either of those, this would be a phishing attempt that's designed to gain access to your personal details. We'd suggest that you connect with your bank if you've provided any banking details. See: Recognize and avoid phishing messages, phony support calls, and other scams - Apple Support

You can see how to set up Apple Pay here: Set up Apple Pay - Apple Support
