Why is my Apple Pay asking for my social security number

For information about why Apple Pay may ask for a social security number, see the following from: Identity verification for Apple Card or Apple Cash - Apple Support

Why you'll be asked for your personal data

Apple Cash services are provided by Green Dot Bank, Member FDIC, a regulated financial institution. Green Dot Bank is required by federal law to verify the identity of its customers.

To verify your identity, Green Dot Bank will request Social Security numbers and other personal information to ensure that customers are eligible to use the service.

See the thread above. Apple Pay draws funds on a bank account. Bank accounts require identification, including a social security number

WHY IS THIS HAPPENING? Suddenly asking for my childs social security number for apple pay? NOOO
