Repeatedly failing to verify identity for Apple Cash

My Apple Account already has my birthdate set, I double checked to make sure it was correct.

When I was under 18 I was never actually able to open an Apple Cash account—they made me verify upfront, and after 3 failed attempts, it got restricted.

Every time I call Apple Support they temporarily lift the restriction and allow me to reverify again, but it always fails and the restriction returns.

I’ve already checked my credit reports, and everything looks correct. I’m not sure about USPS format—I used the address that was autocompleted by Apple while typing my address and assumed that it was already formatted properly.

What exactly am I supposed to do on the SSA.gov site? I can’t find any place to check if my SSN was compromised.

(It also might be worth mentioning that I was able to verify my identity on various other platforms, and I was approved for a new credit card in the time Apple has failed to verify my identity)

I never got to that step, it always tells me that it failed to verify my identity after I enter my address, full SSN, etc.
