Individual Enrollment Fails with "Unknown Error Occurred" — Phone Number and Payment Verified

Hello,

I'm trying to enroll in the Apple Developer Program as an individual and consistently receive this error when submitting my enrollment:

"We are unable to process your request. An unknown error occurred."

Troubleshooting already completed:

  • Apple ID region: United States
  • Added and verified a US-based trusted phone number to my account (previously had none) — issue persists
  • Payment method on file matches my account region
  • Tried in a fresh/private browser window
  • Two-factor authentication is enabled and in good standing
  • No pending agreements or existing enrollment found in my account

This error occurs after I accept the Terms and Conditions agreement, which makes it impossible for me to troubleshoot further on my end.

I have a hard external deadline within the next few weeks and this is currently the only thing blocking me from submitting my app. Could someone please investigate on the backend and let me know what's causing this, or complete the enrollment manually if possible?

I'm happy to provide any additional information needed — Apple ID, screenshots, timestamps of attempts, etc.

Thank you for your help.
