Individual enrollment: “Enrollment is not available for this account” on one Apple Account only

Hi,

I’m trying to enroll in the Apple Developer Program as an individual (Türkiye) and I’m stuck.

With my main Apple Account (region: Türkiye), enrollment fails with “Enrollment is not available for this account”, and the identity status page says “Your enrollment could not be completed.”

What I’ve checked on this account:
• Name matches my government ID
• Date of birth is correct (over 18)
• Region is Türkiye
• Two-factor authentication is on
• Not part of a Family Sharing group

As a test, I signed in with a second Apple Account of mine (same person, same identity) and it went straight to the “Confirm your personal information” form. So the restriction seems to be specific to my main account, not to my identity.

I opened a support case (103002229051) on October 20, but I’ve only received the automatic confirmation so far, and phone support shows “due to high demand” when I try during business hours.

I have two apps ready for TestFlight and would really like to enroll with my main account. Could someone from Apple look into this, or point me to the right team?

Thank you!
