Individual/Sole Proprietor enrollment — persistent "Unknown error occurred"

Hello,

I've been trying to enroll in the Apple Developer Program as an Individual/Sole Proprietor for several days now, and I keep hitting the same error after submitting my personal information:

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

What I've already checked and tried:

-Tried multiple browsers (Chrome, Safari, Edge) -Cleared cache and cookies, tried incognito/private mode -No VPN active -Two-factor authentication is enabled and working -My Apple ID region is set to France -Tried both the Developer app flow and developer.apple.com/enroll (web) directly

Additional context that may be relevant: I'm based in La Réunion (French overseas department/DOM), and my trusted phone number for 2FA is a local +262 number. La Réunion isn't listed separately as an App Store region (it falls under France), so my Apple ID country/region is set to France — but I wonder if there might be a mismatch check happening somewhere between the phone number's country code and the Apple ID region that's causing this.

This is blocking my app's TestFlight/App Store release, so any guidance — from Apple staff or from other developers who've faced this and found a fix — would be really appreciated.

Thank you!
