Erolling Apple Developer Hung at "We'll Be Back Soon"

For issues with developer program enrollment: nobody here can assist with this. We’re other users, and some here are third-party developers.

In general…

You will need a major payment card associated with the Apple ID. Don’t bother trying to use an Apple ID balance or gift cards to enroll.

You will also need an email-format Apple ID, and not an Apple ID that is a mobile telephone number.

If you are located in India, you must enroll via the Apple Developer app.

Paid program members can be individual developers, or can be certain legally-recognized organizations. The latter enrollment usually requires a DUNS number.

You will need to be in a country or region where Apple is active, and will need to be someone or some legal entity that Apple can legally do business with; not a denied person or denied entity.

Don’t be using a VPN, either.

If you want to keep things separate (as can be reasonable for many cases), creating a new Apple ID and enrolling that in the program, and using that (just) for Developer and App Store activities and such. You can enroll your own Apple ID (this works fine!), but that can get tangled with whatever personal info and purchases are already associated with your Apple ID. Apple has gotten better about allowing you to transfer one or more of your apps to other developers as needed, though.

If enrollment issues persist, contact Apple.
