Are AWS accounts available for new registrations again?

Actually, AWS accounts were never completely closed. It just seemed like that at times. If you faced a ban, it might have been a temporary glitch or policy enforcement.

If you're still having trouble, check out this article on account creation that could help: http://go.aws/create-account. If you need more assistance, opening a support case might be a good way to go!

Oh, you thought they were banning everyone? That might have been the case for a few months, but it's hard to say how long that really lasted. Have you tried registering again?

They usually shut down new registrations during the Christmas break, so you might want to try again in January.

No accounts are being opened unless you can demonstrate having an Azure tenant and a Google Cloud Platform organization. Seems like they’re strict about new sign-ups.
