I tried registering a domain name using AWS' Route 53, they wouldn't allow me to because "my billing information wasn't verified". I tried again after passing the verification and it still wouldn't let me for the same reason. I ended up registering it in Cloudflare (for less money, btw) and after setting up an EC2 instance for my prod. environment + email hosting, after checking my billing info, much to my surprise, the domain I tried to register appeared in the invoice.
Not only that, but they won't even allow me to send emails through my EC2 instance because they block IMAP port 25 by default, and when trying to request an unlock, they don't authorize it because "my account has either bad billing history (I'm guessing it's related to the registration???), has incurred in activities against ToS (haven't been banned ONCE) or I didn't describe the purpose of the unlocking request (I provided a long text describing each activity my team is planning to do with the email)"
