AWS have a ridiculously unreasonable account verification process. Having sent everything they ask for I just keep getting the same big list of criteria without any more feedback on exactly what their issue is.

I hope your not relying on big tech / cloud providers who will suspend your account without warning and have a self hosted alternative.

Why will a financial institution accept a drivers licence, letter addressed to me and bank statements but AWS wont?

I'm so annoyed that I don't care if they don't let me in. It shows you exactly what AWS is really like and that they only serve huge international corporations.
