  • The bucket name can only start with a letter or number, not a dot or hyphen and should not start with “xn-”
  • The bucket name should not end with “-s3alias” which is reserved for access point aliases.
  • Names shouldn’t be formatted as an ip address ie
  • Avoid using dots in the bucket name, unless you are intending to use it as a static website.
