Forbidden domain names

Unfortunately, we don't provide or issue SSL Certificates for domains that contain a brand, or subdomains of well-known hosting providers.

👉These certificates will be automatically canceled and the user will receive an email confirming this action.

We don't have a list of forbidden brand names, but the examples below occurred already in the past and won't work with ZeroSSL.

Brand names

  • amazon, aws
  • ebay
  • skype
  • microsoft
  • and so on ... 


  • *
  • *
  • *
  • and so on ...

Are you affected by this?

This is an example of an certificate that cannot be issued.
