Before a SSL certificate can be issued the issuer of the certificate performs an authorization to verify the purchaser of the certificate is who they claim they are. There are today 3 standard ways of authorization:

  • Domain validation
  • Organizational validation
  • Extended validation

From top to bottom the methods are more comprehensive and therefore also more expensive.

Domain validation - an email is sent to the email listed in the WHOIS information on the domain. Instructions in the mail must be followed.

Organizational validation  - includes domain validation as well as you will need to send in documents confirming your identity (for companies this means company certificate/documentation.

Extended validation - includes organizational validation as well as in some cases needing to sign documents (the owners of the company) with an attorney present.
