What is an extended validation (EV) multi-domain SSL certificate?

Overview
Extended validation multi-domain SSL certificates allow a domain owner to assign multiple domains and sub-domains to a single SSL certificate. They differ from standard multi-domain SSL certificates in that they allow the inclusion of multiple fully qualified domain names (FQDN).

Attention

Apple browsers (Mojave, iOS) no longer support the visual cue associated with EV SSL certificates, which is the legal identity appearing to the left of the web address.. Chrome will likewise discontinue on September 10, 2019. Firefox will do the same on October 22, 2019. As a result, we recommend considering an alternative type. Contact our sales team for assistance.

Definition

EV multi-domain certificates are also known as a Subject Alternative Name (SAN) certificate. They are considered special due to the owner’s ability to validate multiple domains and subdomains with a single SSL certificate.  

  • www.example.com
  • example.com
  • blog.example.co.net
  • example.es 

Or multiple domain names, such as

  • www.example.com
  • example.co.net  
  • computing-ideas.com

An EV multi-domain name provides the ability to include multiple fully qualified domain names (FQDN) within the same certificate. However, EV multi-domain certificates will only support the specific FQDN entered into the certificate. In most cases, EV multi-domain certificates will support up to 100 FQDNs in one certificate. Only one unique IP address is required per domain name and one can add domain names for a relatively low cost. This gives a business an affordable means of attaching multiple trading names to one certificate.
