Flex certificates

DigiCert offers TLS certificates that support different types of domain configurations. Some can be ordered as single-domain or multi-domain certificates, while others can be ordered with any combination of fully qualified domain names (FQDNs) and wildcard domains.

OV TLS flex certificate combinations

EV TLS flex certificate combinations

  • Single domain

  • Multiple domains

  • Single wildcard domain

  • Multiple wildcard domains

  • Combination of domains and wildcard domains

  • Single domain

  • Multiple domains

This allows you to order the certificates you want and add additional subject alternative names (SANs) during your certificates' lifetime without changing products. These certificates do not have dedicated multi-domain or wildcard versions. Instead, you add those as you configure the base certificate.

All DigiCert SSL certificates allow you to cover both the base domain and the www subdomain at no added cost. With flex certificates, you must include both versions in your request, because they will not be added automatically. This also applies to Wildcards ( available for free with * and multi-level subdomains ( available for free with If you are using the API, read how to configure your API request to include both versions of the domain for free.

The common name and SANs listed in your CSR are ignored. You must include all domains you want covered in your CertCentral or API request.


The total price of a flex certificate is calculated by the base price/value of the certificate, plus the total number of SANs:

Certificate base price/value + FQDN total(FQDN SAN price * Number of FQDN SANs) + Wildcard total(Wildcard SAN price * Number of wildcard SANs)*

*When ordering server licenses, multiply the above total by the total number of licenses.

When ordering through CertCentral, the price will update with the certificate's configuration. You can see the current price in the Transaction summary on the right-hand side of the Request page, or by using the order-pricing API.
