What Domains Can Wildcard-Domain Certificates Support?

You can purchase wildcard-domain certificates in SCM to protect a single domain name of the server and all its subdomains of the same level. Wildcard domains are supported by OV, OV Pro, and Geo Trust entry-level DV (Basic) certificates.

If you have multiple subdomain names at the same level, you do not need to purchase and install certificates for each subdomain name when using a wildcard-domain certificate.

• For wildcard-domain certificates, only those associated with root domain names support the domain names. For example:
• Once your digital certificate is issued, the associated domain cannot be changed.

To purchase a wildcard-domain certificate, you need to pay attention to the domain name matching rules. Only subdomain names of the same level can be matched. For details about the domain name levels, see Domain-related Concepts.

Table 1 provides matching examples.
