By default, you can apply for wildcard certificates, single-domain certificates, and multi-domain certificates in the Certificate Management Service console. You can bind a multi-domain certificate to up to five single domain names. You can apply for multi-domain certificates and hybrid certificates of the organization validated (OV) or extended validation (EV) type by combining multiple certificate instances. You cannot apply for multi-domain certificates or hybrid certificates of the domain validated (DV) type.

Combine certificate instances

You can combine multiple wildcard certificate instances and use the combined certificate instances to apply for certificates. You can also combine multiple single-domain certificate instances and wildcard certificate instances and use the combined certificate instances to apply for certificates. For example, you can combine multiple wildcard certificate instances and use the combined certificate instance to apply for a multi-domain certificate. You can also combine wildcard certificate instances and single-domain certificate instances, and use the combined certificate instance to apply for a hybrid certificate.

Make sure that the following conditions are met before you combine certificate instances:
  • OV or EV certificate instances of the same brand are purchased, and the certificate instances have a validity period of one year.
  • The certificate instances are in the Pending Application or Validation Failed state.
