In SCM, options for Domain Type can be Single domain, Multiple domains, or Wildcard.

**Table 1** Domain Type
Parameter	Description
Single domain	Only one common domain name can be associated. If you have only one domain name, select Single domain.
Multiple domains	Multiple domains can be added to a certificate. Multiple single domains can be set for domains. For example, you can use one multi-domain certificate to protect domains example.com, example.cn, and test.com. You need to configure the domain quantity based on the number of domains you need to protect with a single multi-domain certificate. The number of domain names ranges from 2 to 250. A maximum of 250 domain names can be protected with a certificate. If you have multiple domain names, select Multiple domains. Purchase domain names of the required quantity on the purchase page.
Wildcard domain	Only one wildcard domain name can be associated. If all of your domain names are at the same level, select Wildcard.

Before you purchase a wildcard-domain certificate, pay attention to the domain name matching rules. Table 2 are some examples.

**Table 2** Examples of wildcard-domain matching rules
Domain name	Matched Domain Name	Unmatched Domain Name

NOTICE:

For wildcard-domain certificates, only those associated with root domain names support the domain names. For example:
If the www subdomain is associated with a certificate, the certificate also protects the root domain. For example:
Once your digital certificate is issued, the associated domain cannot be changed.

Table 3 is given here for your reference.

**Table 3** Domain type selection examples
