Validation process
Before DigiCert can issue any type of certificate, the certificate order must go through a validation process.
For OV and EV TLS/SSL, Private SSL, Code Signing, and Document Signing certificate orders, the certificate’s validation process includes organization validation and verifying the organization contact. For certificates that are issued to a domain (TLS/SSL and some client certificates), the certificate order process includes domain validation.
To quicken the certificate issuance process, you'll want to submit your organizations and domains for pre-validation. Once you've completed pre-validation, future certificate issuance and renewals for those domains and organizations can be done almost immediately.
