Types of SSL Certificates

SSL certificates differ in validation level and hostname coverage. Compare both dimensions before purchasing; a certificate can have the right validation level but still fail to cover the required hostnames.

Validation Types

Domain Validation (DV)
Organization Validation (OV)
Extended Validation (EV)

Coverage Types

Single-domain certificates
Wildcard certificates
Multi-domain certificates

How to Decide

List the exact domains and subdomains.
Choose the required identity-validation level.
Confirm server and platform compatibility.
Check renewal and reissue procedures.

Frequently Asked Questions

How do I know the change worked?

Check the current status in your NiceNIC account, then test the service that depends on the certificate type. Do not rely only on the absence of an error message.

When should I contact NiceNIC Support?

Submit a ticket when the required control is unavailable, the status remains pending after the checks in this guide, or the issue depends on an account-specific order or registry decision.
