How Long Does an SSL Certificate Take Effect After Being Purchased?

After an SSL certificate is purchased, you need to apply for the certificate. The CA reviews the application submitted by the user and issues the certificate only after the application is approved.

A certificate takes effect immediately upon issuance.

An SSL certificate is valid for one year. Once an SSL certificate expires, it cannot be used.

If an additional domain name is added for a multi-domain certificate, the certificate validity period starts from the date when the certificate is issued for the first time.
