How Long Is an SSL Certificate Valid?

The validity period of an SSL certificate issued before March 15, 2026 is one year. That is, the certificate is valid within one year after approval. The validity period of an SSL certificate issued after March 15, 2026 is 200 days. After the validity period expires, the certificate cannot be used.

You can renew an SSL certificate before it expires. For details, see Renewing an SSL Certificate.

If you have not enabled auto-renewal, manually renew the certificate or purchase another one 3 to 10 working days before it expires. If you have enabled auto-renewal, check the SMS notifications, and finish required verification 3 to 10 working days before it expires to ensure that the certificate is valid before the CA validates your verification and issues new certificate.

When Does the Certificate Validity Period Start?

A certificate takes effect upon issuance. The certificate issuance time refers to the time when the certificate is officially issued by the CA.

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.

When Will a Notification Be Sent Before a Certificate Expires?

SCM will notify you of certificate expiration 30 days before the certificate expires.

For certificates purchased through SCM, the system automatically notifies you via email and SMS one month, one week, three days, and one day before expiration, as well as on the day the certificate actually expires.
For an SSL certificate you upload to SCM, if you still need to use it, you need to upload a new one before it expires. For details, see Uploading an External SSL Certificate.

You can renew only paid SSL certificates you have purchased in Huawei Cloud SCM before they are about to expire. For details, see Renewing an SSL Certificate.
