DigiCert TLS/SSL Certificates Shortened Validity to 199 Days

Starting February 24 2026, TLS/SSL certificates issued through DigiCert CertCentral will have a maximum validity of 199 days (down from 397 days), including EU Qualified Website Authentication Certificate (QWAC) and QWAC PSD2 certificates.

This change to shorter validity is an industry-wide requirement mandated by new CA/Browser Forum baseline requirements. The goal is to improve security by limiting the impact of compromised keys and enabling faster cryptographic updates as threats and standards evolve.

While shorter lifetimes may require adjustments, they also reduce risk and help keep your environments more resilient over time. DigiCert provides automation and tooling to make renewals as seamless as possible. Please contact us for more information on automation for your SSL re-issuance.

Below is a brief summary of the impact this change will have to your certificate environment.

Impact to certificates:

• You can continue to order TLS/SSL certificates with validity longer than 199 days until February 24, 2026.
• Any certificates issued on or after February 24 will be limited to a maximum of 199 days, even if the order requested a longer validity period.
• Pending requests issued on or after February 24 will be truncated to 199-day validity regardless of the validity period detailed in the order request.
• If you need certificates with longer validity, we recommend placing your orders well before February 24, 2026 and making sure your domain and organization validations are up to date to avoid delays.
• Existing certificates are not affected. Certificates issued before February 24 will remain valid until their original expiration date.
• However, if a certificate is reissued on or after February 24, it will be limited to 199 days, even if the original certificate was valid for longer.

Impact to organization and domain validations:

• On February 24, OV organization validation reuse periods will be shortened from 825 days to 397 days.
• On February 24, domain validation reuse periods will be shortened from 397 days to 199 days.
