Starting today, public certificates issued from AWS Certificate Manager (ACM) have a maximum validity period of 198 days, compared to previous validity period of 395 days. With this change, ACM-issued public certificates will be compliant with new Certification Authority Browser (CA/Browser) Forum mandate that certificates be no longer than 200 days starting 15th March 2026.
No action is required from the customers to receive this change. All new and renewed public certificates will by default have a validity of 198 days. Existing certificates with 395 days validity continue to be valid and can be used until they renew or expire. All other certificate functionality remains in place. ACM will still continue to auto renew the certificates before expiry. The certificates are now renewed 45 days before expiry. Existing 398 day validity certificates will renew 60 days before expiry and will renew with 198 days validity period.
We have reduced the pricing for ACM’s exportable public certificates in line with the shorter validity period. 198-day exportable public certificate will now cost $7/Fully Qualified domain name (down from $15) and $79/ wildcard name (down from $149). Please refer to ACM’s pricing page for more details. For more information about ACM, visit the ACM documentation.
