Product Validity Periods

What is the maximum validity for SSL Certificates?

Effective March 15, 2026, the maximum validity for all newly issued or reissued publicly trusted SSL/TLS orders will be 200 days. Due to changes in Apple and Google Root Store Policies, as of March 15, 2026, newly issued SSL/TLS Certificates with a validity period greater than 200 days are prohibited by policy and will not be trusted. Therefore, if you renew or purchase a certificate before March 15, 2026, you can still get the current maximum validity of 398 days. After that date, new certificates will follow the shorter lifespans set by the CA/B Forum’s timeline, starting with a 200-day maximum. To know more about this change, please refer to this blog.  

What is the maximum validity for Code Signing Certificates?

Starting March 1, 2026, the maximum validity period for Code Signing Certificates will be reduced from 39 Months to 460 days. All current Code Signing Certificates will remain valid until their expiration date. From 26 December 2025, GlobalSign will stop issuing 2-Year and 3-Year Code Signing Certificates. We will continue issuing with 1-Year (366 days) Code Signing Certificates. All new Code Signing Certificates issued or renewed after 24 February 2026, will be subjected to the new validity changes.
