Organizational Unit (OU) Field to be Deprecated by

Important Announcement:

  • The Organizational Unit (OU) Field within an SSL/TLS (website) Certificate, will be deprecated effective September 1, 2022, at the request of the CA/Browser Forum.  
  • will discontinue the field effective August 1, 2022, in order for customers to get accustomed to the change.

Why Is This Occurring?

The Certificate Authority/Browser Forum (CA/B) has been investigating ways to further strengthen the validation of an SSL/TLS (website) Certificate. 
  • While other methods were not adequate, attention was focused on discontinuing the OU Field. 
  • The Field is ambiguous as it is an internal label with little text standardization. 
  • The field cannot be validated effectively and could be misused.
  • adheres to the operational standards ratified by the Certificate Authority/Browser (CA/B) Forum. 
  • As with all the certificates issued by, it is in the best interest of SSL’s customers to ensure compliance.
  • As with all products, our adherence to standards, quality, and customer satisfaction remains our top priority. 


Moving Forward: 

  • Customers are urged to review their internal Certificate Management practices, ensuring no dependency on the field moving forward.
  • Certificates issued prior to August 1, 2022, will remain valid. 
  • Customers who have known dependencies on the OU field and cannot resolve it are urged to reprocess and reissue before July 31, 2022, to ensure functionality. 
  • Effective August 1, 2022, will no longer present the field for use. 

Information is provided:

  • To alert our customers to the change. 
  • Provide time to redesign any processes currently contingent on the field.
