Data Mask & Seed is available for customer production use, including Government Cloud, in all Salesforce regions. Salesforce automatically redirects users to their closest Salesforce region.

**When:** This Data Mask & Seed feature is generally available during October 2026.

**Who:** To access and work with Data Mask & Seed, assign users the following Permission Set License and Permission Set. Make sure to assign the Permission Set License before assigning the Permission Set:
