Hello ​@alanfeng009,

Thank you for reaching out, and a warm welcome to the Docusign Community! We are absolutely delighted to have you here and can't wait to share our knowledge with you.

I understand you would like to test the Identity Verification feature in your Sandbox account, but you cannot use it. I sincerely apologize.

Per the community guidelines (https://community.docusign.com/site/terms) the Account Admin will need to contact Support for Feature enablement request. Please see below the process on how to open a Support case:

• With Production environment account: To open a support case in the Docusign Support Center, go to the "Get Support" section and select "Open a Support Case.” Log in using your Docusign credentials and select a case subject. If you have multiple Docusign accounts, choose the appropriate account to continue. Open a case in the Docusign Support Center. 
• No Production account: submit a case without logging into an account by using the “I can’t access my account” option at the bottom of the page and providing complete details of the issue in the Case description. Link: Get Support

Let us know if you need further assistance with this. Thank you!

Best regards,

Melanie | Docusign Community Moderator
