## Basic Organization Information

* Edition information: YiDA currently offers four editions—Free plan, Basic edition, Professional edition, and Dedicated edition. Your organization's current YiDA edition is displayed here.
* Organization name: The name of the organization you are currently signed in to.
* Corp ID: A unique identifier assigned by DingTalk to each registered organization, used to identify and distinguish enterprise accounts and ensure data isolation and security.
* Corp Token: Also known as the Organization Credential, the Corp Token is a security token used to authenticate and authorize access to organization resources and services.
* Domain: The domain used by the organization in YiDA. Paid editions of YiDA include the right to change the second-level domain up to three times. The YiDA Free plan does not currently support second-level domain changes.

<Note>
