This topic describes what an Enterprise Account is and the API capabilities that Enterprise Account provides. ## What is an Enterprise Account An Enterprise Account is an account that an organization can manage. The organization manages the entire account lifecycle, including create, modify, disable, and enable operations. For more details, see [DingTalk User Guide - Enterprise Account introduction](https://docs.dingtalk.io/i/p/Y7kmbokZp3pgGLq2/docs/Y7kmbEj6djBVjXLq?dontjump=true%23%23). The following two types are currently available: * single sign-on account: Sign in to DingTalk using the existing account system within the organization. Account management is performed outside DingTalk. * DingTalk Enterprise Account: An Enterprise Account created and managed within DingTalk. ## How to enable Enterprise Account This feature is currently in gray release. If your organization has not enabled it, [submit a trial application](https://www.aliwork.com/o/dingtalk-jjfa?spm=a213l2.15044028.1543252304.1.6a2e5632YehstI\&acm=lb-zebra-694702-8604571.1003.4.8185952\&scm=1003.4.lb-zebra-694702-8604571.OTHER_15916559412151_8185952#/?channel=%E4%B8%93%E5%B1%9E%E9%92%89%E9%92%89-%E5%92%A8%E8%AF%A2%E4%B8%93%E5%AE%B6-PC) first. ## API capabilities provided by Enterprise Account Enterprise Account provides a rich set of open API capabilities.

The Organization Code is the unique identifier of an organization that uses Enterprise Account. When an organization enables the Enterprise Account feature, DingTalk assigns a random 8-digit Organization Code by default. Contact your account Admin to view it at [DingTalk Admin Console](https://oa.dingtalk.io/) > **Settings** > **Organization Code**. The organization Admin can also apply for a more personalized code to make it easier for users in the organization to remember and use.
