Container for the parameters to the CreateOrganizationalUnit operation. Creates an organizational unit (OU) within a root or parent OU. An OU is a container for accounts that enables you to organize your accounts to apply policies according to your business requirements. The number of levels deep that you can nest OUs is dependent upon the policy types enabled for that root. For service control policies, the limit is five.

For more information about OUs, see Managing Organizational Units in the AWS Organizations User Guide.

This operation can be called only from the organization's master account.

public class CreateOrganizationalUnitRequest : AmazonOrganizationsRequest

The CreateOrganizationalUnitRequest type exposes the following members



Public Property Name System.String

Gets and sets the property Name.

The friendly name to assign to the new OU.

Public Property ParentId System.String

Gets and sets the property ParentId.

The unique identifier (ID) of the parent root or OU in which you want to create the new OU.

The regex pattern for a parent ID string requires one of the following:

  • Root: a string that begins with "r-" followed by from 4 to 32 lower-case letters or digits.

  • Organizational unit (OU): a string that begins with "ou-" followed by from 4 to 32 lower-case letters or digits (the ID of the root that the OU is in) followed by a second "-" dash and from 8 to 32 additional lower-case letters or digits.


The following example shows how to create an OU that is named AccountingOU. The new OU is directly under the root.:

To create a new organization unit

var response = client.CreateOrganizationalUnit(new CreateOrganizationalUnitRequest 
    Name = "AccountingOU",
    ParentId = "r-examplerootid111"

OrganizationalUnit organizationalUnit = response.OrganizationalUnit;
