EnableRegion - AWS Account Management


Enables (opts-in) a particular Region for an account.

Request Syntax

POST /enableRegion HTTP/1.1 Content-type: application/json { "AccountId": "string", "RegionName": "string" }

URI Request Parameters

The request does not use any URI parameters.

Request Body

The request accepts the following data in JSON format.


Specifies the 12-digit account ID number of the AWS account that you want to access or modify with this operation. If you don't specify this parameter, it defaults to the AWS account of the identity used to call the operation. To use this parameter, the caller must be an identity in the organization's management account or a delegated administrator account. The specified account ID must also be a member account in the same organization. The organization must have all features enabled, and the organization must have trusted access enabled for the Account Management service, and optionally a delegated admin account assigned.


The management account can't specify its own AccountId. It must call the operation in standalone context by not including the AccountId parameter.

To call this operation on an account that is not a member of an organization, don't specify this parameter. Instead, call the operation using an identity belonging to the account whose contacts you wish to retrieve or modify.

Type: String

Pattern: ^\d{12}$

Required: No


Specifies the Region-code for a given Region name (for example, af-south-1). When you enable a Region, AWS performs actions to prepare your account in that Region, such as distributing your IAM resources to the Region. This process takes a few minutes for most accounts, but it can take several hours. You cannot use the Region until this process is complete. Furthermore, you cannot disable the Region until the enabling process is fully completed.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 50.

Required: Yes

Response Syntax

HTTP/1.1 200

Response Elements

If the action is successful, the service sends back an HTTP 200 response with an empty HTTP body.
