Amazon Resource Names (ARNs) in GovCloud (US) Regions
Amazon Resource Names (ARNs) uniquely identify AWS resources. We require an ARN when you need to specify a resource unambiguously across all of AWS, such as in IAM policies, Amazon S3 bucket names, and API calls. In AWS GovCloud (US) Regions, ARNs have an identifier that is different from the one in other standard AWS Regions. For all other standard regions, ARNs begin with:
arn:aws
In the AWS GovCloud (US) Regions, ARNs begin with:
arn:aws-us-gov
If an ARN requires you to specify a Region:
-
For the AWS GovCloud (US-West) Region, use
us-gov-west-1. -
For AWS GovCloud (US-East) Region, use
us-gov-east-1.
For additional information about ARNs, see Amazon Resource Names (ARNs) in the AWS General Reference.
