AWS ARN Parser
Parse an AWS ARN and break it down into partition, service, region, account ID, and resource.
Paste an AWS ARN below - this tool breaks it into its component parts and explains what each one means.
Use the AWS ARN Generator if you need to go the other direction - building an ARN from its components.
What Is an AWS ARN?
An Amazon Resource Name (ARN) uniquely identifies an AWS resource across all of AWS, in the format arn:partition:service:region:account-id:resource - used in IAM policies, CLI commands, and API calls to reference a specific resource.
Why Use This Tool?
ARN structure varies slightly by service (some omit the region or account ID, some use a colon vs. a slash before the resource part), which makes them easy to misread at a glance. This tool breaks any ARN into labeled parts.
How to Use It
- Paste an ARN, e.g.
arn:aws:s3:::my-bucketorarn:aws:iam::123456789012:role/MyRole. - Click Parse.
- Review the partition, service, region, account ID, and resource, each explained.
Limitations
This parses the general 6-part ARN structure common to most AWS services - a small number of services use further nested resource-type/resource-id conventions this tool surfaces as-is rather than further subdividing.
