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-bucket or arn: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.
