How it works

Colon separators split the stable ARN envelope, then service-specific resource delimiters expose the remaining name. Wildcards remain literal policy characters rather than being expanded.

  • The six envelope fields are stable across AWS services.
  • Resource syntax varies by service.

Worked example

Parse IAM User ARN
Extract components from an AWS IAM user ARN
Input
											arn:aws:iam::123456789012:user/johndoe
Output
												Arn: arn:aws:iam::123456789012:user/johndoe
Partition: aws
Service: iam
Region: (global)
Account ID: 123456789012
Resource: user/johndoe
Resource type: user
Resource ID: johndoe

When to use this

IAM reviews, deployment configs, and security inventory parse ARNs.

Edge cases

  • Global services can have empty region or account fields.
  • Resource text can contain colons or slashes.
  • A wildcard ARN is a policy pattern, not one resource.
