~/tools / AWS ARN Parser
AWS ARN Parser
Break an AWS ARN (Amazon Resource Name) down into its components: partition, service, region, account ID, and resource.
ARN strings like arn:aws:... in IAM policies and CloudFormation templates can be long and hard to parse at a glance. This breaks one down so you can immediately see which service, region, and account it points to.
# Use Cases
- Figuring out which region and account an ARN in an error log actually points to
- Quickly reading the components of an ARN listed in an IAM policy's Resource field
- Checking whether an ARN belongs to your own account in a multi-account setup
# Usage
- Paste the ARN you want to inspect into the input box.
- It's automatically broken down into partition, service, region, account ID, and resource.
- Partition
- aws
- Service
- iam
- Region
- (none — global service)
- Account ID
- 123456789012
- Resource
- role/MyServiceRole
# FAQ
- Is this an official AWS tool?
- No, this is an independent, unofficial parser and is not affiliated with Amazon Web Services. "AWS" is a trademark of Amazon.com, Inc. or its affiliates.
- Can the region or account ID be empty?
- Yes. Some global or bucket-scoped resources, like IAM roles and S3 buckets, legitimately have an empty region and/or account ID field.
