AWS ARN Parser
Parse AWS ARN partition, service, region, account, resource type, ID, and qualifier
Parses ARN structure and common service constraints locally. It does not call AWS APIs or verify resource existence or permissions.
Partition, service, region, account, and resource will appear here.
About this tool
AWS ARN Parser separates an Amazon Resource Name into partition, service, region, account ID, raw resource, resource type, resource identifier, separator, and optional qualifier. It checks the generic six-part structure and reports warnings for account length, partition-region mismatches, and common S3, IAM, Lambda, EC2, CloudWatch Logs, KMS, Secrets Manager, DynamoDB, SNS, SQS, and API Gateway conventions. Service formats evolve and many services have special grammar, so a warning is a review aid rather than an authoritative AWS API validation. No credentials are requested and no resource lookup is performed.
Scenario Recipes
Review an IAM policy resource reference
Goal: Catch an account, region, or resource-type typo before policy deployment
- Paste the Resource ARN from the policy statement.
- Compare partition, service, account, region, resource type, and qualifier with the deployment target.
- Resolve warnings against current service documentation, then test the policy through the approved AWS review process.
Result: A field-by-field ARN review without requiring cloud credentials.
Frequently Asked Questions
What are the main ARN fields?
An ARN contains arn, partition, service, region, account ID, and a service-specific resource section.
Why can the resource contain more colons?
The first five colons delimit generic fields; everything after them belongs to service-specific resource grammar.
Does every ARN require region and account ID?
No. Global services and resources such as common S3 bucket ARNs can leave one or both fields empty.
Can the parser verify that a resource exists?
No. It performs local structural checks and never calls AWS or requests credentials.
Are warnings definitive validation errors?
No. They flag common conventions; consult current service documentation for specialized or newly introduced ARN forms.
Is the ARN uploaded?
No. Splitting, field extraction, JSON generation, and checks happen locally.
