AWS ARN Parser

Paste any AWS Amazon Resource Name (ARN) to see its partition, service, region, account ID, resource type, and resource ID at a glance. Malformed ARNs are flagged and, where possible, a matching AWS console URL is generated.

Tool-Zusammenfassung

Dieses Tool nimmt strukturierte Eingaben entgegen und liefert deterministische Ausgaben im Browser, ohne Server-Upload.

Tool-Name
AWS ARN Parser
Eingabe-Intention
Liefere Quellinhalte zum Umwandeln, Validieren oder Analysieren.
Ausgabe-Intention
Erhalte normalisierte Ausgabe, geeignet zum Kopieren, Wiederverwenden oder Debuggen.
Beispiel-Eingabe
arn:aws:lambda:us-east-1:123456789012:function:processOrders:PROD
Beispiel-Ausgabe
service=lambda · region=us-east-1 · function "processOrders:PROD"

Local processing / privacy notice

  • Inputs are processed in your browser session.
  • We do not send raw input/output values to our analytics endpoint.
  • Use reset/clear actions when working with confidential data.
The ARN is parsed entirely in your browser.
Examples:
Partition
aws
Service
lambda
Region
us-east-1
Account ID
123456789012
Resource type (colon)
function
Resource ID
processOrders:PROD
Console
https://console.aws.amazon.com/lambda/home?region=us-east-1#/functions/processOrders%3APROD
ARN structure reference
arn:<partition>:<service>:<region>:<account-id>:<resource>
                                            └─ resource-type (: or /) + resource-id

partition is usually aws, but may be aws-cn or aws-us-gov. Services like s3, iam, and cloudfront are global and omit region / account.

Tool-Einführung

Paste any AWS Amazon Resource Name (ARN) to see its partition, service, region, account ID, resource type, and resource ID at a glance. Malformed ARNs are flagged and, where possible, a matching AWS console URL is generated.

Tool-Überblick

Every addressable AWS resource has an ARN following the format arn:partition:service:region:account-id:resource. Services use subtle variations: S3 object ARNs skip region and account, IAM uses a slash delimiter on the resource segment, and Lambda packs the function name plus optional version after a colon. Getting these segments right matters for IAM policies, CLI commands, and CloudFormation references — this tool gives you a one-shot breakdown without having to remember service-specific quirks.

Anwendungsfälle

  • Decode an ARN you see in a CloudTrail log, alarm, or IAM policy
  • Verify an ARN is well-formed before pasting it into a CloudFormation template
  • Copy the service, region, or account ID out of a long ARN
  • Open the matching AWS console page for the resource

Eingabe-Intention

FAQ

What is an AWS ARN?+
An Amazon Resource Name uniquely identifies an AWS resource. The format is arn:<partition>:<service>:<region>:<account-id>:<resource>, where the resource portion varies by service.
Why is the region or account empty?+
Some services (IAM, S3, CloudFront, Route 53, Organizations) are global or their ARN format intentionally omits those segments.
What are partitions?+
AWS has multiple isolated partitions: aws (commercial), aws-cn (China), aws-us-gov (GovCloud), and aws-iso / aws-iso-b (intelligence community). ARNs across partitions are distinct even if the resource name matches.
Is my ARN sent to a server?+
No. Parsing happens entirely in your browser.
