Region codes are used throughout AWS - in ARNs, CLI commands (--region), and console URLs - so having the exact code matters.

What Is an AWS Region?

An AWS Region is a separate geographic area (like us-east-1 for Northern Virginia, or eu-west-1 for Ireland) containing multiple isolated data centers (Availability Zones) - most AWS resources are created within a specific region.

Why Use This Tool?

Region codes aren't always intuitive (us-east-1 is Northern Virginia, not a generically 'first' region), and it's easy to reference the wrong one in a CLI command or Terraform config. This tool makes it quick to look up the correct code for a location.

How to Use It

Type a region name (e.g. "Ireland") or a partial code (e.g. "us-east").
Review matching regions with their full code and location.

Limitations

AWS occasionally launches new regions - this reference reflects widely-used regions at the time of writing; always confirm against AWS's own region list for the most current availability.

Frequently Asked Questions

Pick one close to your users for lower latency, check that the services you need are available there, and consider data residency rules and price differences.

Asia Pacific (Mumbai) is ap-south-1 and Asia Pacific (Hyderabad) is ap-south-2.

No. Newer services often launch in a few regions first. Check the AWS Regional Services list before choosing a region.
