AWS Region Lookup
Look up AWS region codes, names, and locations - search by code or name.
Search by region code or name to quickly find the AWS region you're looking for.
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.
