How can I find which Availability Zones I can use in my account?

Last updated: 2022-11-07

I want to use an Availability Zone (AZ), but it's unavailable for my account. How can I find which AZs I can use in my account?

Short description

As AZs grow, the ability for AWS to expand them can become constrained. As a result, you might notice the following:

  • Your account has fewer available AZs than what's publicly listed.
  • One of your accounts has a different number of available AZs in a Region than another account.

Resolution

To find which AZs you can use to launch resources in any of your accounts, do the following:

  1. Open the Amazon Elastic Cloud Compute (Amazon EC2) console.
  2. From the navigation bar, view the options in the Region selector.
  3. On the navigation pane, choose EC2 Dashboard.
  4. In the Service Health section, view the list of AZs under Availability Zone Status.

Also, you can run the following command in the AWS Command Line Interface (AWS CLI) to generate a list of AZs in your account.

Note: If you receive errors when running AWS Command Line Interface (AWS CLI) commands, make sure you confirm that you’re running a recent version of the AWS CLI.

Note: Be sure to replace region-name with your Region's name. For example, ap-northeast-1.

aws ec2 describe-availability-zones --region region-name
