Displays Availability Zones that are currently available to the account. The results include zones only for the Region you're currently using.
![]() | Note |
|---|---|
Availability Zones are not the same across accounts. The Availability Zone us-east-1a for account A is not necessarily the same as us-east-1a for account B. Zone assignments are mapped independently for each account. |
You can filter the results to return information only about zones that match criteria you specify. For example, you could filter the results to return only the zones whose state is available. You can specify multiple filters (e.g., the zone is in a particular Region, and the state is available). The result includes information for a particular zone only if it matches all your filters. If there's no match, no special message is returned; the response is simply empty.
You can use wildcards with the filter values: * matches zero or more characters, and ? matches exactly one character. You can escape special characters using a backslash before the character. For example, a value of \*amazon\?\\ searches for the literal string *amazon?\.
The following table shows the available filters.
