[ aws . route53domains ]



This operation checks the availability of one domain name. Note that if the availability status of a domain is pending, you must submit another request to determine the availability of the domain name.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.


--domain-name <value>
[--idn-lang-code <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]


--domain-name (string)

The name of the domain that you want to get availability for. The top-level domain (TLD), such as .com, must be a TLD that Route 53 supports. For a list of supported TLDs, see Domains that You Can Register with Amazon Route 53 in the Amazon Route 53 Developer Guide .

The domain name can contain only the following characters:

  • Letters a through z. Domain names are not case sensitive.

  • Numbers 0 through 9.

  • Hyphen (-). You can’t specify a hyphen at the beginning or end of a label.

  • Period (.) to separate the labels in the name, such as the . in example.com .

Internationalized domain names are not supported for some top-level domains. To determine whether the TLD that you want to use supports internationalized domain names, see Domains that You Can Register with Amazon Route 53 . For more information, see Formatting Internationalized Domain Names .

--idn-lang-code (string)

Reserved for future use.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


To determine whether you can register a domain name with Route 53

The following check-domain-availability command returns information about whether the domain name example.com is available to be registered using Route 53.

This command runs only in the us-east-1 Region. If your default region is set to us-east-1, you can omit the region parameter.

aws route53domains check-domain-availability \
    --region us-east-1 \
    --domain-name example.com


    "Availability": "UNAVAILABLE"

Route 53 supports a large number of top-level domains (TLDs), such as .com and .jp, but we don’t support all available TLDs. If you check the availability of a domain and Route 53 doesn’t support the TLD, check-domain-availability returns the following message.

An error occurred (UnsupportedTLD) when calling the CheckDomainAvailability operation: <top-level domain> tld is not supported.

For a list of the TLDs that you can use when registering a domain with Route 53, see Domains That You Can Register with Amazon Route 53 in the Amazon Route 53 Developer Guide. For more information about registering domains with Amazon Route 53, see Registering a New Domain in the Amazon Route 53 Developer Guide.

Valid values:


The domain name is available.


The domain name is reserved under specific conditions.

The TLD registry didn’t reply with a definitive answer about whether the domain name is available. Route 53 can return this response for a variety of reasons, for example, the registry is performing maintenance. Try again later.


The TLD registry didn’t return a response in the expected amount of time. When the response is delayed, it usually takes just a few extra seconds. You can resubmit the request immediately.
