CheckDomainAvailability - Amazon Route 53
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

CheckDomainAvailability

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.

Request Syntax

{ "DomainName": "string", "IdnLangCode": "string" }

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

DomainName

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.

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

Availability

Whether the domain name is available for registering.

Note

You can register only domains designated as AVAILABLE.

Valid values:

AVAILABLE

The domain name is available.

AVAILABLE_RESERVED

The domain name is reserved under specific conditions.

AVAILABLE_PREORDER

The domain name is available and can be preordered.

DONT_KNOW

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.

INVALID_NAME_FOR_TLD

The TLD isn't valid. For example, it can contain characters that aren't allowed.

PENDING

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.

RESERVED

The domain name has been reserved for another person or organization.

UNAVAILABLE

The domain name is not available.

UNAVAILABLE_PREMIUM

The domain name is not available.

UNAVAILABLE_RESTRICTED

The domain name is forbidden.

Errors

For information about the errors that are common to all actions, see Common Errors.

InvalidInput

The requested item is not acceptable. For example, for APIs that accept a domain name, the request might specify a domain name that doesn't belong to the account that submitted the request. For AcceptDomainTransferFromAnotherAwsAccount, the password might be invalid.

HTTP Status Code: 400

UnsupportedTLD

Amazon Route 53 does not support this top-level domain (TLD).
