Manage all your requested SMS signatures in the Alibaba Cloud Short Message Service console-Short Message Service(SMS)-阿里云帮助中心

Manage signatures

In the Short Message Service console, go to the Go China > Signatures page to view all signatures for your account. You can determine the availability of a signature based on its Signature State. To view change details and review history for new and modified signatures, go to the Review Records tab. The Review Records page displays the signature name, change type, ticket ID, signature source, associated qualifications, review status, submission time, and last update time. You can use the ticket ID to track the review progress. This feature is available for signatures in all statuses.

Signature status

The carrier filing status indicates the outcome of your signature's real-name filing with carriers. Before you send SMS messages, we recommend that you monitor the carrier filing status and keep it at "Filing Successful" to ensure successful delivery.

Alibaba Cloud determines the signature status based on a comprehensive assessment of factors including the review status, carrier filing status, and message sending activity. We recommend that you monitor the signature status and maintain its status as Available-Normal to prevent message delivery failures.

Signature status	Description
Available - Normal	The signature is approved and poses no identifiable risks associated with its real-name information, filing result, or sending history. The signature is ready for use.
Available - Abnormal	The signature has been approved, but the platform has identified potential risks that may affect its current or future use. These risks can be related to the signature itself, its real-name information, filing result, or sending history. You can hover over Available-Exception to view details about the issue and suggested actions.
Unavailable	The signature is unusable because it was previously rejected, disabled, or frozen. Consequently, related operations and permissions are restricted. Disabled: The platform has disabled the signature due to illegal or non-compliant behavior, prohibiting its use for template applications or message sending. Frozen: The signature is frozen by the platform or by you. A signature is automatically frozen if it has not been used for 6 months. A frozen signature cannot be used for template applications or message sending. A non-compliant signature (one that does not comply with carrier specifications) does not directly trigger freezing. Freezing occurs only when a signature has not been used to send messages for 6 consecutive months. A non-compliant signature shows the Available - Abnormal status, which affects only the sending success rate. Messages can still be sent with the signature, but the delivery rate is not guaranteed. If a signature is not used to send any messages for 180 days, the platform automatically freezes it, and its status changes to Unavailable. To prevent a signature from being frozen, you can send a test message from the Quick Start & Delivery Test page in the console to keep it active. If a signature is already frozen, you can click Unfreeze in the Actions column or submit an update by clicking Edit Signature. The signature is automatically unfrozen after the update is approved.

What is the logic behind the "Available - Normal" and "Available - Abnormal" statuses?

Carrier filing status

Carrier filing status	Description
Filing	The filing request has been submitted to the carrier and is awaiting a result.
Not Filed	A filing request has not yet been submitted to the carrier.
Filing Failed	The carrier filing was rejected.
Filed and Pending Verification	The carrier has reported that the filing is complete, but you must send a test message to verify the result. For verification steps, see One-Click Test.
Filing Expired	The previous filing result has expired because the signature has not been used for over 6 months.
Filing Successful	Filing is complete and test messages were sent successfully. You can now send messages normally.

Signature details

On the Signature Management tab, click a Signature to view its details. You can view the latest approved information for the signature, such as Basic Information, real-name filing information, associated qualifications, letter of authorization information (if any), and Other Attachments.

Signature actions

The available operations for a signature depend on its status. The actual options are displayed in the Actions column of the console.

Signature status	Actions	Description
Unavailable	Review and Change History	View the signature's change history and review status on the Review Records tab.
	Filing Records	Displays a dialog box with the signature's filing history and results. Check the latest filing result and proceed as described in Real-name registration and filing of signatures.
	Clone	Clones the current signature. The system automatically populates the signature parameters. You can modify the information and then click Submit to resubmit it for review.
	Freeze	Freezes the signature, making it unavailable (you cannot send messages, apply for templates, file with carriers, and so on). To unfreeze it later, you must ensure all signature information is compliant and accurate.
	Unfreeze	If you need to reactivate a frozen signature, you can manually click Unfreeze. You can also click Edit Signature and submit an update, which unfreezes the signature upon approval.
	Delete	Deletes the signature. This action cannot be undone. Proceed with caution. You cannot delete a signature if it has a pending change request (in Pending Review or Under Review status).
Available - Normal Available - Abnormal	Review and Change History	View the signature's change history and review status on the Review and Change History tab.
	Edit Associated Qualifications	Redirects you to the Modify Qualification page. Modify the qualification information as prompted on the page, and then click Submit to submit the qualification for review.
	Edit Signature	Redirects you to the Modify Signature page. You can change the source type or update the associated qualifications by linking to a different approved SMS qualification. After making changes, click Submit to resubmit for review. You cannot edit a signature if it has a pending change request (in Pending Review or Under Review status). You must manage the change through the existing request. You cannot edit a signature while a carrier filing request for it is in progress; the Edit Signature button is unavailable in this case. If you need to switch to a different associated qualification, use Add Signature to create a new signature and link it to an approved qualification instead. You cannot directly edit the name of an approved signature because the signature name field is grayed out. The Edit Signature action only changes the signature's source type or associated qualifications. It does not change the signature name, so the `SignName` parameter used in the API remains the same. To change the signature name, you must use the Add Signature feature to apply for a new one.
	File	A dialog box appears, showing the carriers for which you can file the signature and providing suggested actions. Click the File button to manually initiate the filing. You cannot file a signature if it or its associated qualifications have a pending change request (in Pending Review or Under Review status).
	Filing Records	Displays a dialog box with the signature's filing history and results. Check the latest filing result and proceed as described in Real-name registration and filing of signatures.
	One-Click Test	Opens the One-Click Test drawer, where you can run an SMS test to verify the signature's carrier filing status or view past test reports. To use this feature, the following conditions must be met: The signature status is "Available - Normal" or "Available - Abnormal" (excluding severe compliance anomalies that significantly affect delivery success rates). The carrier filing status is "Filed and Pending Verification" or "Filing Successful". You can run a test when the carrier filing status is "Filed and Pending Verification" or "Filing Successful". You cannot run a new test for a carrier while a test is already in progress. One-Click Test is an optional, paid service for verification codes only. You are charged for the SMS messages sent at the standard rate for Messages for Chinese Mainland. For more information, see One-Click Test.
	Clone	Clones the current signature. The system automatically populates the signature parameters. You can modify the information and then click Submit to resubmit it for review.
	Send in Bulk	Click Send in Bulk to go to the Add Sending Task page in the Bulk SMS Assistant. For instructions, see Bulk SMS.
	Freeze	Freezes the signature, making it unavailable (you cannot send messages, apply for templates, file with carriers, and so on). To unfreeze it later, you must ensure all signature information is compliant and accurate.
	Unfreeze	If you need to reactivate a frozen signature, you can manually click Unfreeze. You can also click Edit Signature and submit an update, which unfreezes the signature upon approval.
	Delete	Deletes the signature. This action cannot be undone. Proceed with caution. You cannot delete a signature if it has a pending change request (in Pending Review or Under Review status).

Guidance for compliance adjustments by editing signature source type

If your signature's source type is no longer supported due to carrier compliance policies (for example, the original source was "Launched App/Website/Mini Program"), you can take the following actions:

If the signature name itself meets the requirements for a "full enterprise name/abbreviated enterprise name" or a "registered trademark name", you can use Edit Signature to change the source type accordingly. Upload the required supporting documents, such as a trademark registration certificate or business license, and resubmit for review. After approval, you can resume using the signature.
If the signature name does not meet the preceding requirements, you must apply for a new, compliant signature by using the Add Signature feature.

Review and change history

On the Short Message Service console > Messages for Chinese Mainland > Signature Management > Review and Change History tab, you can view the review details for modified signatures. You can also perform the following operations based on the change type and review status:

Change type	Review status	Actions and description

Export

Both the Signature Management tab and the Review and Change History tab allow you to export signature data to a local file. Click Export to submit an export request. After the request is successful, click Export Records to download the file.

Note

Currently, you can only export all data from the list. The carrier filing status is split into three separate fields in the exported file.
You can export data up to three times per day, with a maximum of 10,000 records per export.
You can export a maximum of 10,000 signatures at a time. A feature to delete all unavailable signatures in a single operation is not available.
If you need to delete signatures by using an API, the DeleteSmsSign operation does not support batch deletion. You must call the operation for each signature individually.
If a user with individual verification deletes a signature, their signature creation quota is not immediately restored. To use the quota immediately, you must upgrade to enterprise verification.
