Apply for a digital short message signature

Usage notes

• Before you apply for an SMS signature, you must apply for the necessary qualifications based on the qualification document instructions.

• If you are applying for a signature for third-party use, you must provide a letter of authorization that meets the format requirements when you submit the application.

Procedure

1. Log on to the Short Message Service console.

2. In the left-side navigation pane, choose Digital Short Message > Signature Management.

3. On the Digital Short Message Signatures page, click add signature and fill in the Basic Information and Other Information sections as prompted.

   • Purpose of Associated Qualification:

     • Personal use: Select this option if the enterprise or individual information for the selected Signature Source matches the real-name verification information of this Alibaba Cloud account.

     • Third-party use: Select this option if the enterprise or individual information for the selected Signature Source does not match the real-name verification information of this Alibaba Cloud account.

       • Power of attorney: When you set Associated Qualification Type to Third-party use, you must associate a power of attorney. The system automatically displays a list of valid powers of attorney that match the selected Qualification Information. If no power of attorney is available, click Add Power of Attorney to add one. For more information, see Instructions for completing a power of attorney.

         Note

         The system automatically extracts approved but unnamed powers of attorney from your previously approved third-party qualifications. You can select these documents when applying for new signatures. They are named in the format Authorizer Enterprise NameVVersion Number.

         For example, if the authorizer in a previously submitted power of attorney was Cainiao Network Technology Co., Ltd., the default name is Cainiao Network Technology Co., Ltd.V1.

   • Associated Qualification Name: Select the qualification to which the signature belongs from the drop-down list. To prevent rejection, choose an approved qualification. If no qualification is available, apply for a qualification first.

   • Signature Source: Your signature must have a verifiable source to prove ownership. The signature name must correspond to the selected Signature Source. For example, if the Signature Source is Enterprise or public institution name, the signature name must be the full or abbreviated name of the enterprise or public institution. The available signature sources differ for individual and enterprise verified users. Select a Signature Source based on your business requirements.

     Note

     • If the Signature Source option you need is unavailable, note the following: Signatures for Personal use by individually verified users cannot pass the carrier's real-name registration. To proceed, you must apply for and associate a Third-party use qualification, or change your individual verification to enterprise verification.

     • If your business is in the development or testing phase, use the Quick Learning and Testing feature in the console or wait until your service is officially launched before applying for a signature.

     • For government agencies, select Enterprise or public institution name as the Signature Source. Choose the source that best fits your situation.

     • The enterprise must own the registered trademark. The trademark must be searchable on the China Trademark Office website, and the owner listed on the trademark must match the enterprise's name.

     • If Signature Source is Registered Trademark Name:

       • Screenshot of Trademark Details: If you select Registered Trademark Name as the Signature Source, you must upload a screenshot of the trademark details. See Steps to capture a screenshot of trademark details and Screenshot requirements for trademark details.

     • If Signature Source is Launched App (This is no longer supported by carriers. Click to view policy details):

   • Signature Name: Enter a signature name. Do not enter the square brackets 【】. The system automatically adds the brackets 【】 and places them at the beginning of the message content when an SMS message is sent. The signature name must be the sender's full name, abbreviation, or legally registered trademark to clearly identify the sender. Generic or ambiguous signatures are not supported. For more information, see Signature Specifications.
