Short Message Service:Register a sender ID

What is a sender ID?

A sender ID is an alphanumeric name that identifies the sender of an SMS message, typically a shortened company name or brand identifier.

Advantages

• Improve brand awareness: Recipients see your sender ID instead of a phone number.

• Ensure compliance: It ensures that the sender's identity is authentic and legitimate, preventing spam.

• Enhance delivery rate: Carriers use sender IDs to identify the message source, reducing the risk of messages being blocked.

Why register in the console?

Carriers of different countries and regions have different requirements for sender IDs. You may need to prepare a wide range of documents.

To streamline this complex process, Alibaba Cloud SMS collects country-specific filing requirements and automatically formats your information to meet submission standards. You only need to fill in the required fields. This saves you time and increases the approval rate.

      After selection, the system may display the estimated time required for registration.

      

      The SMS console does not support sender ID registration for some countries or regions because:

      • The destination requires a paid sender ID.

      • The destination has regulatory requirements for message compliance and user privacy protection.

      In such cases, follow the prompts in the pop-up window.

      The following prompt indicates that you must apply for a paid sender ID. Contact your account manager for offline registration. Applies to countries such as Russia, Cambodia, Vietnam, Serbia, and Kazakhstan.

      The following prompt indicates that the registration cannot be processed through Alibaba Cloud SMS. You must handle the registration with the local authorities and contact your account manager for configuration. Applies to countries such as Singapore.

   2. Basic information: The basic information varies based on the selected Destination Country/Region. Fill in all required fields accurately.

      The carrier will review your submitted information, such as brand name and URLs, to determine the applicable sending rules (such as whether you can use local or international channels). You must send messages in accordance with the submitted information and designated rules.

      

   3. SenderID: Name your sender ID and provide sample messages.

      • SenderID: Enter a custom sender ID that is related to your company or brand name. It supports letters, digits, and some symbols. An alphanumeric ID can be up to 11 characters, while a numeric-only ID can have up to 15 digits. Chinese characters and other languages are not supported.
