SMS Code Provisioning Guidelines

Use a dedicated extended two-way short code for transaction and marketing sending. Both international and local enterprises use this kind of code. All messages must include a preregistered tag that ranges from 2 to 8 characters at the beginning of the message. This tag must be relevant to the enterprise or brand sending the message. To avoid blocked sends, register all content and URLs,including shortened URLs, before sending. Create the STOP opt-out keyword for marketing messages and include the opt-out response 拒收请回复R at the end of the message, which directs recipients to reply with R to opt out. Because Marketing Cloud Next doesn't permit single character keywords, inbound messages that contain the R keyword are translated to STOP.

Restricted Content

You’re responsible for complying with local rules and regulations. To ensure compliance, familiarize yourself with the legislation of the local market. Failure to comply can result in service suspension, cancellation, and potential fines. China regulates content related, but not limited to, these subjects:

  • Adult
  • Gambling
  • Money lending
  • Multi-level marketing
  • Politics
  • Real estate
  • Religion
  • Stock market trading
