SMS Code Provisioning Guidelines
Use a custom alphanumeric code with an international long code set up for one-way transactional sending. Manage opt-outs with a web link or customer preference center. Alphanumeric codes must be associated with the brand, enterprise, product, or service. These codes can include only alphanumeric characters and spaces.
Local enterprises register their alphanumeric code by submitting this information:
- Sender ID registration form
- Trademark certificate, if the sender ID differs from the enterprise name
- Vietnamese trade license
- Operating license of the Department of Education (for local education brands)
For OTP content, local enterprises must supply this information:
- Screenshot of all OTP steps from the website or app
- Screenshot of website footer with company name, address, and business code
- Certificate of website domain name registration, including a letter of authorization for websites that don't match the brand
- Sender ID Registration form that matches the trade license or the signature of a senior executive that appears on the enterprise's website
- Vietnamese letter of authorization
- Vietnamese registration form
- Copy of trade license, business license, certificate of incorporation, or similar document valid for at least one month
- Copy of a trademark certificate for all of a parent enterprise or holding company's brands, goods, or services
