SMS Code Provisioning Guidelines
Use a custom alphanumeric code with an international long code set up for one-way 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 or spaces. Local carriers must approve and allowlist all requests before SMS sends can occur. Alphanumeric codes that don't send messages for a 6-month time frame are blocked without notice and require re-registration. Submit a letter of authorization on corporate letterhead for alphanumeric codes. These letters are signed, dated, and rubber-stamped.
Use local long codes for two-way marketing and transactional sends.
Thailand allows only long URLs in SMS messages. Submit all URLs to carriers for allowlisting before sending.
