SMS Code Provisioning Guidelines
Use a custom alphanumeric code with an international long code set up for one-way sending. These codes support both marketing and transactional sends. 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 alphanumeric code requests before you can send messages.
