    Registering the Sender Name with Traficom<\/b><\/span>\u200b<\/p>

    2. \u200bOnce Traficom has processed and approved the registration application, the company will be notified of the approved sender name.<\/span><\/span> Valid SMS Sender IDs can be found at: Registered SMS Sender IDs | Traficom<\/a><\/span><\/strong>.\u200b<\/span><\/span><\/span><\/li>
