• TFNs offer fastest US SMS origination, simplified registration, and international capabilities to 150+ countries
• Toll-free numbers support 3 Message Parts per Second throughput with carrier-managed opt-out flow
• Registration requires company info, contact details, messaging use case, and opt-in workflow documentation
• Use case details must clearly explain TFN purpose, target audience, and align with selected category
• Opt-in workflow must include brand name, purpose, frequency, support contact, opt-out instructions, and legal links
• Message samples must be 20+ characters, include brand name, match use case, and avoid prohibited content
• Third-party reviewers assess registrations; rejected applications receive update requirements for resubmission
• After activation, monitor SMS delivery closely to maintain carrier compliance and prevent message filtering

Following these steps carefully ensures compliant TFN registration and effective SMS messaging at scale.
