The future of 10DLC in A2P messaging

A2P messaging is changing as businesses shift toward 10-digit long codes (10DLC) to enhance customer engagement, security, and compliance. 10DLC provides a compliant and scalable messaging option that balances cost and throughput. While short codes are ideal for high-volume campaigns and toll-free SMS supports nationwide engagement, 10DLC offers businesses a localized approach with better deliverability than traditional long codes.

But as carriers tighten compliance and technology advances, what does the future hold for 10DLC in A2P messaging?

Stronger compliance enforcement and changing regulations

Mandatory 10DLC registration

U.S. carriers have mandated that all businesses register their 10DLC messaging campaigns to combat spam and ensure message deliverability. The Campaign Registry (TCR) oversees this process, verifying businesses and their messaging use cases. Failure to register can lead to higher fees, message filtering, or outright blocking, impacting your ability to reach customers.

The deadline for compliance has been extended to early 2025, making it essential for businesses to act now and avoid messaging disruptions.

New authentication and security measures

To strengthen trust, Authentication+ was introduced, requiring businesses to complete extra verification steps before approval. This initiative helps prevent brand impersonation, ensuring that only verified entities can leverage 10DLC.

Authentication+ adds an extra layer of security by requiring businesses to verify their identity through official documentation, such as tax identification numbers, company registration details, and domain-based email verification. This process is designed to prevent fraudulent actors from registering campaigns under false pretenses and ensures that only legitimate businesses with proper consent mechanisms can send A2P messages.

Additionally, Authentication+ helps carriers and regulators establish a clearer chain of accountability, reducing instances of spam and non-compliant messaging. As 10DLC compliance frameworks continue to evolve, businesses should expect further enhancements to verification protocols, making proactive compliance a necessity rather than an option.

Emphasis on consent and content compliance

Even after registration, businesses must adhere to strict content guidelines and obtain clear consent from recipients before sending messages. This practice aligns with regulations and fosters trust and transparency with customers. Implementing straightforward opt-in and opt-out mechanisms ensures that recipients have control over the messages they receive, reducing the risk of complaints and potential penalties.

Additionally, avoiding prohibited content, such as messages related to alcohol, firearms, or adult material, is critical to maintain compliance and protect brand reputation. Regularly reviewing and updating messaging practices in line with industry standards will help businesses navigate the evolving landscape of A2P messaging effectively.

Technological advancements driving 10DLC adoption

Higher message throughput and better routing

Traditional long codes had strict limits on message throughput, often allowing only a few messages per second. With 10DLC, throughput capacity is significantly higher, though it varies based on factors such as campaign type, trust score, and carrier regulations. Businesses should work with their provider to determine the exact limits applicable to their messaging campaigns.

Automated 10DLC registration

The implementation of automated registration systems by some providers like Telnyx has streamlined the process for businesses to register their 10DLC numbers. This innovation reduces the time and complexity associated with manual registration, enabling companies to quickly comply with carrier requirements and commence their messaging campaigns without unnecessary delays.

Enhanced message delivery with carrier failover

To improve reliability, messaging providers are implementing carrier failover mechanisms. When a primary carrier experiences delays or service disruptions, messages are automatically rerouted through an alternative carrier to ensure timely delivery. This approach helps maintain performance and minimizes downtime, particularly for time-sensitive communications.

Businesses using 10DLC should work with their providers to configure failover settings and optimize message delivery across multiple carrier networks.

Business impact and changing industry trends

10DLC vs. short codes and toll-free SMS

10DLC, short codes, and toll-free SMS each serve different business messaging needs. 10DLC offers a balance between cost and throughput, making it a practical choice for businesses that need localized messaging with higher delivery rates than traditional long codes.

Short codes remain the best option for large-scale, high-throughput campaigns, particularly for marketing and promotional messaging. Though they come at a higher cost, they provide superior deliverability and brand recognition.

Toll-free SMS is ideal for businesses looking for a nationwide presence while maintaining strong customer engagement. It allows for two-way communication with verified numbers, making it a preferred choice for customer support and service notifications.

Choosing between these options depends on the specific needs of a business, including budget, volume, and engagement goals. Businesses should assess their use case to determine the most suitable messaging solution.

Growing adoption across industries

As businesses seek compliant and scalable messaging solutions, 10DLC adoption is increasing across various industries, including retail, healthcare, and financial services. Many companies are leveraging 10DLC for customer service notifications, appointment reminders, and transactional alerts. This trend is driven by regulatory enforcement, cost savings, and improved messaging throughput, making 10DLC an attractive alternative for business communications.

Potential for global expansion

While 10DLC remains a U.S.-centric system, other countries are exploring similar A2P registration frameworks. Canada and parts of Europe are considering regulations that align with 10DLC compliance models, hinting at a potential move towards a global standard.

Final thoughts: Adapting to the future of 10DLC

As the A2P messaging landscape continues to change, businesses must navigate compliance requirements, technological advancements, and the evolving role of 10DLC alongside short codes and toll-free SMS. Each option serves different business needs, and selecting the right solution depends on factors such as messaging volume, budget, and engagement goals.

To stay competitive, businesses should:

• Complete 10DLC registration before the early 2025 deadline to avoid disruptions.
• Find the right provider for you that values failover strategies and automation to ensure reliability and efficiency.
• Monitor industry updates to stay ahead of regulatory changes and technological advancements.
