This blog post explores A2P 10DLC, a messaging standard for businesses in the United States. We'll cover its origins, the benefits of compliance, and how businesses can leverage it for successful communication.

Why A2P 10DLC?

Traditional 10-digit long codes were designed for person-to-person communication. However, they became susceptible to spam and unsolicited messages, eroding consumer trust in SMS. To address this, US carriers introduced A2P 10DLC.

A2P 10DLC ensures:

  • End-user control: Consumers can opt in and out of messaging.

  • Sender identification: Businesses are clearly identified.

This fosters a more secure and reliable messaging experience for everyone. Additionally, A2P 10DLC offers businesses:

  • Increased throughput for messages.

  • Improved brand awareness through dedicated numbers.

  • Greater accountability with clear sender identification.

The Demise of Shared Short Codes

Shared short codes, once popular, have been phased out due to security and spam concerns. With multiple businesses using the same code, regulation became difficult. A2P 10DLC offers dedicated 10DLCs or short codes, enhancing:

  • Privacy: Businesses have their own opt-in and opt-out mechanisms.

  • Campaign Performance: Messaging isn't accidentally blocked due to another company's actions.

Who Needs A2P 10DLC Registration?

Any business sending SMS/MMS messages from an application to US users via a 10DLC number needs to register.

A Streamlined Registration Process

Businesses don't directly register with the Campaign Registry (TCR). Here's how it works:

  1. Choose a Campaign Service Provider (CSP): Select a reputable provider offering robust support and business-focused messaging. Ensure they handle registration.

  2. Brand Registration: Your CSP will register your business with the TCR, establishing your identity with carriers.

  3. Campaign and Use Case Registration: Specify your message types (frequency and purpose). Provide details like use cases, message content, samples, and opt-in information.

  4. Verification and Vetting: The TCR reviews your application and may request additional information. Upon approval, your brand and campaign use case will be scored. You'll receive a 10DLC number (potentially multiple for different campaigns).

  5. Testing and Launch: Your CSP works with mobile networks to update their databases with your confirmed 10DLC number. The number goes through testing before launch.

Benefits of A2P 10DLC Compliance

A2P 10DLC compliance adheres to regulations set forth by major US carriers to improve the messaging ecosystem:

  • Enhanced Security: Businesses and campaigns are registered, reducing the risk of spam or fraud.

  • Improved Deliverability Rates: Verified senders and compliant messages are less likely to be blocked.

  • Better Brand Reputation: Compliance demonstrates a commitment to protecting customers.

Advantages of A2P 10DLC for Businesses

  • Increased Engagement: Local phone numbers build trust and resemble familiar entities.

  • Enhanced Deliverability: Higher chances of messages reaching inboxes due to improved reputation scores.

  • Regulatory Compliance: Ensures adherence to TCPA and CTIA regulations.

  • Cost-Effectiveness and Versatility: More affordable than short codes and toll-free numbers, while supporting SMS, two-way messaging, and voice calls.

Measuring Trustworthiness

The trustworthiness of 10DLC is based on the message use case. Low-risk examples include 2FA (consumers request and expect these messages). Conversely, high-risk examples include third-party marketing (consumers may not have opted in). The assigned score can influence message volume and throughput allowed by carriers.

A2P 10DLC offers improved reliability, trustworthiness, cost efficiency, and increased engagement. Partnering with a reliable VoIP service provider is the first step to unlocking the potential of this advanced messaging solution.
