Industry Background

Over the past few years, the messaging industry has undergone significant changes. Businesses frequently use text messaging to send alerts, appointment reminders, notifications, and marketing promotions to customers. However, with this growth, there has also been a rise in spam messages and a decline in message quality.

To address these issues, U.S. mobile carriers like AT&T, US Cellular, and T-Mobile are implementing new standards to reduce spam and maintain message quality. These changes include registration processes and message blocking for non-compliant 10DLC phone numbers


OneLocal's Compliance Approach

To align with these industry standards, Twilio, our messaging partner, has introduced requirements to register OneLocal customer numbers. This ensures compliance and enhances text deliverability. As part of this initiative, OneLocal is automatically registering all existing customers sending messages to U.S. recipients. This measure helps ensure compliance with new standards and minimizes the risk of message blocking


Benefits of A2P 10DLC Registration

Messages sent via OneLocal to U.S. recipients will benefit from:

  • Improved Trust and Authority: Enhanced deliverability under the A2P 10DLC protocol

  • Faster Delivery Speeds: Messages delivered at higher throughput rates.

  • Compliance Assurance: Adherence to carrier requirements


Key Definitions

  • A2P: Stands for “Application to Person” messaging, referring to messages sent from an application to an individual, typically without expecting a reply.

  • 10DLC: Stands for "10-digit long code" messaging, allowing businesses to send sanctioned A2P messages via local phone numbers.

  • Standard Brand: Refers to businesses sending fewer than 3,000 SMS/MMS messages daily across major U.S. networks or fewer than 1,000 messages per day to T-Mobile customers


Registration Requirements

To register as a Standard Brand and Campaign, businesses must provide the following information:

  • Legal business name

  • Taxable business address

  • EIN Business Number/Tax ID

  • Industry

  • Phone number

  • Primary contact name

  • Primary contact title

  • Primary contact phone number

  • Primary contact email address


Additional Considerations

If your business plans to send more than 3,000 texts per day to all U.S. carriers or more than 1,000 texts per day to T-Mobile customers, please contact your marketing specialist. This level of messaging requires additional registration and incurs extra monthly fees
