Concept: Workday Messaging U.S. A2P Registration

Concept: Workday Messaging U.S. A2P Registration

To configure Workday Messaging for the United States, you first need to run the
Configure One-Way Messaging
 task. When you submit the U.S. messaging configuration information for your company through Workday, it goes to our messaging subprocessor for initial vetting. Next, it goes to The Campaign Registry (TCR) for validation through the Application to Person (A2P) 10-digit long code (10DLC) system. A2P 10DLC messaging ensures that all traffic to U.S. phone numbers is verified and consensual.
The A2P 10DLC registration process takes place outside of Workday and includes registering a:
  • Customer Profile and A2P Trust Bundle.
    • The Customer Profile requires information to validate your business identity, including legal business name, business type, and Tax ID.
    • TCR requires the details from your Customer Profile to determine your trust score.
  • Brand, which identifies your company to the carrier networks so they know that your company is a legitimate sender.
  • Campaign, which includes providing:
    • The use cases of the types of messages your company wants to send.
    • Information about how end users can opt in and opt out.
TCR can take up to 30 days to complete this process. You can view your one-way messaging configuration status on the
Maintain Workday Messaging
 task.

Privacy Policy Guidelines

When you fill out the
Company Information
 section on the
One-Way Messaging Configuration
 task for the U.S., you must add a link to the privacy policy for your company. Use a privacy policy that complies with these A2P 10DLC campaign approval requirements to ensure approval of your messaging configuration:
  • You don't share mobile information with third parties or affiliates for marketing or promotional purposes.
  • You do permit sharing information to subcontractors in support services, such as customer service.
  • All other use case categories exclude text messaging originator opt-in data and consent. You don't share this information with any third parties.

Authorized Representative

When you configure one-way messaging for the U.S., you must enter information about your organization’s authorized representative, including name and contact information. This is the person that TCR can contact to address any validity concerns with the SMS brand and campaigns registered and verified through TCR. You must also select the job position that best matches that of the authorized representative from the
Job Position
 prompt.
When you complete the
Configure One-Way Messaging
 task for publicly-traded, for-profit U.S. companies, the Workday Messaging subprocessor sends the brand representative you entered in the
Authorized Representative
 section a two-factor authentication email. The brand representative must verify their identity by clicking the link in the email within 7 days. Private and not-for-profit U.S. companies don't receive a two-factor authentication email, even though they're also required to enter a brand representative.
