Overview
Before you can send text messages or make in-app calls with Element451, your school must register its Element451 phone number(s). This ensures reliable delivery and compliance with carrier regulations.
For texting, this is part of A2P 10DLC registration, required by mobile carriers to reduce spam and improve deliverability. You can check your registration status anytime in Element451.
For voice calls, Element451 registers your phone numbers with national carrier databases to help prevent call blocking and spam labeling. We also set a CNAM, allowing you to customize the Caller ID name that some carriers display alongside your number.
Note: This self-service registration feature was implemented on 02/24/25. Partners who were utilizing SMS/MMS through Element451 with an assigned phone number before this date are already registered and require no action.

Checking Your Registration Status
When you access the Phone Number Registration page, you’ll see a status card displaying your current registration progress. This includes the status of four key registration components:
Organization: Verifies your brand identity for messaging compliance.
SMS: Ensures your number is authorized to send SMS messages.
SHAKEN/STIR: Confirms caller ID authentication to prevent spoofing.
CNAM: Registers the caller name displayed on outbound calls.
Voice Integrity: Helps verify your phone number’s trustworthiness for voice calls.
Each component will show one of the following statuses:
Accepted: Registration is complete and approved.
Pending: Registration is in progress.
Failed: An issue occurred; contact customer support for assistance.
Without an accepted registration status, you won't be able to send SMS/MMS messages or make outbound calls from Element451.
Partners onboarded before March 1, 2025, may see a Not Submitted status for SHAKEN/STIR, CNAM, and Voice Integrity registrations. This appears to be a display issue, and we are working to resolve it after a data migration. However, if you have any issues making outbound calls via in-app calling, please contact Customer Success.
