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.
⏱️ SMS Registration Timelines
A2P 10DLC (SMS) registrations undergo a multi-step review by mobile carriers and SMS registries. While the standard review window is 2–3 weeks, approvals have historically been completed in as little as 7 days.
As of January 2026, review timelines have lengthened. Some registrations may take longer than 3-4 weeks. These delays are outside of Element451’s control and are due to carrier and registry backlogs due to enforcement of additional (unannounced) regulatory requirements.
Before You Begin
Phone registration requires a publicly accessible Privacy Policy and Terms of Service webpage(s) that includes information concerning SMS (text) messaging and how phone numbers are used and shared.
These samples can be used as starting point and covers key items, but you should consult with your administration and counsel before using adding any privacy policy or terms language to your website.
Sample Privacy Policy
Sample Terms of Service
📌 Note: Industry best practice is to maintain these policies on separate pages or URLs, even if they may sometimes be published together. Clearly defined and distinct policies tend to achieve higher approval rates during regulatory reviews. If policies are combined on a URL, each must be clearly separated with appropriate titles and headers, and presented as distinct, independent documents.
Obtaining Consent (Opt-in)
Before sending SMS messages, recipients must provide explicit consent (opt-in) to receive text communications.
Wherever you collect mobile phone numbers—such as inquiry forms, event registrations, or applications—you should ensure that consent is clearly obtained at the point of collection.
Your forms must also include a brief regulatory disclosure that:
States the user is opting in to receive SMS messages
Includes links to your Privacy Policy and Terms of Service
This helps ensure compliance with messaging regulations and protects both your institution and your recipients.
For example:
By providing your mobile phone number and selecting yes, you agree to receive informational and transactional text messages regarding your admissions and enrollment, application status and event reminders related to your submission. Message frequency varies. Message and data rates may apply. Consent is not a condition of enrollment. Reply STOP to opt out at any time. Reply HELP for assistance.

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 is simply a display issue. However, if you have any issues making outbound calls via in-app calling, please contact Customer Success.
CNAM Updates
CNAM (Caller ID Name) is the text name associated with a phone number that may display on a recipient’s caller ID alongside the number. Unlike the numeric caller ID itself, CNAM is looked up by the receiving carrier from national caller name databases based on your phone number.
🕒 Timing of CNAM Updates
When a CNAM update is submitted:
It typically takes about 7–10 business days for most carriers to refresh and begin showing the new name.
Full propagation across all networks can take 1–4 weeks or more, depending on how often carriers update their local records.
You may see the new name on some networks earlier than others during this propagation period.
📶 Carrier Differences Matter
Whether and when CNAM displays depends on the receiving carrier:
Landlines: Most landline networks regularly query name databases and are more likely to show the registered CNAM.
VoIP carriers: Behavior can vary; some look up CNAM regularly while others may cache results or use external services.
Mobile carriers: Many mobile carriers either don’t use traditional CNAM lookups or require subscribers to enable the feature. This means CNAM may not appear consistently on mobile phones, even after it’s updated.
Because each carrier maintains its own update schedule and database subscriptions, display of the CNAM is ultimately controlled by the recipient’s carrier, not by the phone number owner or network.
