Using a non-secure website (HTTP instead of HTTPS) poses both security and compliance risks, which is why Twilio, The Campaign Registry (TCR), and Textline require HTTPS for brand and campaign registration.
Security & Data Integrity
HTTP connections are not encrypted, meaning any data transmitted between a visitor’s browser and the site can be intercepted or modified.
HTTPS ensures the authenticity of the website and protects against spoofing or man-in-the-middle attacks.
Brand Verification
TCR and carriers use website verification as part of their vetting process to confirm that a brand is legitimate and trustworthy.
A lack of HTTPS is seen as a red flag - potentially signaling an outdated, insecure, or fraudulent business presence.
Compliance
Messaging ecosystems (A2P 10DLC, TFN, etc.) operate under carrier and registry rules that require secure digital properties to prevent abuse, phishing, and spam.
HTTPS is a baseline compliance standard for all enterprise communications involving customer data or brand verification.
Deliverability
Unsecured links can trigger carrier filtering, lower trust scores, and even block campaigns - reducing message deliverability.
HTTPS links, on the other hand, improve credibility and help ensure messages aren’t flagged as unsafe.
How to Confirm Your Site Is Secure
✅ Website URL begins with https://
✅ Lock icon appears in the browser address bar
If your site shows http://, work with your web host or IT provider to enable SSL before submitting registration.
