If you rely on phone calls to connect with clients, prospects, or customers, you've likely felt the impact of stricter carrier rules over the last few years. Have you ever wondered why your connection rates dropped, or why important calls are suddenly getting flagged as "Spam Risk"?
The answer often comes down to an industry-standard framework called STIR/SHAKEN.
If terms like attestation levels, Trust Hubs, and profile rejections sound like a foreign language, don't worry. Let's break down what STIR/SHAKEN is, why it matters for your business, and how you can ensure your calls actually reach your customers.
What is STIR/SHAKEN?
STIR/SHAKEN stands for Secure Telephone Identity Revisited (STIR) and Signature-based Handling of Asserted information using toKENs (SHAKEN).
In plain English, it is a digital caller ID authentication framework designed by telecom regulators to combat illegal robocalling and number spoofing. When a call travels across internet protocol (IP) networks, the originating provider applies a secure "digital signature". Downstream carriers check this signature to verify that the caller actually owns or has permission to use the phone number they are displaying.
Depending on how well a provider knows you and your right to use that number, your call receives an attestation level (ranging from Full "A" Attestation to Gateway "C" Attestation). Calls with lower or missing attestation are much more likely to be blocked or filtered by carrier apps before they ever ring.

Why Did My STIR/SHAKEN or Business Profile Get Rejected?
Many legitimate businesses do everything right, only to find that their initial STIR/SHAKEN or business profile registration has been rejected. This can be frustrating, but rejections usually happen due to minor data discrepancies or verification hiccups.
Common culprits behind a rejected profile often include:
- Mismatched legal business names or addresses compared to official government documents (like your EIN filing).
- Issues verifying the authorized representative.
- Incomplete compliance or documentation details.
If you've run into this roadblock, you aren't out of luck. Review the troubleshooting steps and common fixes outlined in this guide: Why Did My Business Profile and STIR/SHAKEN Get Rejected?
Navigating the Trust Hub: Teams and Individual Users
To make compliance less of a headache, modern communication platforms utilize centralized portals—often called Trust Hubs—to streamline business profile registrations, A2P 10DLC, and STIR/SHAKEN verification in one place.
However, managing these settings requires understanding how permissions are handled across your organization:
- For Individual Users: If you are setting up your profile or working as a single operator, understanding how to configure your account properly ensures your individual user verification stays intact. Learn more in the resource for Trust Hub Individual Users.
- For Teams: If you are managing multiple agents or a broader sales floor, administrative oversight is key to keeping your entire organization compliant and avoiding communication bottlenecks. Check out the guidelines for Trust Hub Teams.
Final Thoughts
STIR/SHAKEN isn't going away—it's the new normal for modern voice communication. While it was built to root out bad actors, it places the burden of proof on legitimate businesses.
By taking the time to properly register your business profile, clear up any verification rejections, and utilize your platform's Trust Hub, you can protect your caller reputation, safeguard your connection rates, and ensure your customers know that your calls are safe to answer.
