Spoofed call protection allows enterprises to digitally authenticate their outbound calls themselves. If a call isn’t really coming from the enterprise, the solutions help communications service providers (CSPs) mark the call as spam or block it. That’s especially important for organizations concerned about their phone numbers being spoofed, including financial institutions, healthcare providers, insurance companies, government agencies, utility providers and more. If calls aren’t authenticated, recipients don’t really know who’s calling.

Call authentication is a method by which call origins are verified so only legitimate calls are delivered to consumers, helping reduce call spoofing. STIR/SHAKEN call authentication has been implemented by all the major communications service providers in the US, and many of the smaller providers, along with robocall mitigation solutions. TransUnion call authentication offers an additional layer of protection by leveraging STIR/SHAKEN AND our end-to-end verification process. In addition, verification information is delivered by STIR Out-of-Band (OOB) to overcome network limitations. That way, the customer’s mobile carrier always knows whether it’s safe to deliver the business’s rich call content to customers.

With Spoofed Call Protection, the terminating service provider (TSP) verifies the call was originated by a legitimate enterprise — tackling the risk of fraudsters spoofing the enterprise’s telephone numbers head-on. The TSP retrieves call authentication data from the TransUnion Call Session Registry (CSR) to validate the call was initiated by the enterprise and apply the appropriate call treatment.
