Description

The Free Caller Registry is an innovative platform created through a partnership between First Orion, Hiya, and Transaction Network Services to simplify the process of registering telephone numbers. This complimentary portal allows organizations that make legitimate outbound calls to submit their information just once through a unified, centralized system, which can affect calls to an estimated 200 million wireless customers in the United States. By registering their numbers, organizations can enhance their reputation, as the provided information is transmitted directly to the three Analytics Engines, which evaluate the data and communicate with the registrants. It is crucial to understand that this platform is designed exclusively for submissions made in good faith, based on a sincere belief that there are issues with mislabeling or call blocking. Moreover, while registering numbers may help address some concerns, it does not guarantee a resolution, since each Analytics Engine performs its own independent evaluation of the submissions received. As such, it remains vital for organizations to ensure that their submissions are accurate and justifiable to maximize their effectiveness in the registry.
