If your business makes outbound phone calls, Free Caller Registry enables you to submit information about your numbers to all major US wireless and wireline carriers for free through one centralized process.
Registration provides a key data point for call protection services to provide the best information possible to those you are calling. While registration does not guarantee that your calls will never be blocked or labeled, it establishes your numbers as belonging to a legitimate business - not bad actors with fraudulent intentions.
Registration information is sent directly to each of the call protection providers that support the major carriers: First Orion, Hiya, and Transaction Network Services. Each provider then follows up directly with the business. There is no need to register any number more than once.
