Register your outbound call scenarios to prevent your outbound calls from being flagged as robocalls or spam calls.

To safeguard end users from unwanted calls, phone companies, and apps are working harder to stop or flag suspicious calls that might be spam or fraud. They look for signs like lots of calls in a short time or calls nobody answers. When their internal analytics detect potential unwanted activity, carriers may opt to block calls or apply labels like "Spam Likely," "Telemarketer," "Fraud Likely," or other similar labels to appear on recipients' devices.

To prevent your outbound calls from being mistakenly labeled as unwanted by downstream carriers or applications, we strongly recommend that you proactively register your legitimate outbound calling scenarios through the Free Caller Registry portal. This portal, established by mobile carriers T-Mobile, AT&T, and Verizon, in collaboration with their partnered Analytics Engines—First Orion, Hiya, and Transaction Network Services (TNS)—simplifies the registration process by allowing callers to register their traffic across all systems simultaneously. However, this registration portal may not cover other consumer applications responsible for call labeling or blocking. Make sure to register your Grasshopper phone number with the entities listed in the FCC Call Blocking Tools and Resources.

After registering and providing the necessary details through the portal, the Analytics Engines will review your submission and contact you directly. If your request is accepted, it might take a few days for the changes to your phone number(s) to be implemented. It's important to note that although the registration process doesn't guarantee immunity from future call blocking or labeling, it is designed to minimize the risk of such occurrences significantly. If you have questions for any of the Analytics Engines, please contact them directly.

Mobile device manufacturers could block incoming calls based on their built-in algorithm. Because of this, calls coming into your phone with Grasshopper number as Caller ID may get blocked. Often, having a local phone contact (on your mobile device, not within Grasshopper) with the incoming phone number helps bypass those blocks, as the number is now considered a trusted contact number. Creating a contact on your mobile device with all your Grasshopper phone numbers is recommended to avoid your phone rejecting the call.
