How to Register Your Numbers
Creating a Hiya account is free and instant.
After account creation and number upload, full registration typically completes within 48 hours.
Step 1. Create a Hiya Account
Visit Hiya’s Number Registration page and sign up using the Get Started or Create Free Account option. Select Hiya Connect: Number Registration during setup.
If you prefer not to create an account, you can submit a one-time registration request through the Hiya Help Center. This option registers your numbers for 180 days.
CloudTalk recommends using the full Hiya portal, as registrations do not expire and additional features such as branded calling and analytics become available.

Step 2. Verify Business Information
During account setup, provide the required business details so Hiya can verify your organization.
Step 3. Register Phone Numbers
After your account is set up, log in to the Hiya self-service console.
Open the Phone Numbers section from the left-hand menu.
Click the Phone Numbers section in the top right corner
You can add phone numbers manually or upload them using a CSV file in E.164 format, such as +441234567890.
Phone numbers can be uploaded in sets or jobs. This allows you to assign internal names and group numbers by department or use case.
Once submitted, Hiya’s Vetting Services team reviews the numbers.
During review, numbers appear with a Pending status. After approval, the status updates to Registered.
Phone Number Statuses
Each number appears with one of the following statuses:

Step 4. Manage Registered Numbers
You can add or remove numbers at any time and monitor their registration status.
The Hiya dashboard shows which numbers are active and provides key statistics related to number usage.
If you upgrade to Hiya Branded Calling, the dashboard also displays usage data for branded calls alongside number registration data.
Risk Ratings and Call Reputation
Hiya assigns risk ratings to phone numbers based on calling behavior. Monitoring these ratings helps you adjust calling patterns to maintain a positive reputation.
Risk levels include:
Low risk
A spam label is very unlikely.
Moderate risk
A spam label is possible.
Labeled spam
A spam label is very likely.
Selecting a phone number opens a report card showing which factors contribute to its risk rating.
Risk Factors | Carriers' Flagging Logic | Recommendations |
Maturity: age and volume of the call history | Carriers see cycling and rotating numbers as a sign of "likely sales" calls or "likely spam" calls. |
Spam flags usually resolve once healthy traffic behavior is established. |
Connection: answer rates and abandon rates of the calls | Carriers consider low answer rates as another strong indicator of sales and telemarketing traffic. |
|
Engagement: how long your customer stays on the line once you are connected | An average call duration longer than 45 seconds is generally considered healthy. |
|
Sentiment: how consumers react after getting calls from you | Sentiment reflects how recipients react after receiving calls, including blocking numbers or reporting calls as spam. Some carriers, including AT&T, place strong weight on this feedback. | Let the customer know why you called them.
