At CloudTalk, we take proactive steps to ensure your calls reach customers without being flagged as spam. In this guide, you’ll learn how we protect your outbound numbers through verified registration, call authentication standards, and ongoing reputation management.

​
✅ Verified Business Registration

We register CloudTalk’s US numbers with leading call analytics providers like Hiya, (which includes First Orion and TNS), and Numeracle. These platforms collaborate with major US carriers (AT&T, Verizon, T-Mobile) to verify business callers and reduce the chances of your numbers being mislabeled as spam.

​
✅ Stir/Shaken Compliance

CloudTalk uses Tier 1 carriers in the US that are fully STIR/SHAKEN compliant, which helps authenticate your calls. By default, your calls are sent with A or B-level attestation.

​
✅ Caller ID Name (CNAM) & Branded Calling

CNAM (Caller Name Delivery) is the traditional method used mainly for landlines. It displays your company name when a call is received, if the carrier supports it. CloudTalk stores your CNAM records free of charge for all US numbers. However, CNAM is limited and inconsistent across mobile networks. For more reliable branding on mobile phones, CloudTalk supports Branded Calling - a modern solution that allows carriers to display:
  • Your company name
  • Your logo
  • The reason for the call
Where supported, this significantly increases answer rates and builds trust with customers.
