Caller ID Reputation

Caller ID reputation is how carriers and call analytics companies judge whether calls from a phone number are wanted, which affects whether calls get labeled or blocked.

Major US carriers work with analytics companies to score incoming calls. Hiya, First Orion, and TNS are three of the big ones. They look at signals such as how many calls a number makes, how short those calls are, how often people decline or block them, complaint reports, and STIR/SHAKEN attestation. If a number looks risky, the call might show "Spam Likely" or "Scam Likely," or be blocked.

Legitimate businesses can end up with a poor reputation, often from high call volume to people who do not expect the call.

Ways to build and keep a good reputation:

• Call people who gave consent and expect to hear from you.
• Register your numbers with the Free Caller Registry, which sends them to Hiya, First Orion, and TNS. It is free, though it does not guarantee a label will be removed.
• Get A attestation from your phone provider by verifying your business.
• Set a clear CNAM.
• Honor stop requests right away.
• Watch your answer rates by number for sudden drops.

Avoid tactics meant to dodge filters, like cycling through lots of numbers. Those patterns are exactly what analytics systems are designed to catch, and they damage trust.
