Frequently asked questions about CNAM caller ID 

CNAM Caller ID displays your business name next to your phone number by connecting to national databases, making calls more recognizable and increasing answer rates. 

Basic caller ID only shows a number. CNAM adds your name, so recipients know it’s you and are more likely to pick up. 

Yes. Businesses from healthcare and finance to contact centers use recognizable caller ID names to make calls feel safe and familiar. 

STIR/SHAKEN verifies number ownership while CNAM displays the name. They work together for a trustworthy experience, but alone, neither fully eliminates fraud or guarantees compliance. 

You’ll need Sinch Voice connectivity or carrier interoperability. Integration with CNAM databases is included. 

Sinch offers nationwide U.S. coverage through 450+ carrier interconnects and authenticates billions of trusted calls each month. 

No. CNAM supports STIR/SHAKEN compliance, but full compliance requires multiple layers. Neither solution alone guarantees complete protection. 

By using call treatment rules and trusted data sources, CNAM helps block spoofed or fraudulent calls before they reach your customers.
