Your customers ignore calls from numbers they don't recognize. Branded Calling fixes that by showing your verified business name, logo, and the reason for your call right on the recipient's screen, before they pick up. Instead of an unknown number or a "Spam Likely" warning, people see who you are and why you're calling. Branded Calling works automatically with your Telnyx outbound SIP trunking calls once your brand and numbers are approved.
Most people won't answer a call they can't identify. That means missed appointment reminders, ignored delivery updates, and account notifications that go straight to voicemail. Branded Calling turns an anonymous number into a recognizable, trusted call, so more of your calls get answered and your team spends less time chasing callbacks. It works as a positive identity layer that lifts answer rates and trust signals, and Telnyx handles all of the ecosystem interactions on your behalf, so you work only with the Telnyx portal and API.
You register your business as an Enterprise and create a Display Identity Record (DIR) that defines what recipients see: your display name, logo, and call reasons. Telnyx vets the DIR, verifying your business identity, IP ownership, and compliance. You then associate your Telnyx phone numbers with the approved DIR.
When you place a call from one of those numbers, Telnyx signs the call with a cryptographic token carrying your DIR's rich call data, built on top of the STIR/SHAKEN call-authentication framework. The terminating carrier verifies the signature and renders your branded information on the recipient's device. Branded Calling runs on an industry-wide registry managed by CTIA, which keeps trust consistent across participating carriers.
Branded Calling currently applies to US-to-US calls placed to US mobile numbers serviced by T-Mobile and Verizon. Approval makes your brand and numbers eligible to send verified identity information, but display is not guaranteed on every call. Whether branding appears depends on the receiving carrier, the recipient's device, and the network path the call takes.
