AT&T is starting to provide TruContact Branded Call Display.
A feature in partnership with TransUnion. The delivery to cell customers uses STIR/SHAKEN protocol to authenticate callers.
Callers need to register with TransUnion.
The incoming calls should display the companies logo, name, phone number and valid number.
The STIR/SHAKEN protocol uses asymmetric cryptography to validate the information displayed.
Only a very few companies are using TruContact Branded Call Display currently.
