What Does Validated Number Mean on a Call and Why Does It Matter for Your Business

Validated Number is one of the concepts that should gain the most space in Brazilian telephony in the coming years. For the consumer, the idea is simple: when receiving a call compatible with the authentication ecosystem, the device can indicate that that origin has undergone a technical validation process.

Behind this experience is an architecture based on STIR/SHAKEN, certificates, and validation of the identity associated with the call.

Validated Number is not just a name saved in the address book

There is a fundamental difference between a saved contact and an authenticated source. When a user saves a number as "Bank", "Clinic", or "Vendor", the phone only associates that number with a locally defined name. This does not prove that a future link actually came from a legitimate source.

With STIR/SHAKEN, authentication is part of communication between networks. The goal is to reduce the possibility of someone simply presenting a known number without being authorized to use it in that call.

Why this is relevant for companies

Companies suffer when fraudsters use their numbers, brands or identities in scams. Even when the company did not participate in the fraud, reputation can be affected because the consumer believes that he was contacted by the real company.

Call authentication creates an additional layer of protection for your organization's phone identity.

Improves transparency for callers

Helps protect corporate number identity

Reduces the impact of Caller ID spoof-based fraud

Creates a more reliable experience for service and sales

You can work together with RCD to present brand and context

Validated Number and RCD are different things

The seal or indication of validated origin is linked to authentication. Visual and contextual elements—such as company name, logo, and reason for call—are associated with the enriched data layer, such as RCD.

Therefore, a modern business telephony strategy should not only think about appearing on the screen. The goal should be to unite visual recognition and technical confidence.

How Voicecorp uses this concept

Voicecorp directs its strategy towards STIR/SHAKEN and Verified Source. The goal is to bring call authentication to companies that use voice as a critical relationship channel, allowing the corporate phone to keep up with the security evolution that has already occurred in other digital channels.

The future of telephony is not just about showing who is calling. It is to allow the network to confirm the origin of the call.
