How Does Branded Calling Work?

There are many terms used to describe branded calling, but they all point to the same core idea: adding context to outbound phone calls so recipients know — and trust — who's calling. That context can include your company name, phone number, logo and reason for the call. Some displays will also indicate the call was verified.

Early branded calling solutions required consumers to download a third-party app. However, the industry has since moved to a standards-based, network-level approach that eliminates the need for apps entirely.

When we surveyed consumers about branded calling, here’s what we found:

• 73% said they're likely to answer calls from businesses that display their company names and logos

• 87% wanted to see the caller's name on their mobile displays — one of the top features they look for

• 64% said verification a call hasn't been spoofed is a critical feature

How is Caller ID Name (CNAM) determined?

Caller ID name — also known as CNAM or Calling NAMe — is the name linked to a phone number. When a call is placed, the caller’s provider sends the number, and the recipient’s carrier queries a CNAM database to retrieve the associated name.

Many businesses assume CNAM updates automatically — that’s not always true. Carriers may rely on third-party databases, and outdated names can cause confusion or lead customers to think a call is spam.

 

Key points:

• CNAM display names max out at 15 characters
• Updates can take up to two weeks
• TransUnion manages the central US CNAM database
• Always update records after switching providers
• Periodically confirm your name displays correctly

Enterprises also undergo number verification and business validation as part of the trusted call process.

What does it mean to brand a call?

Branded calling elevates basic caller ID by showing name, number, logo and call reason. With STIR/SHAKEN and end-to-end authentication, the chances of call spoofing are reduced. Without authentication, a branded call can be just a more convincing piece of spam. With it, it's a trusted communication customers are far more likely to answer.

How does branded caller ID work?

While branded caller ID has a consistent meaning, how it's delivered varies by vendor. TransUnion Branded Call Display relies on a network-level partnership between enterprises and mobile operators.

Through that partnership, the process works as follows:

1. Enterprise onboarding — Your business works with a data management team to pair your phone numbers with the correct names and logos
2. Data management — TransUnion stores and maintains that enterprise data, giving the ecosystem a trusted, central source of truth
3. Query and authentication — The mobile operator retrieves the data and applies it to live calls in real time
4. Device display — Verified call information appears directly on the recipient's mobile screen
