When the phone rings and the screen shows an unknown number, most of us make the same decision: we let it ring.
According to Pew Research, nearly 80% of Americans ignore calls from unidentified numbers.
For businesses, this simple reflex is a serious problem—especially for contact centers whose performance depends on outbound call success. If your number isn’t recognized or trusted, you’re likely being ignored, flagged, or blocked altogether.
In 2025, ensuring your number is verified, branded, and visible is no longer optional. It’s a critical piece of outbound strategy. And that’s where Verified Caller ID, backed by STIR/SHAKEN protocols, comes in.
💡Why Customers Don’t Answer Unknown Numbers
Imagine this: You’re expecting a call from a delivery service, but a random 12-digit number pops up on your phone. You hesitate. It looks generic—no name, no location—so you swipe it away. This scenario repeats millions of times a day. And while it’s understandable from a consumer perspective, for call centers it’s a disaster.
Unrecognized numbers, especially those flagged by carriers, dramatically lower your call answer rate. And once your number is labeled as spam—even incorrectly—it can take months to recover. Verified Caller ID offers a solution: it builds trust into the call before it even starts, making it more likely your customers will actually pick up.
“Trust is everything. Verified caller ID isn’t just a technical upgrade — it’s a business advantage. When customers recognize who’s calling, they’re far more likely to engage.”
– Mike Mcguire, Chief Revenue Officer at NobleBiz
What Is Verified Caller ID?
In a world flooded with spam and scam calls, verified caller ID acts like a digital passport for your business. It proves to carriers - and, more importantly, to your customers — that your call is legitimate before it even rings. Instead of showing up as a random number, your calls display a trusted identity, turning hesitation into connection.
Definition and Purpose
Verified Caller ID is a technology that authenticates the identity of the calling party. Backed by the STIR/SHAKEN framework (Secure Telephone Identity Revisited / Signature-based Handling of Asserted information using toKENs), it helps ensure that the caller’s identity matches the number displayed on the recipient’s phone.
This verification stops spoofing and fraud while simultaneously signaling legitimacy to the carrier and the end user. When combined with branded caller ID - where your company name and sometimes even your logo appear—your calls stand out from the sea of spam.
How It Works
Here’s what happens under the hood:
- Your call is digitally signed and authenticated by your provider.
- The call metadata travels with it, informing carriers that the number and identity have been verified.
- On the customer’s screen, your business name appears, providing immediate recognition and assurance.
Pro tip: NobelBiz integrates this into your outbound system via our Cloud Contact Center Solution , making verified delivery seamless and compliant.

Why Verified Caller ID Improves Answer Rates
Today’s call environment is unforgiving. Consumers are bombarded with unknown numbers and spam, making them more likely to screen calls or block numbers outright. Verified caller ID cuts through that noise by providing immediate legitimacy. When your number is verified, it not only earns trust from the person receiving the call, but it also receives better treatment from carriers. Calls are more likely to be delivered cleanly, without delays or downgrades.
Trust Drives Response
Trust is the biggest factor in whether someone picks up the phone. Verified or branded calls provide a sense of safety - customers are far more likely to answer when they recognize the name on the screen. It transforms your call from suspicious to expected.
According to YouMail’s Robocall Index, the U.S. receives over 4 billion robocalls monthly. In that noisy environment, legitimacy is everything.
Carrier Priority and Call Routing
Verified numbers receive better treatment from carriers. They’re routed with fewer delays, and most importantly, they’re far less likely to be flagged or blocked by spam filters.
This improved routing leads to better call deliverability, ensuring your calls actually reach your audience, not their voicemail.
And with better answer rates come better conversion rates, higher ROI, and fewer wasted calls.

What You Need to Get Verified
Verification is both a technical and a strategic process. You need a provider that supports STIR/SHAKEN, a number clearly tied to your brand, and ongoing monitoring to maintain trust. Without consistent upkeep, even verified numbers can lose credibility.
STIR/SHAKEN Compliance
You’ll need to work with a provider that supports STIR/SHAKEN protocols. This includes registering your numbers, authenticating your identity, and working through national verification gateways.
At NobelBiz, we simplify this through our Cloud Contact Center Solution , which includes built-in support for STIR/SHAKEN and real-time verification flows.
Consistent Brand Identity
Caller ID doesn’t just reflect your number - it reflects your brand. Aligning your outbound numbers with your business name and regional targeting improves both answer rates and customer trust.
Using a trusted Voice Carrier is key to making sure this branding is consistent across all carrier networks.
Ongoing Monitoring
Even verified numbers can lose reputation if they’re abused. This is why it’s essential to monitor call behavior, answer rates, and spam labeling. NobelBiz provides dashboards that give you full visibility into your number performance over time.
