Business identity theft, specifically number spoofing, is on the rise. For enterprises, the cost can be missed calls and a weakened brand reputation. Here is everything you need to know about spoofing and how to prevent it with SENTRY® Call Blocking.

What is a Robocall?

To protect your business, you must first understand the threat’s mechanism.

A robocall is a phone call that delivers a pre-recorded message using an autodialer. While some robocalls are legal and helpful(such as flight delay notifications or school closing alerts), the vast majority are illegal robocalls used by scammers to reach millions of people at a low cost.

Why Robocalls Are Dangerous to Businesses

🔊 Volume

Autodialers can make thousands of calls per minute.

⚠️ Deception

Scammers often pair robocall technology with spoofing to make the automated message appear as if it's coming from a local or trusted business number — yours.

🔄 Automation

They require zero human intervention to initiate.

What is Business Number Spoofing?

Spoofing occurs when a scammer or malicious actor deliberately falsifies the information transmitted to your caller ID display to disguise their identity.

Scammers often use “neighbor spoofing” or “brand spoofing” to mimic the phone numbers of trusted organizations (like banks, healthcare providers, or government agencies). Their goal is to trick the recipient into answering the call and providing sensitive information, such as social security numbers or credit card details.

The High Cost of Spoofing: Why Businesses are at Risk

When scammers hijack your numbers, your customers may blame the name on the screen, not the scammer behind the call.

The Impact on Your Brand

Declining Answer Rates: As customers become wary of your “flagged” numbers, legitimate calls go unanswered.

Legal & Regulatory Risks: Spoofed number can lead to an influx of “Do Not Call” complaints against your legitimate business.

Brand Erosion: Customers associate your brand name with harassment and fraud.

Operational Loss: Vital communications (appointment reminders, delivery updates, fraud alerts) fail to reach the intended party.
