Unwanted telemarketing and scam calls aren’t just an inconvenience—they cost US businesses time and money. From fake “Google listing” updates to fraudulent bank calls, scammers use sophisticated tricks to reach companies through their landlines.
According to the FTC’s 2024 report, small businesses lose an estimated $2.8 billion annually to phone scams. The good news is that business owners have several tools and strategies to block nuisance calls and protect their staff.
Why Are Businesses in the US Targeted by Nuisance Calls?
Common reasons include:
-
Public listings: Company numbers appear in directories and online ads.
-
Robocall automation: Scammers use dialling software to target hundreds of businesses at once.
-
Vendor impersonation: Fraudsters pose as banks, payment processors, or service providers.
-
Lead farming: Illegitimate “marketing agencies” harvest business data for resale.
Small businesses and home offices are often targeted because they have fewer IT security layers.
Summary: US businesses are targeted because their numbers are public, easy to reach through robocalls, and often lack robust phone security systems.
What Are the Risks of Nuisance Calls for Businesses?
Ignoring the problem can lead to:
-
Lost productivity: Staff spend hours handling irrelevant calls.
-
Financial loss: Scammers request fake payments or sensitive information.
-
Reputation damage: Falling victim to a scam undermines customer trust.
-
Data breaches: Employees may unknowingly share confidential data.
Example: In 2025, a Florida accounting firm reported losing $8,000 after receiving spoofed “IRS” calls requesting verification details for business accounts.
Summary: Nuisance calls cause financial losses, productivity decline, and data-security risks for US companies.
How Can US Businesses Protect Their Landlines?
Here are effective steps to safeguard your lines:
-
Register with the National Do Not Call Registry – Reduces legitimate telemarketing calls.
-
Use a commercial call blocker – Devices like CPR Call Blocker Protect or Nomorobo Business filter robocalls and known scam numbers.
-
Enable carrier-level filtering – AT&T ActiveArmor, Verizon Call Filter, and Spectrum Call Guard all include business solutions.
-
Train employees – Teach staff to recognise red flags such as urgent payment requests or fake verification questions.
-
Implement call-screening software – Tools like Grasshopper and RingCentral let you block or reroute suspicious numbers.
-
Report scams – File reports with the FTC and the FCC to support enforcement efforts.
Summary: Register with the Do Not Call list, use call-blocking tools, enable carrier filters, train staff, and report scams to protect US business landlines.
How Technology Strengthens Business Protection
Businesses can integrate multiple technologies for layered defense:
-
Auto-attendants or IVR systems – Force callers to select options, deterring robocalls.
-
Whitelist databases – Allow only pre-approved vendor or client numbers.
-
Call analytics dashboards – Track call origins and identify scam trends.
-
CRM integration – Flag known contacts automatically, reducing manual screening.
Example: A New York insurance firm implemented a cloud IVR combined with CPR Call Blocker devices and reduced spam calls by 85% in six weeks.
Summary: Combining IVR, whitelisting, analytics, and CRM tools creates a layered barrier that keeps scammers out and customers connected.
