A new industry impact report from global phone intelligence provider netnumber sounds the alarm about a phone number validation gap, leaving enterprises vulnerable to billions in losses from voice and texting fraud.

The report reveals how basic validation systems are failing to detect sophisticated telecommunications-based attacks, demonstrating that while phone numbers have become the foundation of digital identity—securing everything from bank accounts to cryptocurrency wallets—most businesses continue to validate these critical numbers using tools designed for basic data hygiene rather than security-critical applications. 

Entitled “The Phone Validation Blind Spot That’s Costing Businesses Millions,” the report cites the need for better phone number intelligence to shore up communications security worldwide and points to alarming data showing real-world consequences of inadequate phone validation, including: 

• SIM swap fraud cases exploded 1,055%, jumping from 289 to nearly 3,000 incidents in the UK alone.
• $48.7 million in losses from SIM swap attacks in the United States, as documented by the FBI’s Internet Crime Complaint Center. 
• According to a recently released Federal Trade Commission (FTC) report, U.S. consumers reported losing more than $12.5 billion to various types of fraud in 2024, including phone calls and text messages, a 25% increase over the prior year.

“Fraudsters have learned to systematically exploit the difference between basic phone validation and true telecommunications intelligence,” said Steve Legge, CEO of netnumber. “While enterprises think they’re protected with phone validation, they’re often using tools that can’t detect when a customer’s number has been hijacked just hours earlier.” 

The impact report also highlights how new eSIM technology has compressed attack timelines from hours to under five minutes, allowing criminals to port phone numbers and drain accounts before traditional validation systems detect the compromise.

Beyond fraud, the impact report documents how inadequate phone intelligence creates massive operational waste:  

• Businesses spend approximately $790 million globally on SMS marketing annually, according to industry research
  
  
• SMS campaigns achieve 98% open rates and generate $71 for every dollar spent, but poor validation leads to significant waste 

• In a Validity survey, 78% of respondents report feeling annoyed by text messages from brands — 28% say they stopped buying from a brand as a result
  
  
• Mobile phone accounts were involved in 48% of all account takeover cases in 2024 

The impact report reveals a critical divide in how businesses approach phone validation. Basic validation services act like smoke detectors—useful for surface-level checks and routine data cleaning, but blind to deeper threats. Telecommunications intelligence networks like netnumber operate more like full fire suppression systems, tapping directly into carrier infrastructure to deliver real-time portability data, fraud pattern recognition, and risk scoring based on live network behavior. Both may alert you to an issue, but only one gives you the intelligence to prevent damage.

“Phone numbers have become the master key to digital identity, but most companies are still validating them like it’s 2010,” Legge said. “The gap between basic phone validation and true telecommunications intelligence is only growing, and companies that recognize this divide will have significant advantages in both security and customer experience.” To read the complete netnumber Impact Report, visit this link:The Phone Validation Blind Spot That’s Costing Businesses Millions, or see the full press release here
