How Bad Phone Data Corrupts Analytics and Decision-Making
Corrupted Data Insights
The impact of fake users and invalid phone data goes far beyond just inflated numbers – it wreaks havoc on analytics. Even the most precise analytics tools can’t deliver accurate insights when the underlying data is flawed. Metrics based on invalid phone numbers become unreliable, leading businesses astray.
Bad data costs U.S. businesses a staggering $3.1 trillion every year. It starts with the basics: fraudulent accounts inflate your user base, creating the illusion of growth, while real conversion rates quietly decline. Your performance charts may look promising, but they’re telling a story that doesn’t exist.
The ripple effects of bad data touch every corner of decision-making. Sales teams waste an average of 550 hours and $32,000 annually chasing leads based on inaccurate information. Forecasting models, trained on this flawed data, predict growth that never happens. The result? Biased projections and decisions that crumble under scrutiny.
Impact on Marketing and User Engagement
Corrupt data doesn’t just distort metrics – it also undermines marketing efforts. When marketing teams spend 34% of their time chasing invalid leads, customer acquisition costs skyrocket, while their ability to reach real prospects diminishes.
Take the case of Michael Chen, VP of Marketing at MarketPro, in January 2025. His team was sending out 2.5 million SMS messages every month, but many were landing on invalid numbers. After implementing a phone validation system, MarketPro slashed their SMS marketing costs by 40% and saw a 280% boost in ROI.

Invalid numbers don’t just waste resources – they also harm your campaigns. High bounce rates from these numbers can trigger carrier spam filters, leading to legitimate campaigns being blocked entirely. This not only disrupts delivery but also tarnishes your sender reputation, making future campaigns even harder to execute successfully.
Why Mobile Operators Hold The Keys To Fraud-Proof Sign‑Ins
The Phone Verification API Solution
BatchData’s Phone Verification API helps stop bad data in its tracks by instantly checking phone numbers during sign-ups, subscriptions, or checkouts. With just one API call, you’ll know if a number is valid, active, its type (mobile, landline, or VoIP), the carrier, and its Do Not Call (DNC) status.
This system taps into trusted data sources and real-time risk indicators to flag disconnected, temporary, or fraudulent numbers. It provides the insights you need to stay compliant, block risky virtual numbers, and ensure legitimate users can proceed smoothly.
Real-Time Verification in Milliseconds
When users are filling out forms or making purchases, speed is everything. BatchData’s API delivers results in milliseconds, verifying phone numbers right when they’re entered – whether during registrations, newsletter sign-ups, or payment processes.
Between 2023 and 2024, Intuit rolled out real-time phone verification across more than 200 countries to authenticate new users, achieving a 94% deliverability rate for one-time password messages in just three months. Similarly, Stripe used the API to secure millions of user logins in the United States, boosting login success rates by 6 points, with 70% of verifications handled seamlessly through the API.

This fast and accurate verification process is designed to integrate effortlessly, keeping your system efficient and user-friendly.
Easy Integration for Any Platform
Built on standard REST architecture with JSON data exchange, the API works with nearly any modern platform. Developers can quickly integrate it into web forms or mobile apps using detailed documentation and libraries available for Node.js, Python, and Java.
"What used to take 30 minutes now takes 30 seconds. BatchData makes our platform superhuman." – Chris Finck, Director of Product Management
Whether you’re verifying numbers at your API gateway or directly in web forms, the integration ensures invalid data doesn’t clog up your systems. Plus, with flexible Pay-As-You-Go pricing, you only pay for what you use – no long-term contracts required.
Real Estate Use Cases for Phone Verification
Better User Onboarding
Real estate platforms often struggle with fake accounts, which can mess up their data and make CRM systems less reliable. By using phone verification during sign-up, platforms can prevent invalid numbers from sneaking into their systems.
The Phone Verification API cross-checks phone numbers against a database of 356 million records. It even flags numbers tied to TCPA litigators and Do Not Call (DNC) lists, helping reduce the risk of legal issues tied to TCPA and DNC violations. With data updated every 24 hours and validation sourced from over 50 providers, the system achieves a 99.9% accuracy rate. It also boasts a 76% right-party contact accuracy – three times better than the industry norm.
Cleaner sign-ups mean more reliable data, which translates into sharper marketing strategies.
Higher Quality Marketing Leads
Bad contact data doesn’t just create headaches – it wastes time. Studies show that up to 27% of a sales rep’s time can be lost due to poor data, and 62% of organizations admit that 20–40% of their records are incomplete or inaccurate. For real estate agents trying to connect with property owners or serious buyers, invalid numbers mean hours of frustration.
Real-time phone verification solves this by removing invalid contacts, instantly improving lead quality. Agents working with verified data see contact rates improve by 10–20%. Plus, verification helps pre-qualify leads: prospects who complete two-factor authentication during sign-up are 400% more likely to respond if contacted within the first five minutes. This ensures your team spends time on leads that are ready to engage.
But phone verification doesn’t just stop at better leads – it also plays a key role in securing transactions.
Safer Transactions
With better onboarding and higher-quality leads in place, phone verification adds an extra layer of security to real estate transactions. By validating over 80% of prospects and flagging potential risks like criminal records, bankruptcies, liens, or foreclosures, it helps ensure that sellers are authorized to transfer property titles and that buyers making payments are legitimate.
Additionally, the process creates an auditable trail, proving due diligence in case fraud occurs. For high-risk deals, verifying identities upfront can stop impersonation scams before any money changes hands. This not only protects your business but also builds trust with clients during critical financial exchanges.
