Phone validation saves money by catching invalid, disconnected, and non-SMS-capable numbers before you spend a cent sending messages to them. Every undelivered text still costs you — and across large contact lists, those wasted sends add up to thousands of dollars in unnecessary SMS costs. By validating phone numbers in real time, businesses reduce SMS costs, improve deliverability metrics, and stop paying for messages that never reach a human.
Where Businesses Lose Money (And How Validation Helps)
1. SMS Marketing Campaigns
A 100,000-number contact list with 15% unreachable contacts means paying for 15,000 undelivered messages. Validation cleans lists beforehand by checking line types, deactivation status, and ensuring messages reach actual mobile devices.
2. Two-Factor Authentication (2FA)
Sending OTP codes to invalid numbers wastes funds while frustrating users locked out of accounts. Real-time validation ensures every verification reaches active, text-enabled devices, reducing failures and support burden.
3. Sales and Outreach
Cold calling and SMS prospecting waste rep time and budget on unreachable numbers. Pre-validation filters out dead contacts, prioritizing genuinely reachable prospects.
Real-Time Validation vs. Area Code Guesswork
Outdated databases and third-party sources fail when numbers port or users relocate. CheckThatPhone accesses real-time carrier data in the U.S. and Canada, providing:
- Accurate line type identification
- Deactivation and suspension verification
- Carrier details and portability information
- SMS deliverability assessment
- GeoIP and timezone data
See the API documentation for full details on the data returned with each validation request.
Financial Impact
For 500,000 monthly SMS at $0.0075 each with 12% undeliverable rates, businesses waste approximately $450 monthly or $5,400 annually — before accounting for voice calls and verification failures. Phone validation saves money by eliminating this waste before it happens.
