Frequently Asked Questions
Are these real phone numbers?
No, all phone numbers are generated algorithmically for demonstration purposes. They are not connected to any real telecommunications network and cannot receive actual SMS messages.
How often do numbers and messages change?
Numbers and messages refresh daily at midnight UTC. This provides fresh content while maintaining consistency for testing scenarios throughout each day.
Can I use this for production systems?
This platform is designed exclusively for development, testing, and demonstration purposes. It should never be integrated into production systems or used for real user verification.
How do I copy verification codes?
Click on any message containing a verification code to automatically select it. Then use Ctrl+C (Windows/Linux) or Cmd+C (Mac) to copy the code to your clipboard.
Why do pages auto-refresh?
Inbox pages automatically refresh every 30 seconds to simulate receiving new messages in real-time, providing a more realistic testing experience.
What countries are supported?
We provide virtual numbers for over 100 countries worldwide, each with authentic formatting and regional characteristics to support comprehensive international testing scenarios.
Technical Information
Number Generation
Phone numbers use country-specific formatting and realistic prefix patterns. Generation is seeded by country code and date for consistent daily results.
Message Types
Messages cover banking alerts, OTP codes, delivery notifications, social media verifications, and e-commerce confirmations.
Code Formats
Verification codes range from 4-8 digits following industry standards for SMS-based authentication systems.
Update Frequency
Content refreshes daily with 8-15 messages per number, distributed across realistic time intervals within the past 2 hours.
Best Practices
Use different countries to test international SMS formatting and validation
Test your application with various message types and code formats
Verify your parsing logic handles different sender names and message structures
Test edge cases with messages that don't contain verification codes
