MISSED CALL
VERIFICATION
Cost-Effective Authentication
Verify phone numbers instantly with our cost-effective missed call verification service. No SMS costs, no complex integrations - just simple and user friendly verification.
How It Works
Simple 3-step verification using missed call with PIN extraction from phone number.
Receive Missed Call
User gets a missed call from a random number for verification.
Extract PIN
Last 4 digits of the number serve as the one-time password.
Validate Number
User validates their mobile number using the extracted PIN.

Benefits of Missed Call Verification
A cost-effective solution that enhances your verification strategy
Cost-Effective
Reduces verification costs by using missed calls instead of SMS, with no charge from telecom providers when calls aren't answered.
Enhanced Success Rates
Provides an alternative verification channel when SMS delivery might be delayed or fail, increasing overall verification success.
Complementary Method
Works best as part of a comprehensive verification strategy alongside SMS and IVR calls for maximum reliability.

Perfect Verification Flow
The ideal verification strategy combines multiple methods to ensure maximum success rates while optimizing costs.
Start with Missed Call
Begin verification with the cost-effective missed call method
Automatic SMS Fallback
If missed call verification fails, automatically fall back to SMS
IVR Call as Final Option
For critical verifications, use IVR call as a final fallback method
Before You Implement
Essential considerations for successful missed call verification implementation
Cost Reality
Not 100% free
Charges apply when calls are answered. Proper implementation keeps this to just 3-5% of calls.
Typical Call Distribution
When Charges Occur
Platform Support
Varies by device
User experience varies by platform. Optimized for mobile, not recommended for web.
User Experience
Android
ExcellentAutomatic call interception enables seamless 1-click verification with proper permissions
iOS
FairManual process where users must enter the last 4 digits from their call log
Web
Not RecommendedCross-device experience creates confusion between mobile and desktop
Multi-Method
Never standalone
Helps reduce costs or drive user conversions when traditional methods fall short.
Use Cases
Primary Method
Used with automatic SMS fallback for cost saving
Fallback Method
Used as fallback for SMS for increasing conversions
Implementation Guidelines
Best practices for implementing missed call verification in your application
Confirm the Number

Always ask users to confirm their phone number before initiating verification to avoid wrong numbers and unnecessary charges.
Use our API to validate if the number format is correct before sending verification.
Don't Retry Missed Calls

If missed call verification fails, fall back to SMS instead of retrying the missed call to avoid potential charges.
Multiple missed call attempts increase the chance of users answering the call.
