SMS Anti-Fraud Solution

Protect OTP / 2FA messages from fraudulent traffic

Fraudulent traffic from fake or inactive numbers drives up costs, strains infrastructure and disrupts critical OTP and 2FA deliveries. Our SMS Anti-Fraud Solution validates numbers before sending, ensuring messages reach genuine customers while cutting unnecessary costs.

The solution is part of the Apifonica Messaging platform and works alongside your existing SMS infrastructure.

How it works

SMS Anti-Fraud Solutions

The verification layer is deployed with onboarding and requires minimal changes to your existing messaging environment.

SMPP / API

Monitoring

Verification trigger

Voice API check

SMS delivery

Easy integration

The system integrates as a standard supplier for existing SMPP or API connections, so clients can add fraud protection without redesigning their messaging workflows or infrastructure.

Real-time traffic monitoring

Incoming SMS traffic is continuously analysed to detect unusual activity, sudden traffic spikes or patterns commonly associated with fraudulent behaviour.

Automatic verification trigger

When predefined traffic thresholds or suspicious patterns are detected, the platform automatically initiates verification using the Apifonica Voice API.

Phone number validation

The verification call confirms whether the destination number is active and belongs to a real recipient. Based on the result, the number status is immediately updated before SMS delivery continues.

Key benefits

Protect OTP and 2FA traffic

Help authentication codes and other critical transactional messages reach genuine customers instead of fraudulent or artificially generated recipients.

Prevent SMS fraud

Identify suspicious traffic patterns early and stop fraud before it generates unnecessary messaging charges or impacts platform performance.

Improve delivery quality

By validating recipients before sending, the platform improves overall delivery efficiency and helps maintain cleaner messaging traffic.

Reduce messaging costs

Detect fake, inactive, corrupted or landline numbers before SMS messages are sent. This helps eliminate unnecessary message delivery attempts and can reduce messaging costs by up to 40-50%.

Rapid deployment

Connect through standard SMPP or API interfaces without major system changes, so existing applications benefit from fraud protection with minimal implementation effort.
