Discover how FashionHub, a $45M Shopify Plus merchant, implemented real-time phone validation to reduce cart abandonment by 47%, increase delivery success rates by 93%, and recover $2.1M in annual revenue through automated customer recovery.
FashionHub, a fast-growing fashion retailer on Shopify Plus, was losing approximately $45,000 each month to cart abandonment and failed deliveries. Their core problems centered around invalid phone numbers collected during checkout.
32% cart abandonment rate - significantly above the 20% industry average for fashion e-commerce
18% delivery failure rate due to invalid or disconnected phone numbers
245 monthly customer support tickets related to delivery issues and order status inquiries
"We were hemorrhaging money every month due to invalid phone numbers. Our delivery partners would attempt to contact customers, fail to reach them, and return packages to our warehouse. The reverse logistics costs were eating into our margins, and we were losing customers to competitors who could actually deliver their orders."
FashionHub implemented a comprehensive phone validation system using Phone-Check.app API that validates phone numbers in real-time during checkout and automates customer recovery workflows.
Instant phone number validation as customers enter their details during checkout, preventing invalid numbers from entering the system.
Advanced detection of VoIP numbers, temporary phones, and high-risk carriers to prevent fraudulent orders and ensure legitimate customer communication.
Intelligent SMS workflows that automatically follow up with customers who abandon carts, offering personalized assistance and recovery incentives.
Pre-delivery verification ensures delivery partners can reach customers, dramatically reducing failed delivery attempts and reverse logistics costs.
The implementation was completed in 3 phases over 6 weeks, with minimal disruption to existing operations.
Custom Shopify checkout validation script integrated with Phone-Check.app API
// Shopify checkout phone validation
async function validateCheckoutPhone(phoneNumber) {
try {
const response = await fetch('/api/validate-phone', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'X-API-Key': process.env.PHONE_CHECK_API_KEY
},
body: JSON.stringify({
phone: phoneNumber,
country: 'US',
includeCarrier: true,
includeRisk: true
})
});
const result = await response.json();
if (!result.isValid) {
return {
valid: false,
message: 'Please enter a valid phone number'
};
}
if (result.isVoIP) {
return {
valid: false,
message: 'Mobile phone number required for delivery updates'
};
}
return { valid: true };
} catch (error) {
console.error('Phone validation failed:', error);
return { valid: false, message: 'Unable to validate phone number' };
}
}Shopify Flow workflow automation for pre-delivery verification
// Shopify Flow action for delivery verification
async function verifyDeliveryPhone(order) {
const phoneNumber = order.shippingAddress.phone;
const verification = await fetch('/api/phone-verify', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
'X-API-Key': process.env.PHONE_CHECK_API_KEY
},
body: JSON.stringify({
phone: phoneNumber,
realTimeCheck: true
})
});
const result = await verification.json();
// Add tag to order for internal tracking
if (result.isActive && !result.isDisconnected) {
await Shopify.order.update(order.id, {
tags: [...order.tags, 'phone-verified']
});
} else {
await Shopify.order.update(order.id, {
tags: [...order.tags, 'phone-verification-failed']
});
// Trigger customer service workflow
}
