Everything You Need to Validate Addresses
Address Guardian offers a comprehensive suite of address validation tools built specifically for Shopify merchants. From real-time checkout validation to bulk order processing, every feature is designed to eliminate failed deliveries and protect your bottom line.
Core Validation
The foundation of Address Guardian — catch address errors before they cost you money.
Thank You Page Validation
Validate shipping addresses on the order confirmation page and prompt customers to correct errors before it is too late. Address Guardian displays a clear, branded widget that highlights exactly what is wrong — missing apartment numbers, misspelled streets, or invalid postal codes — and lets the customer fix the issue in one click without contacting support.
Checkout Validation
PlusCatch address issues right at checkout so customers never complete an order with a bad address. By integrating directly into the Shopify checkout flow, Address Guardian validates the shipping address in real time and warns customers before they place their order — eliminating the most common source of failed deliveries.
Address Autocomplete
Speed up checkout with real-time address suggestions as customers type, reducing errors from the start. Powered by authoritative postal databases covering 250+ countries, autocomplete ensures customers select a verified, deliverable address every time — improving conversion rates and eliminating typos before they happen.
Order Management
Powerful tools to organize, filter, and act on address issues across your order pipeline.
Automatic Order Tagging
Orders with address issues are automatically tagged in Shopify so your team can review them at a glance. Tags are fully customizable — create separate tags for undeliverable addresses, PO Boxes, missing apartment numbers, and more. Filter your orders list instantly to prioritize which shipments need attention before they leave the warehouse.
Blocking Rules
Define custom rules to block or flag orders from PO Boxes, military addresses, or specific regions. Set up granular policies per country, state, or postal code range to enforce your shipping restrictions automatically. Blocking rules help prevent costly carrier surcharges and ensure every order you fulfill is actually deliverable.
Bulk Validation
Validate your entire order history in bulk to identify and fix address issues across past orders. Upload a CSV or run validation against your existing Shopify orders to uncover patterns — like repeat customers with bad addresses or regions with high error rates — and take corrective action before your next shipment batch.
Communication
Keep your team informed and verify customer contact details alongside their shipping address.
Email Notifications
Get notified instantly when a problematic address is detected so you can take action before shipping. Configure notifications per severity level — receive immediate alerts for undeliverable addresses, daily digests for minor issues, or route specific problems to different team members. Never let a bad address slip through unnoticed again.
Email Validation
Verify customer email addresses to reduce fraud and ensure you can always reach your buyers. Address Guardian checks for syntax errors, disposable email providers, and invalid domains in real time — helping you maintain a clean customer list, improve email deliverability, and catch potentially fraudulent orders before they ship.
Phone Validation
Validate customer phone numbers to ensure carriers can reach recipients for delivery coordination. Especially critical for international shipments where customs clearance and last-mile delivery often require a valid local phone number. Address Guardian verifies format, country code, and line type to prevent delivery failures at the door.
Integration & Customization
Seamlessly fits into your existing workflow and matches your brand — no coding required.
Express Checkout Support
Works seamlessly with Shop Pay, Apple Pay, Google Pay, and other accelerated checkout methods. Express checkout bypasses the traditional address form, which means errors can slip through more easily. Address Guardian hooks into the post-purchase flow to validate these orders and prompt corrections on the thank-you page.
Shopify Flow Integration
Trigger automated workflows based on validation results using native Shopify Flow connectors. Automatically hold orders with bad addresses, notify your warehouse team, send custom emails to customers, or update tags and notes — all without writing a single line of code. Build sophisticated fulfillment logic that responds to address quality in real time.
Widget Customization
Customize colors, text, and positioning of the validation widget to match your store's brand perfectly. Choose from multiple layout styles, adjust border radius and shadows, write your own copy, and preview changes live. Your customers will see a seamless, on-brand experience that feels like a natural part of your checkout.
Merchant Dashboard
A dedicated dashboard with analytics, validation history, and actionable insights on address quality. Track validation volumes, success rates, and cost savings over time. Drill into individual orders, export reports, and identify trends that help you optimize your shipping operations and reduce support overhead.
Residential/Commercial Detection
Identify whether an address is residential or commercial to optimize shipping rates and carrier selection. Carriers charge different rates for residential vs. commercial deliveries — and misclassification leads to unexpected surcharges. Address Guardian automatically detects the address type so you can select the right service level and quote accurate shipping costs.
