The app stopped syncing after the last update and support took a week to reply. We lost orders during the outage and had to switch to a competitor.

About AddressGuard Address Validator
Add real-time, carrier-validated address verification to checkout - or replace Shopify’s Google Autocomplete with our Autocomplete. Our address validator validates against global and local carriers and uses AI Autocorrection to fix small errors (Rd→Road), prevent failed deliveries, and cut correction fees (many carriers charge $25+). Create rules to block PO Boxes or require apartment numbers. No code, install in 5 minutes.
