Checkout address verification: catch undeliverable addresses

Carrier-validated address validation > prevent failed deliveries & cut carrier correction fees

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.

Block undeliverable addresses like PO Boxes, missing apt #s, and special chars
Hold undeliverable orders pre-3PL; add order tags to fit your workflows

Address Guard has saved us countless hours and prevented dozens of mis-deliveries. As a first-time ecommerce/shopify founder, we gradually learned the operational "gotchas" throughout 2024. One of the most painful was packing and paying for orders to ship to our customers, only to find them returned to us due to incorrect and/or invalid addresses, missing unit numbers, etc. Per usual, Shopify address validation feature set is severely lacking. This is where AG fills the gap at a reasonable price point.

Things we love:
-Post checkout address validation and nudges on Thank You page
-Email follow ups to customers who submit orders with potentially invalid or incomplete addresses prompting a confirmation or update
-(Optional) order fulfillment holds when invalid addresses are detected
-(Optional) order cancellations after X time when invalid addresses are detected
-Exhaustive list of address rules and options for validation
-Incredibly detailed log of address validation, customer contacts and updates, etc.
-(Optional) Email validation (occasionally we get customers providing us invalid emails, leaving us with no way to contact them for order or shipping issues)
-Fast, attentive support. They've literally gone and implemented feature request bug fixes within days, if not a couple of weeks.

Room for improvement:
-Occasional false positives for invalid addresses. Upon manual review and searching on Google Maps, we've been able to manually validate provided addresses and release orders. HARD problem to solve for. I'd rather error towards false positives than false negatives.
-Email reminders to customers to confirm or update their addresses seem a little hit or miss in terms of delivery/reception. Multiple customers have mentioned they never received them (spam?) and numerous times we've followed up manually with written email and get responses/updates.

The Address Guard Validator has been an absolute game-changer for our business, reducing a massive amount of returns due to incorrect addresses entered at checkout! Could not more strongly recommend this product, or the support team behind it. Insanely easy to use, beyond valuable.
