Description

Global carrier-validated address validator > 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.

Global address verification (240+ countries) + multi-language (17+ languages)
Block undeliverable addresses like PO Boxes, missing apt #s, and special chars
Hold undeliverable orders pre-3PL; add order tags to fit your workflows
Built-in email & phone verification to improve data quality and delivery
Works with express checkouts: Shop Pay, Apple Pay, Google Pay, PayPal

Pros

Verify, standardize, cleanse, and format addresses for over 240 countries
Supports multi-language functionality, accommodating 9 languages across customer touchpoints
AI rules engine prevents shipments to over 15 different problematic address types such as PO Boxes, non-contiguous US states, and military addresses
Allows creation of custom checkout rules to prevent special characters before order completion
Prompts customers to correct addresses when issues are detected, offering real-time suggestions
Creates rules to ensure undeliverable addresses (PO Boxes, missing house numbers, etc) are flagged
Automatically holds orders that identify as undeliverable before they are sent to a 3PL (third-party logistics)
Tags orders with address status and applicable rules automatically
Customization options for address prompts and email notifications to match brand aesthetics

Cons

May require additional setup and configuration to fully customize and integrate with existing systems
Dependence on accurate initial data input; errors in entered address data might still require manual correction
Potential limitations in handling complex or non-standard international addresses despite broad country coverage
Relies heavily on the AI rules engine which may not be 100% accurate in all scenarios

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.

Excellent support. Only using the app for a few days but it looks to be pretty comprehensive in terms of what I require. Helpful to know that support is there if I need it.

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.

Very helpful app! Been able to help minimise orders going out with incorrect addresses as well as help reduce amount of return to sender parcels returned. Ryan has also been fabulous, direct communication and able to outsource information from carriers themselves. Highly recommend.

Ryan was incredibly helpful throughout our communication. He took the time to thoroughly explain the features and limitations of the service and was very responsive to all my questions. I really appreciated his efforts and excellent customer support.

Address Guard is an exceptionally well-developed and thoughtfully designed app, clearly built with customer input and feedback in their ethos. It is evident that the team has considered every aspect to meet user needs as its highly customisable. For businesses with specific niches, the team is highly receptive to feedback and willing to implement changes to accommodate unique requirements. The customer service experience has been outstanding, offering direct communication with team members who are efficient and proactive in addressing concerns. They would come highly recommended from me.

Does exactly what I need. We were having issues with non-latin characters at checkout, incorrectly auto-filled addresses, and then customers who didn't realize this until it was too late, their package was shipped. All better now.

We’ve been using this app to address a persistent issue with invalid customer inputs, and it has been a game-changer. As a business utilizing a 3PL, we often encounter orders flagged with “action required” due to invalid addresses. Resolving these manually was tedious and inefficient. This app has streamlined the entire process, saving us time and hassle. On top of that, their support team is outstanding—responsive, knowledgeable, and always willing to go the extra mile. Highly recommend for any business looking to optimize their order flow and reduce manual intervention!
