When shopping online, many customers accidentally enter incorrect shipping addresses during checkout. This leads to failed deliveries, increased costs for retailers due to reshipping, and frustration for buyers. Although some e-commerce platforms have built-in address validation, these tools are inconsistent and easy to ignore. A universal solution built directly into the browser could prevent these issues before they happen.
A lightweight browser extension could monitor and verify shipping addresses in real time as users enter them on any e-commerce site. Instead of relying on retailer-specific tools, the extension would:
Since it works client-side, no retailer integration is needed—making adoption seamless for both shoppers and businesses.
For consumers, fewer lost packages mean less hassle with customer service and refunds. Renters or frequent movers would especially benefit from avoiding outdated addresses. Retailers save on reshipping costs and reduce customer complaints. Delivery companies spend less time handling undeliverable packages.
A possible revenue model could include:
The simplest version could start with basic checks (like ZIP code validation) running locally in the browser to respect privacy. Over time, optional integrations with postal APIs (like USPS) could improve accuracy. Machine learning could adapt the tool to different checkout page designs without needing customization for each site.
Since existing tools like Google Autofill require direct website integration, a browser-native approach could fill the gap by working universally while keeping validation proactive and user-friendly.
