AMZ Auto-ZipCode

AMZ Auto-ZipCode makes Amazon browsing accurate for sellers, shoppers, and researchers. Amazon often shows the wrong delivery ZIP/postal code — especially if you’re traveling or living abroad — which affects: • Prices • Delivery dates • Prime eligibility • Local availability • Buy Box behavior This extension fixes that automatically. What AMZ Auto-ZipCode Does • Automatically applies a ZIP/postal code every time you open an Amazon marketplace • Works on ALL Amazon retail domains (US, CA, UK, DE, FR, JP, IN, AU, SG, etc.) • Lets you choose a custom ZIP for each marketplace • Provides smart defaults based on major cities • For Amazon US, gives you a one-click toggle between two ZIP codes (e.g. California ↔ New York) Why It Matters As Amazon sellers, we often analyze listings across multiple marketplaces. Amazon detects your real location (or VPN), which can show skewed pricing and irrelevant availability. With AMZ Auto-ZipCode, you’ll always see: • Real price as a local shopper • Real delivery estimate • Real Buy Box state • Real availability and FBA vs. FBM behavior Privacy & Safety • No tracking • No analytics • No ads • No external requests • No data leaves your browser • 100% local, safe, minimal code AMZ Auto-ZipCode is built for sellers who want clean, accurate, consistent data across every marketplace.
