Amazon ASIN Checker is a lightweight, Manifest V3-compliant Chrome extension that lets Amazon sellers, sourcing VAs, and brand-protection teams instantly cross-check any product page: it reads the ASIN in the URL, compares it—locally and privacy-safely—to your read-only data source (Google Sheet via OAuth, uploaded CSV, or JSON/API), then overlays a color-coded badge (green = new, yellow = already sourced, red = restricted/do-not-buy) with hotkey copy, tooltip details, and optional batch scan for multiple tabs or pasted ASIN lists; it works on all global Amazon domains, saves hours of manual look-ups, prevents costly duplicate or restricted purchases, and accelerates VA training—while never collecting personal data or requiring Amazon credentials; full setup instructions, source code, and support are available at vaedistributions.com/asin-checker—Amazon and ASIN are trademarks of Amazon.com, Inc. and this tool is unaffiliated.
