If you're reselling branded stock — wholesale, clearance, retail-arbitrage — you don't need to write every listing from scratch. The barcode already identifies the product. Look it up and you get the name, brand, category and a reference image in seconds.
What the numbers mean
- UPC — 12 digits, common in North America.
- EAN — 13 digits, the global/European standard.
- ISBN — books; it's an EAN under the hood.
They all live in the same product databases, so a lookup works the same way for each. The barcode is on the packaging, near the price or on the back.
Why look it up
- Speed — skip typing the exact product name and brand; the lookup fills them in.
- Accuracy — get the official name and spelling buyers actually search for.
- Category — a starting category for the marketplace, so you're not guessing.
- A reference image — confirm you've matched the right product before you list.
How to do it
- Find the barcode on the product or its box.
- Type the digits (or the number under the bars) into the lookup.
- Get the product name, brand, category and image back.
- Send it straight to the listing writer to draft a title, bullets and description.
When a barcode won't help
- Handmade, vintage or unbranded items often have no registered barcode — write those by hand.
- Bundles and multipacks you've assembled won't match a single code.
- Your own private-label products: register the barcode first, then it'll resolve.
Once you've identified the product, two tools finish the job: the AI Listing Writer drafts the copy, and eBay Comps tells you what to charge for it.
Database coverage is best for mainstream retail products; niche or regional items may not be found. Always confirm the result matches the item in your hand before listing.
