Walmart barcode lookup

A barcode reader scans a code and tells you what product it belongs to. That’s a different job from generating one, which is what this site does.

This site doesn’t scan or look up barcodes. A “barcode reader” or “lookup” tool uses your device’s camera to scan a printed code and match it against a product database, which requires camera access and a database, neither of which this site uses. If that’s what you’re after, your phone’s native camera app or a dedicated scanning app handles it; this page covers the generating side instead.

What does Walmart require for a product barcode?

A GTIN, usually a UPC-A, registered to your business through GS1. Like Amazon, Walmart Marketplace checks new listings against GS1’s database in many categories, and a number that isn’t properly registered to you is a common reason a listing gets rejected or removed after the fact. See do you need a GS1 number for the full picture.

Once you have a valid number, generate the barcode here

Enter your UPC-A number below and download it as SVG or PNG.

SVG stays sharp at any size and is what you want for printing. PNG is easier to drop into a spreadsheet or listing.

Everything runs in your browser. Nothing you type is sent anywhere.

A barcode generated on this page is not a registered GTIN. It encodes whatever number you enter into a valid, scannable symbol. It does not register that number to you. Selling through a retailer or listing on a marketplace under most categories requires a number issued to your business by GS1. See do you need a GS1 number before you print at scale.
