Ink spreads on paper, so bars print wider than drawn. Your printer can tell you how much; 0.02–0.05 mm is common for labels. Leave at 0 if unsure.

UPC Barcode Generator FAQ

Where do I get a UPC number?

From GS1 US (or your country’s GS1 office), which licenses a company prefix to you. Retailers and marketplaces check UPCs against GS1’s records, so made-up or resold numbers may be refused. Once you have your numbers, make the barcodes here for free.

What is the difference between UPC-A and UPC-E?

UPC-A is the standard 12-digit barcode. UPC-E is a shorter 8-digit version for small packs, made by leaving out zeros from certain UPC-A numbers; only numbers with those zeros can be shortened.

What size should a UPC barcode be?

At 100% a UPC-A is 37.29 × 25.93 mm (about 1.47 × 1.02 in), and it can be printed from 80% to 200%. Keep the blank margins on both sides, and don’t cut the bar height without your retailer’s OK.

How do I check my barcode scans?

Print it at 100% on the real label or packaging, then scan it with a barcode scanner or a phone app and check that the 12 digits match. Black bars on a white background scan best.

Is this UPC generator free?

Yes. No account, no watermark, no limits. The barcode is made in your browser and nothing is uploaded.
