UPC & EAN Barcode Generator
Create scannable UPC-A and EAN-13 barcodes for product listings. The check digit is calculated for you — download as PNG or SVG.
UPC vs EAN — which do I need?
UPC-A (12 digits) is standard in the US & Canada.
EAN-13 (13 digits) is used in Europe and most of the rest of the world.
Amazon requires a GTIN (UPC/EAN) for most new listings. Enter your digits without the check digit and we'll compute it; or paste the full code to verify it.
How product barcodes work
A UPC-A (12 digits) or EAN-13 (13 digits) barcode encodes a number plus a final check digit that scanners use to confirm the read is valid. This tool computes that check digit for you, or verifies it if you paste a full code, then renders a clean, scannable barcode you can download as PNG or SVG.
Marketplaces like Amazon ask for a GTIN (UPC, EAN, or ISBN) on most new listings so each product maps to a single global identifier. The barcode image itself is just a visual encoding of that number — what matters for compliance is that the number is a real, registered GTIN.
Use the PNG for print-ready labels and packaging, or the SVG when you need a crisp, resolution-independent version for a design file.
Frequently asked questions
Do I need a barcode to sell on Amazon?
Most new Amazon listings require a GTIN such as a UPC or EAN, unless you have a brand registry exemption (GTIN exemption). The number identifies your product across the catalog.
Does this tool give me a registered UPC I can sell with?
No. It generates a valid, scannable barcode image from a number you provide, but it does not register a GTIN. To own a unique, brand-linked GTIN you buy it from GS1, the official issuing organization. Use this tool to visualize, verify, or print a code you already own.
What is the difference between UPC-A and EAN-13?
UPC-A is the 12-digit standard used mainly in the US and Canada. EAN-13 is the 13-digit version used in Europe and most of the world. They use the same underlying barcode symbology and check-digit math.
What is the check digit?
It is the final digit, calculated from the others, that lets a scanner detect mis-reads. Enter your data digits and the tool adds it automatically; paste a full code and it verifies the digit is correct.
Is it free and private?
Yes. It is completely free with no signup, and the barcode is generated entirely in your browser — nothing you type is sent to a server.
