The global retail standard — found on virtually every product in stores outside North America. Requires 12 digits; check digit is auto-calculated.
UPC-A

The North American retail standard with 12 digits. Required by major US retailers including Walmart, Target, and Amazon FBA.
Code 39

Frequently Asked Questions
Which barcode format should I use for my product?+
For retail products sold globally, use EAN-13. For US/Canada-only retail, use UPC-A. For internal inventory, shipping labels, or custom applications, Code128 is the most flexible choice.
How do I get a barcode for my product to sell on Amazon?+
Amazon requires a GTIN (Global Trade Item Number), typically as a UPC or EAN. You need to purchase a GS1 company prefix from GS1 (gs1.org) to get official retail barcodes. SafeKit generates the barcode image once you have your number.
Can I generate a barcode without a watermark?+
Yes. SafeKit generates clean, professional barcodes with no watermark. Download as PNG for digital use or SVG for print and professional applications.
What size should my barcode be for printing?+
The minimum size for reliable scanning is 1 inch (25mm) wide. Download as SVG for infinitely scalable, print-ready barcodes. For standard retail, EAN-13 barcodes should be 37.29mm × 26.26mm at 100% magnification.
Is the barcode data kept private?+
Yes. All barcode generation runs entirely in your browser. No barcode data, product information, or files are sent to any server.
