Frequently Asked Questions
- What barcode format do food products use?
- Most food products use EAN-13 (13-digit, global standard) or UPC-A (12-digit, North America). EAN-13 is recommended for most food sellers because it is accepted worldwide — including by US retailers and Amazon — while UPC-A is accepted only in North America. Both require a GS1-registered company prefix and product number if you are selling to retail stores; for internal tracking or DTC only, Code 128 with your own SKU system is sufficient.
- Do I need to register with GS1 to sell food products in stores?
- Yes, if you are selling to retail stores (supermarkets, convenience stores, online marketplaces like Amazon or Walmart). GS1 is the organization that issues official EAN-13 and UPC-A prefixes. In the US, GS1 US registration starts at around $250/year for a company prefix. Without a GS1-registered number, major retailers may reject your products. For farmers' markets, restaurant supply, or direct-to-consumer sales, GS1 registration is typically not required.
- Can I put multiple food products on one barcode label sheet?
- Yes. Bulk Barcode Generator generates one label per row in your CSV. Upload a list with one EAN-13 or UPC-A number per row, and the tool generates a PDF with one barcode label per product. You can then print onto Avery 5160 (30 labels per sheet) or Avery 5163 (10 labels per sheet, larger) using a standard laser or inkjet printer.
- What label size should I use for food packaging?
- For small food packages (bottles, jars, pouches): Avery 5160 labels (2⅝" × 1") fit most. For larger packaging or if you need the label to include extra text (ingredients, nutrition summary, contact info): Avery 5163 (4" × 2") gives more space. For high-volume production runs printed at a label print shop: export PNG at 300 DPI and specify 37.29mm × 26mm (EAN-13 at 100% magnification) to the printer.
- Can I generate food barcodes for both Amazon and supermarket sales?
- Yes. EAN-13 works for both — Amazon requires either UPC or EAN for most food listings, and supermarkets scan EAN-13 at checkout. Generate your EAN-13 list once, download the PDF for physical label printing, and enter the same 13-digit numbers into your Amazon Seller Central listing under the "External Product ID" field.
