Code 128 vs EAN Barcodes: Which Should Sellers Use?
Sellers meet two barcode families: Code 128, which can encode any SKU text, and EAN-13, the 13-digit retail barcode linked to registered GTINs.
Choosing the right one avoids confusion with marketplaces.
Code 128
- Encodes letters, numbers and symbols.
- Ideal for your own SKUs and warehouse labels.
- Used for Amazon FNSKU labels.
EAN-13
- 13 digits, issued through GS1 registration.
- Used as a product identifier (GTIN) on marketplaces that require it.
- Do not invent EAN numbers – use ones you are allowed to use.
Which one for which job
- Warehouse bins and stock counting – Code 128 with your SKU.
- Amazon FBA units – the FNSKU label (Code 128) from Seller Central or the FNSKU generator.
- Retail shelves and some marketplace listings – registered EAN/GTIN.
Keep barcodes scannable
Leave white space on both sides of the bars, print at 100% scale, and avoid very long SKUs that make the barcode too dense for small labels. Test one label with a phone scanner app before printing in bulk.
Getting EAN codes
If a marketplace asks for a GTIN, apply through GS1 India or use the codes provided by the brand owner. Some marketplaces allow an exemption for unbranded or private-label goods; check the current rules in your seller panel.
Printing either
Use the SKU & MRP sticker maker for SKU stickers. For EAN, print only codes you have registered or received from the brand owner.
