Which barcode Amazon asks for
When you create a listing, Amazon asks for a product ID: a UPC, EAN, JAN, ISBN or GTIN-14. Amazon checks that ID against GS1 data, so it has to come from a GS1 company prefix licensed to the brand on the product. Amazon's product ID rules spell this out.
- Selling your own brand: license a company prefix from GS1 US or the GS1 organization in your country, then number each variant.
- Reselling another brand: use the manufacturer's UPC or EAN from the packaging. Don't create a new one.
- No barcode on a product you make: brand owners can apply for a GTIN exemption in Seller Central instead.
- Cheap codes from resellers often belong to another company's prefix, and Amazon can remove listings whose code doesn't match GS1 data.
UPC, EAN or FNSKU label?
The UPC or EAN is the manufacturer barcode on your packaging, and it is what this generator draws. Fulfillment by Amazon adds a second code, the FNSKU, which identifies your offer in Amazon's warehouses. Print FNSKU labels from Seller Central when you create a shipment, so they have the layout Amazon expects.
| Code | What it identifies | Where it comes from |
|---|---|---|
| UPC (GTIN-12) | The product, for every seller | GS1 US or your GS1 organization; barcode from this generator |
| EAN (GTIN-13) | The product, for every seller | Your national GS1 organization; barcode from this generator |
| ASIN | Amazon's catalog page for the product | Assigned by Amazon when the product ID is new |
| FNSKU | Your units in Amazon's warehouses | Seller Central, as printable labels |
Get your Amazon barcodes in four steps
The barcode is the last step. The number behind it is what Amazon checks.
- License a GS1 company prefix in the country where your company is based.
- Give every variant its own GTIN: each size, color and pack size.
- Draw the barcode here as UPC-A or EAN-13 and put it on the packaging artwork, at 80% to 200% size with its quiet zones.
- Enter the same number as the product ID in your listing, and check the check digit first with the EAN and GTIN validator.
UPC or EAN on Amazon?
Amazon accepts both, in every marketplace. Use the one your GS1 organization issues: UPCs from GS1 US, EANs from GS1 Nederland, GS1 Germany and the other European organizations. A UPC with a 0 in front is the same number as an EAN-13, so don't list one product under both. The EAN-13 page and the UPC page cover the specs of each.
One barcode is easy. A catalog of GTINs needs checking.
WISEPIM's Quality Guard checks the GTIN on every product, blocks wrong check digits and flags missing and duplicate codes before Amazon, bol.com or Google reject them.

Frequently asked questions
Do I need a GS1 barcode to sell on Amazon?
In most categories, yes: Amazon asks for a UPC, EAN, JAN, ISBN or GTIN-14 and checks it against GS1 data. Brand owners whose products have no barcode can apply for a GTIN exemption instead.
Can I use this generator to make a UPC for Amazon?
You can make the barcode for a UPC you own. The generator does not issue numbers, so the UPC itself has to come from your GS1 company prefix.
Can I buy cheap UPC codes for Amazon?
Codes from resellers often belong to another company's GS1 prefix. Amazon compares product IDs with GS1 data and can remove listings that don't match, so license your own prefix from GS1.
Is the FNSKU the same as a UPC?
No. The UPC identifies the product for every seller. The FNSKU identifies your units in Amazon's fulfillment centers and comes from Seller Central as a label.
