Tip · Product Catalog Cleanup and Cross-Store Check
Check barcode check digits before you upload
A tip for sellers on two stores: check the check digit on every GTIN before you upload a product file. A barcode with a wrong last digit can get a listing rejected, and it is easy to find in a spreadsheet before it is a problem.
The pilot

Product Catalog Cleanup and Cross-Store Check (pilot)
Our catalog cleanup pilot tests barcodes this way and lists the ones that fail, next to missing fields and price or stock differences between your stores. You apply the changes yourself. A person reviews the report before it reaches you.
Pilot. The sample is made from invented data.
