How we can help
Barcodes that look right and are wrong
After a store migration, the barcode field is often full of junk numbers that look real. Every product appears to have a barcode, and every one fails the check, which blocks Google Shopping and marketplaces.
Every barcode validated, junk removed and brand and MPN filled in where no real number exists.

Questions
A Global Trade Item Number, the number printed under a product's barcode. It comes in 8, 12, 13 and 14 digit forms. EAN-13 is the usual one in India, and UPC-A (12 digits) is the one used in the US and Canada.
The last digit. It is calculated from the others, so a mistyped or made-up number usually fails the check. This tool tells you the digit it should be.
The drawing will scan, but marketplaces and Google Shopping check the number against the GS1 registry. A number you invented will fail that check. Real numbers come from GS1 India.
890 is the GS1 prefix for India. Numbers issued to Indian companies usually start with it, but a product made elsewhere and sold here carries its own country's prefix.
Do not invent one. In Google Merchant Center you can mark the product as having no identifier and supply a brand and part number instead.
No. The check and the drawing happen in your browser. Nothing you enter is sent to us.
