Barcodes themselves do not hold information, they are simply a unique sequence of numbers encoded into an image represented by vertical black and white bars. The barcode number is simply used to quickly retrieve information stored a retailer's database. This unique number is assigned to your product and recorded in a retailer's sales/inventory system. Basically, the barcode is a unique number and has no informational value until the product is assigned manually via yourself or the retailer store. This is the same for barcodes purchased from any source (including GS1 India).
