The "Barcode is not a Valid GTIN" error that sellers encounter when validating their barcode in MConnect is usually encountered when there are discrepancies in barcode validity, often related to incorrect check digits or missing numbers.
When a product's barcode fails to meet GTIN specifications, Marketplacer's validation system flags it as invalid. For instance, in the GTIN-13 format, each barcode must adhere to specific check digit criteria. Any deviation from these standards results in the generation of an error message.
