Barcode numbers can sort of give an indication.

The first three digits are determined by the country the barcode was assigned in. The barcode can’t tell you the country of origin of the product, but it’s fairly likely the company that made the product is headquartered in the country indicated by the code (or at least has some administrative presence there).

Here’s a list of country codes for reference: www.barcodestalk.com/…/barcode-country-codes
