'Barcode prefixes identify where a product was made'

Viral images on social media claim that barcode prefixes can identify where a particular product was made, Reuters reports. The prefixes encourage social media users to stop purchasing Chinese-made products and instead go with the Aerican alternatives. 'Pick up a product. Look at the barcode. If the first 3 numbers are 690 or 691 or 692, the product was made in China. Put it down and buy from any other country. If the numbers are 00 thru 09 to start, it’s USA made. Buy American.'
