As indicated in the Snopes article, it is pretty reliable though. I started looking at bar codes and calling various manufacturers to find out if their products were manufactured in China, as indicated by the bar code, or in America as indicated on their address on the label. Most reluctantly admitted that their products were made in China. Apparently they will indicate on the product "Made in the USA" if it actually is of course. Some said they have to by law if it is made in the USA. I don't know if that is true or not. Everyone I called, nearly 35 products, admitted that the bar code system is very reliable. Now the hard part, try and find something that says "Made in the USA".
