Is there a way to tell the country something is made in from the bar code?

There is a rhyme and reason to bar codes.  In case you are interested in where a product originated, it might be in the bar code.  

The first 2-3 numbers indicate the location of the business headquarters associated with the product. Some of the time it accurately indicates where the product was made.  However, there are other times when the company's headquarters is not where the product originated.

For some examples: 

• 690, 691, 692...:  company in China (if you want to buy American or at least North American...)
• 471 company in Taiwan
• 00-08 company in USA
• 09 Canada
• 49 Japan
• 30-37 France
• 40-44 Germany
• 50... UK.
