Can EAN 13 Symbols be scanned in USA/Canada?

A sunrise date on January 1, 2005 has been set for the global acceptance of GTIN-13. However, a few retailers in the US and Canada may experience a problem in that their systems not able to accommodate GTIN-13. In such case, the GTIN-12 represented in a UPC-A or UPC-E Symbol is required.

No. The GS1 System is a totally neutral system that can be used to identify anything that is traded among companies, as well as individual retail items at the point-of-sale.

The system is used by companies operating in all trade and industry sectors.
