Q. Are there any stores where my bar codes will not work?

A. The bar codes may not be able to be used at either Wal-Mart or Kroger's. This is due to their application process and not to the actual functionality of the bar codes. In the application process for these 2 stores only, they require a copy of your GS1/UCC certificate with your own company's name on it. We cannot provide you a GS1 Certificate, however we provide your Our Certificate from GS1 as well as a certificate from us stating that you bought and own those numbers. Sending both in may or may not work.
