Should we use the GS1 exemption for the 20 unit challenge?

What barcode should you use? You should get a GS1 Exemption for your 20 unit challenge.

Yes. We recommend using the GTIN exemption for your 20 unit challenge so that its cheaper. We also have found this works better for students so that there are less errors when making the listing.

This means you DO NOT need to purchase a UPC code from Gs1.
