There are 2 types of UPC codes you will see most often UPC-A and UPC-E:
UPC-A barcode is divided into four areas:
1) The number system,
2) The manufacturer code,
3) the product code, and
4) the check digit.
Normally the number system digit is printed just to the left of the barcode, the check digit just to the right of the barcode, and the manufacturer and product codes are printed just below the barcode. See Below
UPC-E barcodes were created to allow the use of UPC barcodes on smaller packages where a full 12-digit barcode may not fit, a 'zero-suppressed' version of UPC was developed called UPC-E, in which the number system digit and all trailing zeros in the manufacturer code and all leading zeros in the product code are suppressed (omitted).
My Pricebook stores all UPC codes as UPC-A codes. If you enter a UPC-E code, My Pricebook will automatically covert that to UPC-A code:
If you enter :0781140
My Pricebook will convert that to: 07800000114
When entering UPC codes, please enter the beginning digit and all digits except the very end digit. If you look at the diagram above you will always enter Number System digit and the middle digits. You almost never use the Check Digit however, depending how your register is set up, you may need to enter it..
