UPC-A, and its short form.
Make UPC-A and UPC-E barcodes for products sold in the US and Canada: the check digit, when a UPC-A can be made short as UPC-E, and the sizes GS1 allows.

In the US and Canada a till reads UPC-A: twelve digits, a GTIN-12 from GS1. Small packs carry UPC-E, the same number made short. The KeepSimp UPC barcode generator makes both and reads them back.
UPC-A.
Type the eleven digits of your number and the check digit is added, or all twelve and it is checked. Choose a size in millimetres to see it against GS1's range of 80% to 200%.
When a UPC-A can be UPC-E.
UPC-E leaves out a run of zeros, so only some numbers can be made short: those starting 0 or 1 with the zeros in the places the rules allow. Type a UPC-A number with UPC-E chosen and it is made short when it can be, or you are told it cannot. A scanner reads it back as the full UPC-A number.
Your own number.
The number must be one GS1 gave your company: tills look it up. KeepSimp draws the barcode, it cannot issue the number.
