GS1 Data Matrix- Including GTIN
We are trying to add a GS1 data matrix 2D barcode to our labels. We want it to include our lot number, production date, expiration date, and GTIN. Our GTIN numbers are only 12 digits but Bartender says it must be 13. I know a check digit is added at the end but it doesn't count that. When we set it up as having only 12 digits, it doesn't scan right. Is there a way around this?
We tried setting it up as having a 13 digit minimum and having it pad a 0 at the beginning. We just don't want this to confuse customers. If this is the only solution, what would be the impact of the extra zero? Is a 13 digit GTIN standard which is why Bartender requires it?

If you incorporating a GTIN-12 into a GS1 symbol (AI 01 or 02) then the full string, per the spec of the symbology, needs to be 14 characters long and so for a GTIN-13 then this would include a leading zero whilst for a GTIN-12 this would be two zeros as per the below.

Our GTINs are only 12 numbers so Bartender is making us only put one extra zero and it is counting the check digit as the 14th I guess. Should that be right? And mostly what I am wondering is if it is standard to add the extra zeros because I don't want it to cause confusion? Or is there a way to select a GS1 data matrix in Bartender that only requires 12 digits?

It is the GS1 standard that GTIN AI's (01 and 02) must be 14 digits, the first character (or two characters if encoding a UPC-E number) will be a zero and the last digit will be a check digit. The check digit formula is the same for EAN and UPC as the GTIN AI's and BarTender will automatically calculate this so you may need to strip this from your data to let BarTender add it.
As you can see in the image below the UPC-E number I used was only 12 characters and BarTender added the 2 check digit to both the barcodes.
