I have:
GS1 DataMatrix barcodes are one of the most globally accepted standards in supply chain, healthcare and lots of other industries. It would be great if we could have an icon to represent it.
here's the link to GS1 DataMatrix guidline.

Include any example images so we know what the icon should look like.
So, it's like a QR code, but with a solid line on the left and bottom instead of the squares? Yeah, that seems worth adding.
datamatrix or data-matrix?
/edit wording
You almost got it right. Also the top and right of the square should be dotted dash lines. I created a sample for you.

About the name I personally prefer datamatrix so you could use the dash to separate actions from the icon base name. like datamatrix-scan or datamatrix-add.
It would be great if you could create a set of actions for it just like your QRCode icon.
By the way it is better that the scan icon be like the qrcode-scan with those 4 outer corners
Here's my attempt at creating a datamatrix icon. I also created a variant that uses normal cutouts instead of the cutouts that qrcode uses, not sure which one is better.
