Rectangular Data Matrix
The camera app can scan this. The Zebra app can scan this.
Besides squares, the Data Matrix standard defines a few rectangular sizes such as 8x18 or 16x48 modules. They let a 2D code fit onto narrow surfaces like cable sleeves or the edge of a circuit board.
Also called Data Matrix rectangle, rectangular DMC.

Where it is used
Narrow labels, cables, PCB edges, vials
People use it for narrow labels, cables, PCB edges, vials.
The camera app can scan this. The Zebra app can scan this. Both return the raw text.
Example
Datamatrix
Scan and create
Create this code opens the barcode generator with this symbology and the sample text filled in.
The camera app can scan this and shows it as Data Matrix. It returns the raw text. It does not open links, look up products, or start a payment. The desktop companion types that text into the focused field.
The Zebra app can scan this. It returns the raw text.
DMRE
DMRE adds more rectangular sizes to Data Matrix. The camera app can scan Data Matrix. This page does not claim those extra DMRE sizes.
DMRE – Data Matrix Rectangular Extension
DMRE extends classic Data Matrix with extra rectangular formats, such as 8x64 or 24x48 modules. These shapes carry more data in the same height, which helps on narrow labels and small parts.
Character set: As Data Matrix
Standard: ISO/IEC 21471
Example: ABC
