The amount of characters that can be contained within a barcode depends on the specific barcode type being used. That said, 1D barcodes can contain up to two dozen or so characters, while 2D barcodes can contain hundreds or thousands. However, it is important to remember that as the amount of information in the barcode increases, the bigger it will become. This is especially true of 1D barcodes because the information can only be read in a straight horizontal line.
