With a clear idea about what type of information you are going to encode, the barcode selection will be much easier. This is also known as the barcode character set.

One main factor for choosing a barcode is based on what type of information you need to encode into it. Also, the 2D barcodes are relatively new barcode types and need support from more complex scanning devices. More often than not they support a bigger character set than 1D barcodes. In general, 2D barcodes can represent more data per unit area than 1D barcodes. They encode data generally in square or rectangular patterns of two dimensions.

2D barcodes -2D barcodes, or two-dimensional barcodes, are more complex.

They consist of vertical lines of varying widths with specific gaps resulting in a particular pattern.

1D barcodes -1D barcodes, or one-dimensional barcodes are linear barcodes.

There are many more barcode types than these 24 barcodes, but these 24 barcodes are pretty much the most popular ones. Collectively, they cover the bulk of application needs. In this article, we give you a comprehensive guide to 1D and 2D barcodes, covering 18 major barcodes types. With so many 1D and 2D barcode types, how do you choose the right one?
