While you may refer to the article Barcode Types and Functions for understanding the different types of Barcodes, I would like to share that out of all the mentioned types, Punchh uses EAN 13 barcode only.
A valid barcode is a 12-digit numeric code plus 1 parity digit added by the printer when printed as EAN-13 barcode. The 12-digit numeric code is generated by the POS using the structure and guidelines previously determined by Punchh.
