Barcode and 2D Code Generators

These generators produce a linear barcode from the text or number you type. Pick the symbology your use needs, from UPC retail codes and Code 128 or Code 39 to GS1, ISBN, random test numbers and the USPS postal barcode. The Data Matrix (including GS1 DataMatrix), PDF417 and Aztec generators make two-dimensional codes that hold more data.
