The UPC and EAN barcodes have been in use since the 1970s to encode Global Trade Item Numbers (GTIN), which uniquely identify a product for retail checkout or tracking purposes. UPC, UCC, EAN, JAN, GTIN-8, GTIN-12 and GTIN-13, ISBN and Bookland barcodes are all created from the same symbology type, commonly known as the UPC/EAN barcode. GS1 DataBar (formerly RSS-14) is a smaller and more advanced barcode type that may be used in retail checkout systems after January 1, 2010.



SpecName (constant) The variable containing the input to be converted. Proper UPC font must be applied in the template.

ErrorMessage (multiple | optional) The error message to return when any error occurs.

Source Code

public static void EAN13(string SpecName, object ErrorMessage)
		string code = Actions.Variable(SpecName).Value;
		Actions.Variable(SpecName).Value = CallFontEncoder("EAN13", new object[] { code });
	catch (Exception ex)
		throw new Actions.Four51ActionsException(ex.Message, (string)ErrorMessage);
