GS1 DataBar Expanded M
• Specify a character string of 38 to 66 digits (numbers not including '*').
• The delimiter of the application identifier is separated by "()" (parenthesis). (Although printed
as HRI characters, they are not encoded.)
• FNC1 is automatically added if FNC1 is not present before application identifier (10) or (21).
• FNC1 is automatically added if FNC1 is not present at the end of the data following application
identifier (30).
• An error occurs if FNC1 is present at the end of the data following application identifier (10) or
(21) because FNC1 is not necessary.
• If the application identifier is (01), the 14th digit of the data section is made the check digit. If
the check digit is not correct, an error occurs.
(Different than the case of GS1-128 in that the check digit is not automatically calculated and
added due to '*' . )
• '*' is skipped.
• An error occurs if the data immediately following the character string { is not a 1.
• Specify special characters according to the following formats.
