PZN - bwipp/postscriptbarcode GitHub Wiki

PZN is a discrete, fixed length, self-checking barcode symbology used for pharmaceutical products in Germany.

Also known as: Pharmazentralnummer.

Variants:

• PZN7 is the seven-digit format.
• PZN8 is the eight-digit format.

• For the default PZN7 encoding, the data field must contain six digits or seven digits.
• The pzn8 option specifies that a PZN8 symbol is required, in which case the data field must contain seven digits or eight digits.
• The mandatory check digit is calculated automatically if not provided, otherwise the provided check digit is verified.
• Note: by definition, not all six-digit or seven-digit number sequences are valid inputs.
