PCN for suspended bay parking in Private Land Parking Enforcement Posted March 2, 2012 Hang on! Code 16 is for permits, isn't it? This is a pay & display bay - so it should be code 06. Is it definitely C16 and not 06? Does the description next to the code say permits, or pay & display? Sorry my bad. Its contravention code 21 on the PCN slip. Pay and display bay as the ticket dispenser was just round the corner. I thought HYMN was refering to the first 3 letters of the PCN which was CL6.
