The Tic code of Lottomatica, or the code necessary for the recognition and tracking of the operation carried out, can be found on the receipt of the operation itself and is necessary in the event of any subsequent request or clarification that requires a direct and unequivocal reference to operation in question. This applies a lot for the digital receipts that are received for operations carried out online and for the paper ones that are received for the operations instead carried out in the receiver.
