There are four parking zones in Zagreb, indicated by signs on the side of the street: zone 1 is 1,60 Eur / h with a maximum waiting time of 2 hours, zone 2 is 0,70 Eur / h with a maximum waiting time of 3 hours, zone 3 is 0,30 Eur / h and zone 4 is 1,30 Eur/day. Purchase your ticket at the ticket machine box which is beside the parking sign and make sure you display it on your dashboard, or use your mobile to text message your registration number (no gaps) to the number shown (including the international code if you're using a foreign mobile). Your payment is confirmed when you receive a return text message from the appropriate authorities. As a timely service, you'll receive a text message reminding you to top up your parking ticket limit before it expires or to move your car. In case you don't pay for your parking spot or over-run your allotted time, you’ll be left a ticket valid for 24 hours from the moment the beady-eyed inspector spotted your naughtiness. The 24-hour ticket costs  13,30 , 8,00, 2,70 or 4,00 Eur respectively according to the zone, and can be paid in any post office or on  m-parking, ZgPark via Aircash, bmove, KEKS Pay.
