Driving a rental car in Mostar is straightforward when you use official lots, because the Old Bridge zone around Stari Most is pedestrian-only and city enforcement is active. JP “Mostar Parking” d.o.o. Mostar uses two on-street zones plus several official public lots, with rates published by JP “Mostar Parking” d.o.o. and updated through the city system rather than by informal attendants. Zone I is the most central and the most expensive, while Zone II covers a larger ring around Mostar Centar; for airport-style comparison, these are separate from OMO parking pickup logic and do not work like a pre-authorisation at a rental desk. For a short Old Bridge visit, the official 10 KM lots near Stari Most usually beat Zone I street parking by 50% on a 24-hour basis, and the weekday 17:00-19:00 free window at Katedrala and Federalna is useful for dinner plans in Stari Grad. If you miss payment, JP “Mostar Parking” d.o.o. issues a daily ticket plus a 10.00 KM administrative fee, so the cheapest option is usually to pay immediately rather than wait for a notice. For longer stays, foreign visitors can also buy the “Komercijalna” weekly pass for 45.00 KM, valid in Zone I and Zone II under the city tariff. The cheapest official tourist-grade option near Stari Most is usually one of the 10.00 KM daily lots: Katedrala, Federalna, or Ćiro. JP “Mostar Parking” d.o.o. lists these lots as camera-monitored public facilities, and the walk to the Old Bridge is typically 5-10 minutes depending on where you park and how busy Stari Grad is that day. That makes them a better value than the 20.00 KM Zone I street rate and a simpler choice than informal lots near the riverbank. Mostar visitors who want to combine parking with sightseeing can also use the lot-based approach for nearby Herzegovina day trips, including Blagaj Tekija, Počitelj, Kravice Waterfalls, and Međugorje. For route planning beyond the city center, driving the M17 is often easier than trying to thread a rental car through the Old Bridge core. Mostar parking charges depend on the season and the day of the week, and the city’s free periods are clearly defined by JP “Mostar Parking” d.o.o. and local reporting. In practice, this means paid parking is a weekday and Saturday issue, while Sundays and public holidays are free. Winter season, 1 November to 31 March: weekdays 07:00-18:00. Summer season, 1 April to 31 October: weekdays 07:00-21:00. Saturdays: 07:00-15:00 year-round. Sundays and public holidays: free. Free-parking windows do not override private parking rules, hotel rules, or enforcement notices from JP “Mostar Parking” d.o.o.; if a lot has a barrier, ticket machine, or cashier, always follow the posted tariff before leaving the car. These time windows matter if you are coming from OMO, SJJ, DBV, TZL, or BNX, because late arrivals can push you into a paid period even for a short stop near Stari Most. For cross-border visitors, keep a Green Card and third-party liability cover in the car, because Bosnia and Herzegovina enforcement checks can be strict at entries near Doljani and Bijača. Mostar’s payment methods are practical for visitors, and the city system supports SMS, app, and machine payment depending on the location and zone. The most useful detail for rental drivers is that the full license plate number must match the car exactly, including the official License Plate Subsystem format used on Bosnian registration records. SMS payment Zone I: send the license plate number to 0838801. Zone II: send the license plate number to 0838802. App payment GoParking lets drivers register a rental car, save a card, and extend paid time remotely. The app is useful for visitors planning time around Stari Most, the Stari Grad core, or a longer lunch stop in Mostar Centar. Cash or card Machines at public lots accept coins and cards. The JP “Mostar Parking” cashier’s office is at Bulevar narodne revolucije bb and typically operates Mon-Fri 07:00-15:30 and Sat 07:00-11:00. The best digital backup for city parking is the GoParking app, while the most useful planning app for EV drivers is PlugShare or Electromaps when they need a charger near a hotel or mall. Drivers who want fuel-price context before leaving Mostar can also check FMT FBiH oil info, especially if the next leg is toward Tarčin, Konjic, Jablanica, or the A1 motorway. Hotel and mall parking can be the most convenient choice if you are staying overnight, carrying luggage, or using an electric vehicle in Herzegovina.
