Almost every form of public transport in Istanbul — metro, tram, bus, funicular, and even the city's commuter ferries — runs on a single rechargeable card called the Istanbulkart, and getting one is close to essential for a visitor rather than optional. Unlike some cities that now accept a foreign contactless bank card directly, Istanbul's system is still built around this one card, so buying one early in your trip saves a lot of friction later.
Getting an Istanbulkart
Istanbulkart machines are at every metro and tram station, most ferry terminals, and many bus stops, taking cash or card for both the card itself and the initial credit loaded onto it. The card has a small one-off purchase cost on top of whatever credit you load, and machines offer an English-language option, making the process straightforward even without any Turkish. Some kiosks and shops near stations also sell the card. It's worth buying one as soon as you arrive, ideally at the airport itself if you're taking public transport into the city.
Where it works
The Istanbulkart covers the metro (M1–M11 and growing), the T1 and other tram lines, the funiculars, city buses, and the Istanbul Şehir Hatları commuter ferries that cross the Bosphorus between the European and Asian sides — a crossing that's also one of the cheapest and most scenic short trips in the city. It's accepted on the Marmaray cross-Bosphorus rail tunnel too. Both of Istanbul's airports, the main Istanbul Airport (IST) on the European side and Sabiha Gökçen (SAW) on the Asian side, have Istanbulkart-compatible metro and bus links into the city, covered in more depth in our Istanbul airports to the city guide.
Topping up
Add credit at the same machines used to buy the card, with cash or a bank card, at metro and tram stations, major bus stops and ferry terminals across the city. There's also an Istanbulkart mobile app that lets you check your balance and, on supported phones, top up without finding a machine. Balances don't expire, so it's fine to keep loading more than you think you'll need rather than running short mid-journey and having to queue at a machine.
Transfers and discounts
Istanbulkart applies a discount on transfers between different modes within a set time window — moving from the metro to a bus, for instance, costs less than paying full fare twice, provided you tap within the window. The discount stacks for a few transfers, so a multi-leg journey across the city is often noticeably cheaper than several standalone fares would suggest. This system rewards using the card consistently for the length of your stay rather than switching between cash and card.
Fares and how they compare to a taxi
Istanbulkart fares are low by international standards, and even several transfers across the city in a day tend to cost a fraction of a single taxi ride. Given Istanbul's traffic, especially at peak times, the metro and tram are also often genuinely faster than a taxi or ride-hailing app across longer distances, particularly when crossing between the European and Asian sides where the Bosphorus bridges can back up badly. For a straightforward, budget-friendly way to see the city, leaning on the Istanbulkart rather than taxis is usually the better call on both counts.
The ferries: worth doing for their own sake
Istanbul's commuter ferries, covered by the same card, are one of the best-value sightseeing trips in the city — a short Bosphorus crossing between the European and Asian sides costs the same low fare as a bus ride, but delivers views of the skyline, the bridges and the strait that a taxi tunnel crossing can't match. If you have any spare time, it's worth taking a ferry purely for the ride rather than treating it as a pure means of transport.
Practical tips
- Buy your Istanbulkart on arrival, ideally at the airport, so you're not caught without one at your first station.
- Keep some cash on hand for topping up at machines that may not always accept foreign cards smoothly.
- Tap in and out consistently to make the most of transfer discounts, even on a short single-mode trip.
- The card works across both airports and the whole metropolitan area, including the Asian side, so one card serves your entire visit regardless of which side of the Bosphorus you're staying on.
If your trip continues overland from Istanbul, our intercity buses in Turkey guide covers how to travel onward once you're ready to leave the city, and our Schengen 90/180 guide is worth checking if you're heading on into the EU, since Turkey sits outside the Schengen area.
Frequently asked questions
Do I need an Istanbulkart, or can I use contactless payment?
You need an Istanbulkart for almost all Istanbul public transport — unlike some cities, foreign contactless bank cards aren't yet widely accepted directly on the network, so buying a card early in your visit is close to essential.
Can one Istanbulkart be used for a group?
Yes — a single card can be tapped multiple times for different people in the same group, drawing down the same shared balance, so you don't need to buy one per traveller.
Does the Istanbulkart work on the Bosphorus ferries?
Yes, the commuter ferries run by Istanbul's transport authority accept the Istanbulkart at the same low fares as buses and the metro, making a Bosphorus crossing both cheap and scenic.
Where can I buy and top up an Istanbulkart?
At machines in every metro and tram station, most ferry terminals, and many bus stops, plus some kiosks near stations. The Istanbulkart app also allows balance checks and top-ups on supported phones.
