Istanbulkart: how it works and why you need one

The Istanbulkart (İstanbulkart) is Istanbul’s unified public transport card. It works across the entire network: metro, tram, bus, ferry, funicular, and the Marmaray train under the Bosphorus. Without it, you pay a higher per-journey fare using tokens or paper tickets. With it, you pay less per journey, can transfer between modes with a reduced fare within 90 minutes, and move through the system quickly. Getting one is one of the first things to do on arrival.

What the Istanbulkart covers

Metro lines (M1–M11 and growing)
Tram lines (T1 through Sultanahmet, F1, F2 funiculars)
City buses (IETT)
Şehir Hatları ferries (Bosphorus ferries, Princes’ Islands ferry, Golden Horn ferry)
Marmaray (cross-Bosphorus underground train)
Teleferik (cable car lines)
Nostalgic tram on İstiklal Avenue

Not included: private taxis, IDO fast ferries (these have their own system), tourist-marketed sightseeing cruises.

How much does it cost?

As of mid-2025, the card itself costs approximately 70 TRY (deposit + card fee — verify current price, it changes). The card is not refundable when you leave (the TRY amount on it can be used until the last moment, but the card itself has no cash refund value). You load credit onto the card at machines.

A single journey costs approximately 10–13 TRY (under 0.50 USD at mid-2025 rates). Single tokens or paper tickets cost more and do not give transfer discounts.

The transfer discount: if you make a second journey within 90 minutes of the first tap-in, the second fare is reduced. A third journey within the 90-minute window costs even less. For a day of intensive public transport (metro + tram + ferry + metro), your total might be 50–80 TRY — less than 3 USD.

Where to get an Istanbulkart

Metro station vending machines: Available at all metro stations. English-language interface available. You can buy the card and load credit in one transaction.

Ferry terminals and tram stops: Available at Eminönü, Kabataş, and major stops.

Kiosks and shops: Blue or green kiosks labelled “Istanbulkart” near major transport hubs sell and top up the card.

Arrive at Istanbul Airport? The M11 metro machines have the card available before you even exit the terminal.

How to top up

Vending machines at all metro stations, ferry terminals, and major bus stops accept both cash (TRY) and card for top-up. The interface is available in English. Put in the amount you want to add; hold the card against the reader; done.

Minimum useful top-up for a 3–5 day trip: 200–300 TRY (approximately 6–9 USD). You will use it for every journey.

The key routes tourists use most

T1 tram: Runs from Bağcılar through Sultanahmet (Sultanahmet stop, Gülhane stop), continues to Eminönü, Karaköy, across the Galata Bridge, and terminates at Kabataş (ferry pier to Üsküdar and the Princes’ Islands). This is the core tourist route.

M11 metro: Istanbul Airport (IST) to Gayrettepe and city centre. The airport transfer line.

M2 metro: Vezneciler to Taksim and beyond. Connects to M11.

Marmaray: Sirkeci (near Sultanahmet) under the Bosphorus to Üsküdar and the Asian side. A legitimate two-continent transport option.

Şehir Hatları ferries: From Eminönü to Kadıköy, Üsküdar, Beşiktaş (seasonal), Bosphorus upper reaches. All covered by Istanbulkart.

Common mistakes

Buying single tokens: Unless you are making only one or two trips in Istanbul, the token system is less efficient. The Istanbulkart deposit is recovered in savings within 3–4 journeys.

Tapping on and forgetting: The transfer discount starts from your first tap. If you tap in but then wait at a station or board the wrong line, the clock is running. Be decisive.

Not loading enough credit: Running out of credit at a turnstile is avoidable. Load more than you think you need.

IST airport specifics: The M11 has its own fare structure — the airport-to-city journey costs more than standard city journeys. Have sufficient credit for the approximately 50–60 TRY fare.

Ferry tickets separately?

The IDO (Istanbul Sea Buses / Deniz Otobüsleri) fast ferries — which operate to Yalova, Bandırma, Mudanya (for Bursa) — are not covered by the standard Istanbulkart. They have their own ticketing (IDO app, kiosks). If you are taking the fast ferry to Bursa, buy an IDO ticket separately.

The standard Şehir Hatları slower ferries (Eminönü–Kadıköy, Eminönü–Üsküdar, Karaköy–Üsküdar, Princes’ Islands) are covered by Istanbulkart.

For the Princes’ Islands by ferry: see Princes’ Islands day trip guide.

Frequently asked questions about the Istanbulkart

No — each person needs their own card. You cannot tap the same card twice in quick succession for two passengers.

What happens to unused credit when I leave Istanbul?

The card and remaining credit have no cash refund value. Use whatever remains before your last journey. If you have a few hundred lira remaining and are buying food at a convenience store, note that some IETT kiosks and cafés at transport hubs accept the card for small purchases.

Do I need to register the card?

Not required for basic use. You can register it online for loss protection (if you lose the card, a registered card’s credit can be transferred to a new one). Registration at imo.iett.istanbul; optional for tourists.

Is there a day pass option?

Istanbul has offered limited single-day and multi-day travel cards, but the standard Istanbulkart is the most widely available and practical option. Check current daily/weekly pass availability on the IETT website closer to your travel dates.

Does the ferry to the Princes’ Islands use the Istanbulkart?

Yes — the public Şehir Hatları ferry from Eminönü or Kabataş to Büyükada (the largest Princes’ Island) uses the Istanbulkart. The journey to Büyükada takes approximately 60–90 minutes and costs a standard Istanbulkart fare.
