How to Top Up Istanbulkart in 2026
If your Istanbulkart balance is running low, you can add credit at Biletmatik machines, official Istanbulkart top-up points or through Istanbulkart's digital services.
This guide explains both how to top up Istanbulkart and where to top it up while travelling around Istanbul.

How to Top Up Istanbulkart at a Biletmatik
For most tourists, a Biletmatik is the simplest way to add money to Istanbulkart.
Can You Top Up Istanbulkart with a Credit Card?
Yes, but the important detail is that not every Biletmatik is identical.
BELBIM states that its new-generation Biletmatik machines support credit card payments. Standard Biletmatik machines also support Istanbulkart TL-loading, but available payment methods can vary by machine.
Look for the bank card or contactless payment symbols before beginning the transaction.
Can You Top Up Istanbulkart with Cash?
Cash loading remains available through applicable Istanbulkart machines. The exact banknotes accepted can depend on the machine.
Follow the instructions displayed on the Biletmatik rather than relying on an old list of accepted banknote denominations.
How to Top Up Istanbulkart with the Mobile App
Istanbulkart also has an official mobile application. BELBIM allows users to add TL through Istanbulkart Mobil without visiting a physical loading point.
Depending on the transaction and card type, an online loading instruction may need to be transferred to the physical card by touching it to an appropriate Istanbulkart device or an NFC-enabled phone.
For short-term tourists, using a Biletmatik is often simpler than creating and configuring an Istanbulkart digital account.
Can You Top Up Istanbulkart Online?
Yes. Istanbulkart provides official online and mobile channels for adding balance.
If you use an online loading service, use only official Istanbulkart channels or authorized financial services.
How Much Should Tourists Add to Istanbulkart?
There is no single correct amount because it depends on how often you plan to use public transportation.
It is usually better for short-term visitors to add smaller amounts and top up again when necessary rather than leaving a large unused balance on the card at the end of the trip.
Current transport fares are covered in our main Istanbulkart 2026 guide .
How to Check Your Istanbulkart Balance
You can check your balance when using a Biletmatik or through compatible Istanbulkart digital services.
The remaining balance may also appear on transport readers after you tap the card.
What If the Top Up Does Not Work?
If the machine cannot read the card or the transaction fails, try another official Biletmatik before assuming that the card is damaged.
