Some services that cross the boundaries between Buenos Aires City and the Buenos Aires Province — known as “national services” — have also adopted the new payment systems. If you’re planning a trip using any of the seven lines, you will need a SUBE card to get on board. These can usually be found at subway and train stations and community centers around Greater Buenos Aires. SUBE cards need to be registered, otherwise you’ll have to pay higher fares on all trips. As of December 1, 2025, the minimum fares for registered SUBE cards are AR$593,52 for Buenos Aires City buses, AR$658,44 for Buenos Aires Provincial buses, AR$494,83 for national services, AR$1.206 for the subway and AR$280 for trains.
