The SUBE Card: How to Get and Recharge Buenos Aires' Transport Card

What SUBE actually is, and why you cannot skip it

SUBE is the contactless card that pays for almost all everyday public transport in and around Buenos Aires. It is not an optional convenience the way a transit card can be in some cities — it is the only way to pay. The Subte underground, the colectivo buses that criss-cross the city, and the suburban trains that run out to places like Tigre and San Isidro all run on it. Turnstiles and driver-side card readers are built around SUBE and nothing else: there is no cash fallback, and foreign contactless bank cards are not accepted for ordinary rides.

This guide is deliberately narrow. It does not retell how the Subte network is laid out or how the colectivo routes work — that is covered in the dedicated Subte guide and colectivo guide. What follows is the administrative, practical side: where a visitor actually gets a SUBE card, how to load money onto it, what it costs, and the situations where the system is less convenient than a brochure would suggest.

Do you need one, and when to get it

If your visit includes more than a couple of taxi rides, get a SUBE card. It pays for the Subte, the buses, and the suburban trains, which together are the only realistic way to reach places like Tigre and the Paraná Delta or San Isidro without a private transfer. A short weekend spent mostly walking the Microcentro, San Telmo and Palermo on foot and by taxi could in principle get by without one, but as soon as a Subte ride or a bus out to Belgrano or Recoleta enters the plan, a card becomes necessary rather than convenient.

Get the card early. It is far less stressful to buy and load a SUBE card on your first afternoon than to discover on the way to catch a train that the nearest kiosk is out of stock.

Where to buy a SUBE card

There is no single official SUBE office chain to walk into; the card is sold through a network of outlets, and coverage is uneven.

• Subte station ticket booths. Most staffed stations on the six lines sell SUBE cards over the counter. This is the most reliable single option for a first-time visitor, because the staff handle SUBE transactions daily.
• Kiosks and shops displaying the SUBE logo. Many ordinary street kiosks across the city sell and recharge SUBE cards, marked with a small blue-and-white sticker. Coverage is dense in central, well-trafficked barrios like the Microcentro, Palermo and Recoleta, and thinner in quieter residential streets.
• Post offices (Correo Argentino). A number of post office branches issue and recharge SUBE cards as part of their regular counter services.

None of this is guaranteed at any single location. Kiosks run out of physical cards, especially at busy times or after a wave of tourist demand, and not every kiosk that sells snacks and drinks also handles SUBE — look for the sticker rather than assuming. If one kiosk near your accommodation doesn’t have cards in stock, the nearest Subte station is usually the most dependable fallback.

Do not assume the airport is a safe first stop for buying a card. Coverage at Ezeiza (EZE) and Aeroparque (AEP) is inconsistent, and arriving travellers are better off planning to buy a card once they reach the city — at a Subte station near their hotel, for instance — than counting on an airport kiosk having stock.

What it costs

SUBE separates two things: a small one-off fee to issue the physical card, and the travel credit you load onto it afterwards, which is spent down trip by trip. Both figures move with Argentina’s ongoing inflation, so this guide will not print a fixed peso amount — any number written here would likely be stale within weeks. Ask at the point of purchase what the current issuing fee is, and check a recent source (the official SUBE site, or your accommodation) before budgeting. Treat any price you see quoted anywhere, including on this site, as a dated snapshot rather than a fixed rule, and where useful convert to euros or US dollars at the live rate to get a feel for the real cost.

Item	What it is	Notes
Card issuing fee	One-off, paid once per physical card	Small; check the current amount at purchase
Travel credit	Prepaid balance spent per ride	Top up in whatever increment the outlet allows
Subte fare	Deducted per ride from the balance	Flat fare regardless of distance on the network
Colectivo fare	Deducted per ride, varies by distance travelled	Driver-side reader calculates the fare when you tap

How to recharge (top up) a SUBE card

Recharging uses the same network as buying the card in the first place:

1. Subte station ticket booths — hand over cash, state the amount, and the balance is added to your card immediately.
2. SUBE-branded kiosks — the same outlets that sell new cards will top up an existing one.
3. Post office counters — where the service is offered.
4. Recharge machines inside larger Subte stations — self-service terminals that accept cash for topping up, useful outside staffed ticket-booth hours or when the queue at the counter is long.
5. The SUBE app or website, for cards and payment methods that support online top-ups — this depends on having a compatible local payment method and is generally less practical for a short-term visitor than paying cash at a kiosk or station.

As with buying the card, recharging is not available at every single outlet at every hour — some kiosks close early, and recharge machines inside stations can occasionally be out of service. Build in a small buffer rather than recharging with your last few pesos of balance right before a trip.

A realistic first day with SUBE

• Arrive in the city and settle into your accommodation.
• On your first outing, look for the nearest Subte station or a kiosk with the SUBE sticker — do this before you specifically need to travel, not en route to catch a train.
• Buy the card, pay the small issuing fee, and load an initial amount of travel credit — enough for several days of Subte and colectivo rides, since running dry mid-trip on the Subte means being turned away at the turnstile.
• Keep the card somewhere you can reach quickly; both the Subte turnstiles and the colectivo driver-side readers expect a simple tap.
• Top up again whenever the balance gets low — most riders develop a habit of checking the balance shown on the reader each time they tap, and recharging a day or two before it would run out rather than right at the edge.

SUBE on the different networks

The same card, the same balance, three different transport modes:

• Subte. Tap at the turnstile on entry; the flat fare is deducted regardless of how far you travel or how many line changes you make within the system, as covered in the Subte guide.
• Colectivos. Tap on a reader mounted beside the driver when boarding; state (or the driver’s screen shows) the destination zone, and the fare, which varies with distance, is deducted on the spot. Full detail is in the colectivo guide.
• Suburban trains. Tap at station turnstiles, the same way as the Subte. This is the mode most visitors meet on the Mitre line to Tigre, which passes San Isidro on the way.

One notable exception: the Tren de la Costa, the light-rail line through the northern suburbs, is a separate, privately run tourist service with its own ticketing rather than a standard SUBE-fare commuter line — check current ticketing for that specific ride rather than assuming a SUBE tap covers it in exactly the same way as the Mitre line trains.

Common mistakes to avoid

• Assuming any kiosk will have cards in stock. Look for the SUBE sticker, and have a backup (the nearest Subte station) in mind rather than relying on a single guess.
• Trying to pay a colectivo driver with cash. It will not work; drivers only accept SUBE taps.
• Expecting a foreign contactless bank card to work at the turnstile. It won’t, unlike contactless-payment metro systems in some other cities — you need an actual SUBE card.
• Letting the balance run to zero before a Subte ride. Subte turnstiles are strict about insufficient balance and will simply block entry; colectivo drivers are generally more forgiving of a small shortfall, but it is not something to plan around.
• Buying only enough credit for a single trip. Queuing to recharge every day eats into sightseeing time; loading several days’ worth at once, within what you’re comfortable carrying, saves repeat stops.

Frequently asked questions about the SUBE card

Where do I buy a SUBE card in Buenos Aires?

At Subte station ticket booths, at kiosks and shops displaying the blue SUBE sticker, and at post offices (Correo Argentino) that offer the service. Not every kiosk sells them, and stock runs out, so it helps to have two or three options in mind rather than one.

Can I pay for the Subte or a colectivo with cash or a card instead?

No. The Subte, colectivo buses and suburban trains in Buenos Aires require a SUBE card; drivers and turnstiles do not accept cash fares, and foreign contactless bank cards are not accepted for everyday rides.

How much does a SUBE card cost and how much should I load onto it?

The card itself has a small one-off issuing fee, separate from the travel credit you load. Because prices and top-up rules change with inflation, treat any peso figure as a dated snapshot and check the current amount when you buy.

Where can I recharge (top up) a SUBE card?

At the same places that sell them — Subte ticket booths, SUBE-branded kiosks, post offices — plus dedicated recharge machines inside many larger Subte stations, and via the SUBE mobile app or website in some cases if the card supports it.

Can I use the same SUBE card for the Subte, the bus and the train?

Yes. One SUBE card works across the Subte, the colectivo bus network and the suburban trains that serve Greater Buenos Aires, including the line out to Tigre.

Is SUBE available at the airport?

Not reliably as a first stop. It is safer to plan on buying a card once you reach the city centre, at a Subte station or a kiosk near your accommodation, rather than assuming an airport kiosk will have one in stock.

Can several people share one SUBE card?

It is possible to tap the same card more than once for a group, but each cardholder loses the option of some personalised balance checks tied to their own card, and queuing to share one card at a busy turnstile is slower than each traveller carrying their own.

What happens if my SUBE card runs out of balance while I’m travelling?

A colectivo driver will generally still let a passenger with insufficient balance travel once into a small negative balance, which must be topped up before the next trip; Subte turnstiles are stricter and will simply refuse entry until the card is recharged.

Practical planning beyond SUBE

A SUBE card gets you moving, but it’s only one piece of a first visit. If you’re still working out the shape of your trip, the Subte guide and colectivo guide cover how the networks themselves are laid out, while a guided option like a half-day tour that gets you moving around the city by public transport with a local guide is a useful way to get comfortable with tapping in and out before doing it solo.

For a broader first look at the city’s layout and landmarks, a half-day city tour covering the main sights pairs well with a SUBE card you’ll then use independently for the rest of your stay. Shoppers heading between barrios often prefer a guided shopping outing that handles the logistics rather than juggling bus routes on day one, and travellers who’d rather skip public transport altogether for a specific outing can look at a guided motorcycle tour of the city as an alternative way to cover ground.

For budgeting the rest of your trip alongside transport costs, see the currency and budget guide, and for the airport side of the journey, the EZE vs Aeroparque comparison explains which airport you’re likely to land at and how far it is from where SUBE coverage begins.
