You can register a SUBE card online at argentina.gob.ar/sube, by phone, in person at a SUBE service center, or in the official SUBE app. Buy the card first, then register it with your name and ID. Registration is free, and it unlocks cheaper fares and balance protection if you lose the card.
This guide shows you what to prepare, how to register step by step, and how to load and use the card without wasting money or time.
What Is a SUBE Card and Do Tourists Need One?
SUBE is Argentina’s contactless transit card. It pays for buses (colectivos), the Subte (Buenos Aires metro), and suburban trains across the Buenos Aires metropolitan area. Most buses accept only SUBE. They do not take cash.
You need one if you plan to ride more than once or twice. Taxis and rideshares work without it, but public transport is far cheaper.
- Buses: SUBE is the standard payment method.
- Subte and trains: You tap in at the turnstile.
- Other cities: Many Argentine cities use SUBE too, though coverage varies.
Tip: Walking tours and short stays may not justify a card. If you ride three or more times a day, buy one.
Why Registering Matters
A registered card usually costs less per trip, can receive eligible discounts, and lets you recover your balance if you lose it. Unregistered cards work, but they often cost more. Check current fares on the official SUBE site.
What You Need Before You Register
Gather these items first:
- A physical SUBE card (or the digital version, if your phone supports it)
- The card number printed on the card
- Your passport or national ID
- An email address and a phone number
- A device with internet access
Warning: Rules for foreign visitors can differ from those for residents. If the online form rejects your passport details, call the official line or visit a service center. Verify requirements on the official SUBE channel before you travel.
How to Buy a SUBE Card as a Tourist
You have several options:
- Official SUBE channels: The government site lets you order a card for delivery or pickup. This works best if you plan ahead, but delivery takes time.
- SUBE service centers: Staff sell cards and help with registration on the spot.
- Kiosks and authorized shops: Look for the SUBE logo. Many kiosks (kioscos) sell cards.
- Airport and station points: Some airports and large stations have sales points.
Card prices change. Check the current price on the official site rather than trusting an old blog post.
Tip: Buy from a place that displays the SUBE logo. Avoid street sellers with no signage.
How to Register Your SUBE Card Step by Step
Registering takes about five minutes online. Many visitors look up sube registrar steps before they land, and the online route is the easiest one to finish from your hotel room.
Step 1 – Open the Official Site
Go to argentina.gob.ar/sube and look for the registration option. Check that the address starts with https and ends in .gob.ar.
Step 2 – Enter Your Card Number
Type the card number exactly as printed. Do not guess a digit.
Step 3 – Add Your Personal Details
Enter your name, document number, email and phone. Use the same spelling as your passport.
Step 4 – Confirm and Save
Submit the form. Keep the confirmation email or a screenshot. You may need it if the card has a problem later.

Other Ways to Register
Call 0800-777-7823, visit a SUBE service center with your ID, or use the official app on a supported phone.
How to Load Balance on Your SUBE Card
An empty card does nothing, so load it before you ride. You can load money in several ways:
- Kiosks and shops: Pay cash at stores that show the SUBE logo.
- Subway and train stations: Some stations have ticket offices or machines.
- The SUBE app: Pay with a debit card or digital wallet, where available.
- Digital wallets: Some bank apps let you top up.
Remember that loads from an app or website do not reach the chip right away. The card must touch a terminal or an NFC phone to finish the load. Tap your card on a reader or a phone before you board.
There is a maximum balance you can hold, and the system allows a small negative balance for one final trip. Both limits change with fare updates, so check the official figures.
How to Use SUBE on Buses, the Subte and Trains
On a Bus
- Tell the driver your destination or stop. Some routes charge by distance.
- Tap the card on the reader.
- Wait for the beep and check the balance on the screen.
On the Subte
- Tap at the turnstile.
- Walk through.
- You pay a flat fare per ride.
Tip: Buses do not accept cash, so keep your balance above what you need for the day. Spend any leftover before you fly home.
