San Francisco International Airport (SFO) ATMs and Currency Exchange: United States Airport Money Guide

This guide lists every ATM and currency exchange point we could confirm at San Francisco International Airport, sorted by terminal and by which side of security it sits on. Use the finder above to filter by terminal. Below, you will find how to get US dollar (USD) at the lowest cost, whether you are landing in San Francisco or only passing through SFO on a connection, and which screens and counters to say no to.

SFO has ATMs located throughout the airport, in every terminal both before and after security. Currency exchange at SFO is provided by Travelex, with desks in the International Terminal and near Gate 71 in Terminal 3. Where to find ATMs and Travelex currency exchange across SFO’s four terminals, which option gives the best rate, and how much US cash you need before you catch BART into the city.

Terminal financial overview

San Francisco International has three domestic terminals (1, 2 and 3) and an International Terminal with two halls (A and G), all linked by the free AirTrain. Cash is easy to get, but a US-dollar ATM withdrawal beats the exchange desks for most travellers. This guide shows where the machines and Travelex counters sit, how to keep fees low, and how to pay for BART and other transport into the city.

SFO has three domestic terminals (1, 2 and 3) and an International Terminal split into Boarding Areas A and G, all connected by the free AirTrain, which also links to BART, the rental-car centre and parking.

If you land from overseas you will come through the International Terminal, which has both ATMs and Travelex desks in the arrivals flow. For domestic flights and connections, every terminal has ATMs, and the free AirTrain makes it quick to reach the International Terminal or BART. If a Travelex desk is closed, the International Terminal keeps the widest service.

Across 4 terminals, this page lists 8 ATM locations (4 airside, 4 landside) and 2 exchange counter, kiosk or machines (1 airside, 1 landside). International Terminal (A and G) has the widest choice.

• International Terminal (A and G): Overseas flights. 2 ATM locations, 1 exchange point.
• Terminal 3: United domestic flights. 2 ATM locations, 1 exchange point.
• Terminal 1 (Harvey Milk): Domestic airlines. 2 ATM locations, 0 exchange points.
• Terminal 2: Domestic airlines. 2 ATM locations, 0 exchange points.

Inside vs. outside security strategy

For the best value, skip the exchange counter and withdraw US dollars from a bank ATM, choosing USD rather than your home currency. If you are connecting internationally and cannot leave airside, the ATMs inside security will cover you. If you have cleared customs, an arrivals-area ATM is quickest before the AirTrain and BART. Use Travelex only when you need another currency in a hurry or your card is not working.

As a rule at SFO: withdraw USD from a bank ATM landside when you arrive, buy only small amounts at a counter, and sell leftover US dollars back before security when you leave. Airside counters exist for convenience, not value, and once you are through passport control you cannot walk back out to compare.

Avoiding Dynamic Currency Conversion (DCC) markups

Dynamic Currency Conversion is the offer to charge a foreign card in its home currency instead of USD. It looks helpful because you see a familiar number, but the ATM or shop sets the exchange rate, and it is usually several percent worse than the rate Visa or Mastercard would apply. Airports are where most travellers meet it first.

Whenever an airport ATM or a card terminal offers to charge you in your home currency instead of US dollars, decline it and choose US dollars. That “convenience” option, called Dynamic Currency Conversion, lets the machine set its own exchange rate, which is typically 3–7% worse than the rate your own bank or card network would use. Paying in the local currency always routes the conversion through your card network (Visa, Mastercard), which is almost always cheaper.

1. At an ATM, when the screen asks to convert or offers a "guaranteed rate", choose decline or without conversion.
2. At a card terminal, if asked "USD or your currency?", pick USD. If staff choose for you, ask them to redo it.
3. Read the operator fee on the ATM screen before you confirm. If it is high, cancel and try another bank's machine.
4. Check your receipt: a printed exchange rate or the word "DCC" means a conversion was applied.

Local cash vs. card tips for San Francisco

You need very little cash in San Francisco. Cards and mobile wallets work for BART, taxis, ride-hailing and nearly everything else. Keep around $20–$40 in small bills for tips and the occasional cash-only purchase. Tipping is customary in the US — about 15–20% in restaurants, a dollar or two per bag for porters, and 15–20% for taxi drivers — so small denominations are the most useful.

Before you fly, check two things with your bank: the foreign transaction fee on card payments and the fee for overseas ATM withdrawals. A card that waives both makes paying in USD the cheapest way to spend in United States. Tell your bank you are travelling if it still asks, carry a backup card from a different network, and keep the airport counter for small top-ups only.

Prices and operators at airports change. We checked this page against the official SFO and operator listings on 20 October 2026; confirm hours on the airport's own map on the day you travel.
