Planning a trip to the US from the UK? Whether you’re holidaying, working, studying, or visiting family there, you’ll need to work out the best way to spend in US dollars during your trip. If you have an American Express credit card, this could be a good option – especially as it’s a US-based company. But how do Amex cards issued in the UK work over in the States? This guide will provide all the essential information you need about using a UK Amex in the US. We’ll look at where Amex is accepted, the fees and exchange rates you can expect, and offer some practical tips to help you get the most from your travel spending. We’ll also introduce a popular alternative for international spending.

Can I Use My UK Amex in the US?
Yes, you can absolutely use your American Express card in the US. It is widely accepted across the country, at the majority of places that accept credit cards. This includes a vast array of establishments: * Supermarkets and large retailers: Think stores like Walmart, Target, Macy’s, Bloomingdales, Whole Foods, and Trader Joe’s. These major players typically welcome Amex. * Restaurant chains: From fast food giants like McDonald’s and Taco Bell to casual dining spots like Wendy’s and Starbucks, Amex is commonly accepted. * Gas stations: Major fuel providers such as Shell, Exxon, BP, and Mobil generally accept Amex. Furthermore, you can often use Amex to pay for public transport in many major cities, including New York City. However, it’s important to be aware that smaller businesses may not accept Amex. This is often due to the higher payment processing costs associated with Amex compared to other card networks like Visa and Mastercard. Therefore, it’s always wise to have a backup card or some cash on hand, especially if you plan to shop in smaller, independent local stores.
Amex Fees, Exchange Rates & Currency Conversion in the US
Even though American Express is a US brand, there are still fees to consider when using a UK-issued Amex card in the United States. This is because your credit card account is denominated in British Pounds (GBP), while your spending will be in US Dollars (USD). Similar to many other credit cards, Amex charges non-sterling transaction fees for spending in foreign currencies. They also levy charges for overseas cash withdrawals. Let’s break down what you can expect to pay: Table: Amex Fees for UK Cardholders in the US
| Transaction Type | Amex Fee |
|---|---|
| Foreign Currency Purchases | 2.99% currency conversion fee |
| Overseas ATM Withdrawals | 3% or £3 (whichever is greater) + 2.99% conversion fee |
It’s also crucial to remember that when you use a credit card to withdraw cash, interest may start accruing immediately, irrespective of any interest-free period you might have on purchases. This can significantly increase the cost of cash withdrawals.
Exchange Rates Used by Amex
American Express utilises its own exchange rate when converting currency between GBP and USD, referred to as the American Express Exchange Rate. You may be able to check this rate before making a purchase by looking in the American Express app or by signing into your online account and using their Foreign Transaction Calculator.
Dynamic Currency Conversion (DCC)
When you use your Amex credit card at a store or ATM overseas, you might be presented with a choice: to have the transaction processed in your home currency (GBP) or the local currency (USD). This service is known as Dynamic Currency Conversion (DCC). While DCC might seem convenient, especially if you’re unfamiliar with the foreign currency, it often comes at a hidden cost. DCC allows the vendor, payment processor, or ATM operator to set their own exchange rate, which is frequently marked up significantly above the mid-market exchange rate. Essentially, you're paying an extra fee for this perceived convenience. The golden rule here is to always choose to carry out transactions in the local currency (USD). By doing so, you ensure that American Express’s own exchange rate is applied, which is generally more favourable than the rate offered through DCC.

How to Minimise Fees When Using Your Amex in the US
Nobody wants to spend more than necessary while travelling. To help you minimise fees and save money when using your Amex in the US, consider these practical tips: * Avoid Cash Withdrawals: Unless absolutely necessary, try to avoid withdrawing cash using your credit card. The fees associated with overseas ATM withdrawals on Amex cards are quite high, and as mentioned, interest can start accruing immediately. * Use Fee-Free ATMs: If possible, seek out ATMs that do not charge their own fees. Otherwise, you’ll find an additional ATM operator fee added on top of the American Express charges. * Always Pay in Local Currency: This is a recurring but vital piece of advice. Paying in USD ensures you get a better exchange rate and helps you avoid expensive hidden fees associated with DCC. * Consider Alternative Travel Cards: Given that Amex can sometimes be more expensive for overseas spending and cash withdrawals, it can be sensible to explore alternative travel-friendly cards. These can serve as excellent backup options or primary spending tools. For instance, a card like the Wise card is specifically designed for overseas travel. It allows you to spend in over 150 countries with low fees and at mid-market exchange rates. You can also make up to two withdrawals of up to £200 each month for free per account. Beyond that, there's a small charge per withdrawal, and a percentage fee on amounts withdrawn above £200.
Tips for Using Your Amex Card in the US
To maximise the benefits of your Amex credit card during your US trip, keep these handy tips in mind: * Carry an Alternative: Consider carrying an alternative debit or credit card, or some cash, for smaller businesses that may not accept Amex. * Download the Amex App: Before you travel, download the Amex app. It provides useful features like the ability to freeze your card if it’s lost or stolen and offers easy access to customer services. * Update Contact Details: Ensure your contact details are up-to-date with Amex before you travel. This is crucial as their fraud prevention team may need to reach you if they have concerns about any transactions. * Always Pay in Local Currency: We can’t stress this enough – always opt to pay in USD to minimise fees.
Alternative for International Spending: The Wise Card
If you’re travelling to the US, packing a card like the Wise card can be a smart move to use alongside your Amex. It offers low-cost currency conversion and spending, often at more favourable mid-market exchange rates. This contactless international card allows you to spend in over 40 currencies worldwide, accepted wherever Visa or Mastercard are taken – including shops, restaurants, hotels, and on public transport. Key benefits include: * Low Fees: Generally lower fees compared to traditional credit cards for foreign transactions. * Mid-Market Exchange Rates: Access to the real exchange rate, without markups. * Fee-Free ATM Withdrawals: You can withdraw up to £200 per month from overseas ATMs fee-free (limited to two withdrawals). Be mindful of potential ATM operator fees. * Virtual Cards: Create virtual cards for added security, which can be managed through the Wise app. * Mobile Wallet Integration: Works seamlessly with mobile wallets like Apple Pay and Google Pay. You can manage all your Wise cards through the handy Wise app, allowing you to convert currencies, freeze cards if lost, and even send money to friends. Opening a Wise account and getting a Wise card typically involves a small one-time fee, with no monthly or subscription charges.
