In 2026, Uber Cash is generally restricted to the country or currency in which it was originally purchased or earned. If you have a balance of Uber Cash in U.S. Dollars (USD), you will not be able to use it for rides in the United Kingdom (GBP), the European Union (EUR), or Mexico (MXN). This is due to the complexities of currency conversion and local financial regulations governing stored-value accounts. When you travel internationally, your Uber app will automatically default to the local currency and require a valid credit card, debit card, or digital wallet (like Apple Pay) that supports foreign transactions. Uber has introduced a "Preferred Currency" feature that allows you to see prices and pay in your home currency while abroad for a small fee (typically 1.5%), but even this feature cannot be used in conjunction with Uber Cash. If you have a significant balance, it is best to use it for rides or Uber Eats orders within your home region. Some regional "Vouchers" may also be restricted to specific cities or events, so always check the terms in your "Wallet" before traveling abroad.
