Some corporate cards allow international ATM withdrawals, but availability depends on the card issuer’s policies and the company’s program settings. ATM withdrawals are not permitted on Ramp cards, including those used internationally.⁠⁠⁠⁠ For cash-only situations, use out‑of‑pocket reimbursement instead.⁠⁠​

Most corporate cards can be used internationally, but whether foreign transactions work automatically depends on the issuer—some require you to explicitly enable international use or notify travel plans, while others allow it by default but may block transactions for fraud prevention. Ramp cards work internationally by default and do not require enabling foreign transactions in advance.

For purchases made abroad, the card network (Visa or Mastercard) converts the foreign currency to USD using its daily exchange rate, typically based on the settlement date. A network assessment fee of about 1% may apply and issuers may add foreign transaction fees, bringing total costs to roughly 0–3.5% depending on the card.

When a merchant requires address verification for a transaction in another country, the verification may fail or be unavailable because Address Verification Service (AVS) support outside the U.S. is limited and inconsistent.

International charges post days later at a different amount because of the delay between authorization and settlement, combined with currency exchange rate fluctuations during processing.
