Yes, a Belgian credit card pays in the United States, on one condition: have it opened up before you leave, because the country falls outside Belfius's Europe zone and banks generally block cards outside Europe. The trouble comes next, at the pump, the hotel and the rental desk, where the bank holds more than the displayed price.
Do you need to unblock your Belgian card before leaving for the US?
Yes, and this step comes before everything else. Wikifin (French), the financial education site of the FSMA, advises checking that your cards are activated before departure, because banks generally block cards outside Europe (page updated on 17 February 2025). Belfius's "Pays Zone Europe" list, read on 2 September 2026, puts Russia and the Cayman Islands in Europe, but neither the United States nor Canada.
The route through each bank's app is described in our page on the Belgian credit card abroad, and the general frame in the pillar on travelling with a Belgian credit card. Here, the card is already open.
To check the evening before you leave:
- the region or temporary exemption, active for the whole stay;
- the available limit, since a rental deposit will add to your spending;
- a second card, stored elsewhere;
- a few dollars in cash, as Wikifin advises;
- the number +32 78 170 170 saved in your phone.
To my mind, the credit card is the only one to pull out over there. The debit card works too, but some hotels will not take it as a guarantee.
US pumps ask for a ZIP code your card does not have
The first refusal often comes at the pump. Some terminals ask for a five-digit ZIP code, and a Belgian postcode has only four. I found no Belgian issuer page covering this case, and Wikifin's US page says nothing about it.
Milesopedia (French), page updated on 7 October 2026, is aimed at Canadian cards: the first three characters of the code then "00", otherwise pay inside. The American rental firm Hola Car Rentals suggests padding the code with zeros up to five digits, with no guarantee and without saying on which side. Better to propose nothing than to guess.
The reliable way out: pay inside, giving the cashier your pump number and an amount. The same firm notes that mobile payment sometimes avoids the code entry; our guide to Apple Pay in Belgium explains how to add a Belgian card.
Even when accepted, the card triggers a hold before the first litre: usually 1 dollar, sometimes up to 100, and some pumps place two, for example 75 dollars then the amount of the fill-up (Wikipedia, article "Authorization hold", read on 25 October 2026). On a debit card, they can overdraw the account. On a credit card, they only nibble at the limit.
How much does the bank hold at the hotel, the rental desk and the restaurant?
According to the same article, the hotel or the rental firm holds the estimated total plus a margin, for example 15% or 250 dollars for a rental. On a credit card, the hold can last up to 30 days depending on the issuer, against one to eight working days on a debit card. No official Belgian source publishes a release time (see our credit card timeframes). At a restaurant, the terminal often holds 20% more than the bill to cover the tip, which is added afterwards on the receipt.
| Situation | Hold on the card | What to do |
|---|---|---|
| Automated pump | 1 to 100 dollars, sometimes two holds | Pay inside if the ZIP code is refused |
| Hotel | Estimated total plus a margin | Keep a limit well above the bill |
| Car rental | Estimate plus, for example, 15% or 250 dollars | Credit card in the driver's name |
| Restaurant | Bill plus a margin, for example 20% | Keep a few dollars for the tip |
| Debit card at the hotel or rental desk | Refused by some | Bring a credit card |
Rental firms' requirements are detailed in our guide to car rental with a credit card, and limit adjustments in the one on the credit card limit.
How much does a dollar payment cost with a Belgian card?
Between 1.5 and 2% exchange commission with a credit card, according to Wikifin (French, updated 17 February 2025). With a debit card, 1.6% in transaction fees come on top. On 2,000 euros spent, the credit card costs 30 to 40 euros in exchange fees, the debit card 62 to 72 euros. The issuer-by-issuer detail is in our guide to paying abroad.
If the terminal offers to charge you in euros rather than dollars, decline: Wikifin writes that the local currency is generally cheaper, because the conversion on the spot is done by the merchant.
Some ATMs add their own fee; Wikifin suggests asking for cash at a shop till with a card purchase, sometimes cheaper. KBC offers a free foreign-currency account with a current account, up to 1,500 euros of exchange per month, with no exchange commission on debit card payments and withdrawals (read on 2 September 2026).
A gap remains: KBC states no commission for the dollar and publishes a percentage only for European Economic Area currencies.
What to do when the card is refused at the till?
- Retry with the chip, then with another card or mobile payment.
- Open the bank's app: does the region cover the United States, is the limit enough?
- At the pump, pay inside.
- Otherwise, call the number on the back of the card, never one received by message.
Card Stop (French) is for loss, theft or fraud only, and only the issuing bank can unblock a card that has been found. Procedure: our guide to a lost or stolen card.
One question stays unanswered on my side: PIN or signature in the United States? Wikifin does not mention it and I found no Belgian issuer page that does. Put it to your bank before you go.
On 25 October 2026, Wikifin's US page dates from 17 February 2025 and mentions neither the pump, nor the ZIP code, nor the tip.

Sophie L. worked eight years in a Belgian bank branch, first as a credit adviser and then in customer relations, before going independent in 2021 and settling in Louvain-la-Neuve. Her work starts with the issuers' official fee schedules, from the high-street banks (ING, BNP Paribas Fortis, KBC, Belfius) to the neobanks (Revolut, N26, Wise), reduced to five comparable lines: annual fee, currency conversion charge, borrowing rate, spending limits and bundled insurance. Every price on this site carries the date it was checked: the annual-fee grid was gone through line by line on 12 August 2026, after Belfius moved its Beats Star package to 5.90 € a month in February. If an issuer does not publish a figure, she writes that down instead of estimating it. For readers who moved to Belgium, she spells out what a Belgian issuer expects from an applicant with no local credit history.
