Does Car Rental in Portugal Accept American Express?

American Express runs on its own card network, separate from Visa and Mastercard, and European merchants — including some rental desks — don't always process it the same way, mainly because Amex charges merchants higher fees. That friction shows up directly in Portuguese rental terms: of the eight national companies compared on this site, only two name specific card networks at all, and they land on opposite answers.

Europcar's Portugal terms, verified July 2026, name Mastercard, Visa, American Express and Diners Club as accepted cards for its credit-card-only deposit. Centauro's terms, also verified July 2026, explicitly exclude American Express — along with Diners Club, Visa Electron and Maestro — from what it accepts for the nominative Visa/Mastercard debit or credit card its deposit requires. Goldcar, Record go, Sixt, Cael, Guerin and OK Mobility don't name specific card networks in the terms this guide tracks, so Amex acceptance there is simply unconfirmed either way.

Which companies actually work

Europcar — terms verified July 2026 name Mastercard, Visa, American Express and Diners Club for the credit-card deposit; it's still credit-card only, so a debit Amex (or any debit card) doesn't work there regardless of network.
Centauro — terms verified July 2026 explicitly reject American Express, Diners Club, Visa Electron and Maestro as substitutes for the nominative Visa/Mastercard card its deposit requires.
Goldcar, Record go, Sixt, Cael, Guerin, OK Mobility — none name specific card networks in the terms tracked on this site; don't assume Amex works, or doesn't, without asking directly.
Even where a company's terms name Amex, travellers have reported a rental desk's card terminal refusing an Amex card that American Express itself confirmed was active and working — a processing-level issue, not a card problem.
Amex acceptance for the deposit is separate from whether a company takes Amex for the online booking payment — the two steps can use different rules at the same company.

Step by step

Check whether your company's published terms name American Express at all before assuming a general "credit card required" line includes it — most of the eight companies compared here don't specify by network.
If you're considering Europcar, treat the written terms naming Amex as necessary but not sufficient, since a specific branch's card terminal can still decline it on the day.
If you're considering Centauro, don't rely on an Amex card in place of the required Visa or Mastercard debit card — its terms exclude it outright.
Email the company with your booking number and ask specifically "will you accept American Express for the deposit at pickup", not just "do you take credit cards" — get the answer in writing.
Bring a second card on a different network (Visa or Mastercard) as a fallback whenever you can, since a processing-level refusal at the counter isn't something a booking confirmation can fully rule out.

Frequently asked questions

Does Europcar accept American Express for the deposit in Portugal?

Yes, according to its Portugal terms verified July 2026 — Europcar names Mastercard, Visa, American Express and Diners Club as accepted cards for the credit-card deposit. It's still credit-card only; a debit card on any network doesn't work there.

Can I use an American Express card instead of a debit card at Centauro?

No. Centauro's terms verified July 2026 explicitly exclude American Express, Diners Club, Visa Electron and Maestro from the cards it accepts — its deposit specifically requires a nominative Visa or Mastercard card.

If a company's terms accept Amex, is that a guarantee it will work at the counter?

Not entirely. Traveller reports describe a rental desk's card terminal refusing an Amex card that American Express itself confirmed was active with no blocks, and the rental company unable to explain why. Terms describe what's contractually accepted; a specific branch's card-processing setup is a separate, less visible layer.

What about Goldcar, Record go, Sixt, Cael, Guerin and OK Mobility — do they take American Express?

Their published terms, as tracked on this site, don't name specific card networks — they say "credit card" or "debit card" generically. That means this guide can't confirm or rule out American Express for them; ask directly and get the answer in writing before relying on it.
