It’s the question that can stop your trip at the rental desk: is my driving licence enough, or do I need an International Driving Permit? 🪪 Get it wrong and you can be refused the car you booked, with no easy fix at the airport. The good news is the answer is simple once you know your category — for many visitors no IDP is needed at all, while for some it’s essential. This guide spells out exactly who needs one for Portugal and who doesn’t, so you arrive at the desk with the right documents and drive away without a hitch.
The one rule: Whether you need an IDP in Portugal depends on where your licence is from. EU/EEA licences need nothing extra. UK photocard licences are generally fine without one. US, Canadian, Australian and many other non-EU licences are often accepted in practice, but an IDP is cheap insurance and sometimes required — especially if your licence isn’t in the Latin alphabet. When in doubt, get the IDP before you travel; it’s easy and inexpensive at home, impossible to obtain once you’ve landed.
This is part of our Lisbon Airport car rental guides, alongside the documents and pickup process.
What an IDP actually is
An International Driving Permit is not a licence — it’s an official translation of your existing one, recognised internationally, that you carry alongside your home licence. It exists so that an official or rental agent who can’t read your native licence can still verify your details in a familiar format. You obtain it in your home country before you travel (typically through a motoring authority or automobile association); you cannot get one after you arrive in Portugal, which is the single most important thing to know.
Because it’s only a translation, an IDP is worthless on its own — it must always be presented together with your valid home licence.
EU and EEA licences: nothing extra
If your driving licence was issued by an EU or EEA country, you’re set — your licence is valid throughout Portugal and you need no IDP or any other document. Just carry your licence as normal. This covers the large share of visitors driving on European licences, for whom the whole IDP question simply doesn’t apply.
🇬🇧 UK licences: generally fine
Holders of a UK photocard driving licence are generally able to rent and drive in Portugal without an IDP. Carry your photocard licence as usual. As with all visitors, the rental company will also want your passport and a payment card — the full list is in what documents are needed for Lisbon Airport car rental. If your UK licence is an older paper version without a photo, an IDP is sensible to avoid any doubt.
US, Canadian, Australian and other non-EU licences
This is where it pays to be careful. Licences from countries like the US, Canada and Australia are often accepted in practice by rental companies in Portugal, and many visitors drive on their home licence without issue. But “often” isn’t “always” — individual rental companies set their own policies, and an officer or agent has the right to ask for an IDP. The risk is small but the consequence (being refused the car) is large.
The sensible move: if your licence is from outside the EU/EEA, get an IDP before you travel. It’s inexpensive, quick to arrange at home, and removes all doubt. Think of it as cheap insurance against a ruined first day.
Licences not in the Latin alphabet
There’s one group for whom an IDP is effectively essential: drivers whose licence is not written in the Latin alphabet (for example, licences in Arabic, Cyrillic, Chinese or Japanese script). Here the IDP’s role as a translation matters most — without it, a rental agent genuinely cannot read or verify your licence. If this is you, treat the IDP as a must-have, not an optional extra.
Quick reference: who needs an IDP?
| Your licence is from… | IDP needed? |
|---|---|
| An EU / EEA country | No |
| The UK (photocard) | Generally no |
| US / Canada / Australia | Recommended (sometimes required) |
| Other non-EU country | Recommended |
| Anywhere, non-Latin alphabet | Yes — effectively essential |
When the table says “recommended”, read it as: not always demanded, but cheap protection against being refused. The cost of an IDP is trivial next to the cost of losing your rental.

What the rental desk will check
At pickup, the agent verifies you’re legally able to drive their car. They’ll look at your licence (and IDP if applicable), check it covers the vehicle category and hasn’t expired, and confirm you meet the company’s experience and age requirements. Younger drivers should also read minimum age to rent a car in Lisbon, since age rules stack on top of licence rules. Have everything ready together — licence, IDP if you have one, passport and card — so the check is quick. The general process is in how to rent a car at Lisbon Airport.
How to get an IDP before you travel
Arranging an IDP is straightforward, which is exactly why it’s not worth skipping. In most countries you apply through the official motoring authority or a recognised automobile association — often by post or in person, sometimes online — with your valid licence, a passport photo and a small fee. It’s usually issued quickly, and it’s valid for a set period (commonly a year), so you can sort it well ahead of your trip without it expiring. The one constraint that catches people is timing: because you can only get it in your home country, leaving it until you’ve landed in Portugal isn’t an option. Apply a couple of weeks before you fly to be safe, keep it with your travel documents, and you’ve removed the single most avoidable reason a rental desk turns someone away. For the modest cost and effort involved, it’s some of the cheapest peace of mind a traveller can buy.
Common IDP myths to ignore
A few misconceptions lead people astray, so it’s worth clearing them up:
| Myth | Reality |
|---|---|
| “An IDP lets me drive without my licence” | False — it’s only valid alongside your home licence |
| “I can buy one when I arrive” | False — it must be obtained in your home country |
| “Every foreign driver needs one” | False — EU/EEA and UK photocard holders generally don’t |
| “It’s expensive and complicated” | False — it’s cheap and quick to arrange at home |
| “It never expires” | False — it’s valid for a limited period only |
The thread running through all of these is the same: an IDP is a simple, cheap translation document with one hard rule — get it at home, carry it with your licence. Treat it that way and it does its job invisibly. Believe the myths and you risk either wasting effort or, worse, arriving unprepared. When your category in the table above says “recommended” or “essential”, a short trip to your local motoring authority before you fly settles the matter for good.
Your licence checklist
Before you fly:
- EU/EEA licence? Bring it as is — nothing more needed.
- UK photocard? Bring it; you’re generally fine without an IDP.
- Non-EU licence? Get an IDP at home — cheap insurance.
- Non-Latin-alphabet licence? An IDP is essential — don’t skip it.
- Always carry both the IDP and your home licence together.
- Get the IDP before you travel — you can’t obtain one in Portugal.
That’s the whole decision. A few minutes of preparation at home means no nasty surprise at the desk.
FAQ
Do I need an International Driving Permit to drive in Portugal? It depends on your licence. EU/EEA and UK photocard holders generally don’t. US, Canadian, Australian and other non-EU drivers are often fine but should get one as cheap insurance — and it’s essential for non-Latin-alphabet licences.
Can I get an IDP after I arrive in Portugal? No — you must obtain it in your home country before you travel, usually through a motoring authority or automobile association. This is the key reason to sort it early.
Is an IDP a replacement for my licence? No. It’s only an official translation and is invalid alone. You must always carry it together with your valid home driving licence.
Will a US licence be accepted in Portugal? Often, yes — many US visitors drive on their home licence. But policies vary by rental company and an IDP can be requested, so getting one before you travel removes the risk.
Do EU citizens need anything extra to rent in Portugal? No. An EU or EEA licence is valid across Portugal with no IDP or extra paperwork. Just carry your licence, passport and a payment card.
What happens if I turn up without a required IDP? You could be refused the car, with no way to get an IDP locally. That’s why non-EU drivers should arrange one at home — the small effort prevents a ruined first day.
