The International Driving Permit: What It Is, What It Isn’t
A twenty-dollar translation booklet that is legally required in about a dozen European countries, useless on its own, and dead after twelve months. Written for US travellers; verify anything with a fee or a border attached before you rely on it.
Almost everything written about the International Driving Permit is written by somebody selling one, which is why the internet is full of confident pages telling you it is a licence, that you need it everywhere, and that a website in a hurry can issue you one for $79. All three are wrong. Here is the plain version.
What it actually is
The IDP is a grey paper booklet that translates your existing driving licence into ten languages, under the 1949 UN Convention on Road Traffic. That is the entire function. It confers no driving privileges of its own, it is not a licence, and on its own it is worth nothing at all — it is only valid presented together with the physical licence it translates. Leave the licence in the apartment safe and the IDP in your wallet, and you are driving on neither.
This matters more than it sounds, because the confusion runs in one specific direction. People assume the IDP grants them something. It does not. It removes an excuse — the excuse that a police officer in Thessaloniki cannot read Illinois.
What it costs, and who may sell it
Exactly two organisations are authorised by the US State Department to issue them: the American Automobile Association (AAA) and the American Automobile Touring Alliance (AATA). Everyone else is selling you a souvenir. The FTC has published a consumer alert about this; the US Embassy in Japan notes that a legitimate permit costs about $20 while fraudulent sites charge up to $300.
- The fee is $20 at AAA, plus tax where applicable. No membership required — a point AAA states outright and the resellers rely on you not knowing. AATA charges $20 plus a $9 photo-processing fee, with shipping from $16 to $165 depending on how much of a hurry you are in.
- You need: to be 18 or over, a valid US licence, and two identical 2″×2″ passport-style photos signed on the back. Mail applications also want a photocopy of both sides of the licence.
- It is valid for one year and cannot be renewed — when it expires you apply again from scratch. You can post-date the start by up to six months from the application date, which is a small and genuinely useful feature almost nobody uses.
- It dies with your licence. If the state licence expires, the translation of it expires too.
The case for
It is cheap in the way that insurance is cheap. Twenty dollars against the possibility of a roadside conversation you cannot win is not a close call. Rick Steves puts the asymmetry better than anyone: “If all goes well, you’ll likely never be asked to show it — but the permit is a must if you end up dealing with the police.”
In about a dozen European countries it is the law, not a suggestion — Italy, Greece, Spain and Austria being the ones a slow traveller is most likely to drive in.
It is a second photo ID that is not your passport. On a long stay this is worth something on its own. Handing a booklet to a rental clerk, a police officer or a hotel desk instead of the document you cannot afford to lose is a habit worth having.
It removes an argument at the worst possible moment. Not the rental desk — after a collision, when a claims adjuster is reading the rental contract closely for the first time and the contract says you warranted you were legally entitled to drive.
The case against
It is a translation, not permission. Where your home licence is not accepted at all, the IDP does not fix that. China is the clean example: it does not recognise the IDP in any form, and visitors drive on a temporary Chinese permit or not at all.
Nobody will ask you for it, right up until somebody does. Rental desks in Italy hand over keys to unaccompanied US licences daily, which trains a whole generation of travellers to conclude the requirement is theatre. It isn’t; it is simply enforced by police rather than by Hertz.
It expires quietly. Twelve months, no renewal, no reminder, and it is a piece of paper in a bag rather than an app that notifies you.
It does not solve residency. Stay somewhere long enough — typically six to twelve months — and most countries stop treating you as a visitor and expect you to convert to a local licence. Japan is explicit: twelve months on the permit, then a Japanese licence. The IDP is a document for passing through, not for living.
The market around it is genuinely predatory. The scam sites outrank the real ones, look better, and process faster, because they are not doing anything.
The twelve-month problem
This is the part written nowhere, because it only exists for people who leave for longer than a holiday.
A twelve-month permit is fine for two weeks in Tuscany and awkward for fourteen months in the Balkans. It expires while you are out there, and reapplying requires two fresh passport photos, a scan or photocopy of your licence, and something to post them to. AATA takes applications from overseas online; AAA will accept a mail application from abroad through its Florida office. Both work. Both take longer than you think from a village with one post office.
Then the sharper edge, and it is the one worth putting on a checklist: the IDP is only as alive as the licence underneath it. Several states shorten the renewal cycle past a certain age, and some require an in-person visit or vision test rather than an online renewal — which is a very different problem when you are seven time zones away with eight months left on the lease. Check your own state’s rule for your own age bracket before you go, not after. If the licence renewal falls mid-trip and cannot be done remotely, that single line item can decide when you fly home.
The workable pattern for a long departure: renew the licence early if you are anywhere near the window, get the IDP with a post-dated start so the twelve months begin when you actually land, and put both expiry dates in the same calendar as the visa clock and the insurance renewal. They are one document set, not four.
Where it actually bites
Three different situations get collapsed into one question, and they have different answers.
At the rental counter. Inconsistent. Some agencies ask, most do not, and the ones that do tend to be at airports in countries where the requirement is real. The failure mode here is annoying rather than expensive: no car.
At a police stop. This is the one the permit exists for. In a country that requires it, being without one is a paperwork offence in its own right, on top of whatever stopped you.
After a crash. The expensive one, and the least discussed. Rental agreements and the collision products sold beside them are written on the assumption that you were driving lawfully. Whether a missing IDP actually voids cover depends on the contract and the country, and anyone who tells you flatly that it does is guessing — but it hands the other side an argument, and you will be having it in a second language.
By country
| Where | The situation |
|---|---|
| Required — get one Italy, Greece, Spain, Austria, Poland, Czechia, Hungary, Slovenia, Slovakia, Estonia, Bulgaria, Romania | Rick Steves’ working list for Europe, and the one most travel-forum arguments end at. Italy and Greece are where enforcement stories actually come from |
| Required, and only obtainable before you fly Japan | The 1949-convention permit, valid twelve months, and it cannot be issued in Japan. Arrive without one and you do not drive |
| Will not help China | The IDP is not recognised. Visitors use a temporary Chinese permit arranged locally |
| A different booklet Brazil, Uruguay | AAA’s application still carries a separate Inter-American box for these two. Whether it is still needed is genuinely disputed — both are now Vienna Convention parties. Ask the rental company in writing |
| Not required UK, Ireland, France, Germany, the Netherlands, most of Latin America, Canada | A US licence is accepted. The permit is harmless and occasionally convenient, but you are buying a second photo ID, not a legal requirement |
The verdict
If you are driving anywhere in Europe, get one. The fee is $20, the process is a form and two photographs, and the entire case against it is the mild indignity of buying something you will probably never take out of the glovebox. That is not a real argument against a twenty-dollar document.
If you are not driving at all — and on a slow trip built around one flat for a month at a time, a great many people are not — skip it. It is not a general-purpose travel document and it will not make anything else easier.
The only genuinely difficult version of this question belongs to the long-stay traveller, and it is not whether but when. Buy it too early and it expires in the middle of the trip; buy it too late and you are chasing passport photos in a town that does not have a photo booth. Post-date the start, put the expiry beside the visa dates, and check your licence renewal before anything else.
Nothing on this page has anything to sell you, which is exactly why it is short: the correct answer is a twenty-dollar form from one of two organisations, and everyone charging more than that for it is charging you for the search result.
Fees, requirements and country lists all move. Everything here was checked against AAA, AATA, USA.gov, the FTC and the US Embassy in Japan in August 2026 — reverify in the week you apply, and buy only from AAA or AATA.
