What an International Driving Permit is
An International Driving Permit is a supplementary document that helps confirm your entitlement to drive abroad. It does not replace the national licence — it works alongside it.
It is most often requested in countries where the national licence cannot be read without translation, or where the supplier applies stricter requirements to foreign drivers.
When it is needed
If your licence is not in Latin script
If your licence carries no Latin transliteration, an International Driving Permit is very likely to be needed. It lets the supplier verify the details quickly and avoids disputes at handover.
If the country requires it
In some destinations local rental rules are stricter than they first appear. Even on a straightforward trip the desk may ask for the permit alongside the national licence.
If the supplier's terms say so
Sometimes the decision rests not with the country but with the individual company. One supplier accepts an ordinary licence while another asks for the permit even where it is not strictly mandatory.
When an ordinary licence is enough
In many cases the national licence on its own is sufficient. That is especially likely when it reads without translation, the details match the booking and the country requires nothing extra.
Even then it is worth checking the rules for the specific destination before booking — particularly when you book through an aggregator and collect the car at an airport or in a country with its own conditions.
What to check in advance
Whether the details match
The name on the licence, the booking and the card must agree. If they differ, the supplier may request further proof or refuse to release the car.
Whether a translation is needed
If your licence is not in Latin script, confirm in advance whether an International Driving Permit is enough or whether an official translation is required. Settle this before the trip, not at the desk.
What the country requires
Requirements differ not only by country but by rental type. Terms at an airport, in the city or with a local supplier can all differ.
How to avoid a mistake before booking
The safest approach is to check the document requirements together with the rules on deposit, card and driver age. That gives you the full picture and avoids an unexpected refusal at handover.
It also helps to read the neighbouring guides in advance so you can assemble the whole set of requirements before paying and choose a suitable car without extra risk.
