Does National require an IDP in Portugal?

National in Portugal: the policy in plain terms
Asks for a licence translation for non-Latin-alphabet licences and where local rules call for one. Business-traveller brand known for Emerald Aisle.
Non-EU visitors should carry an IDP to drive and rent in Portugal.
In Portugal specifically, many rental companies and local authorities in Portugal ask foreign drivers to present a translation of their licence alongside the original, so National will typically ask for it at the counter. Requested for licences issued outside the EU/EEA.
National runs a global network; at its Portugal desks, foreign renters are asked for an International Driving Permit in the 1949 Geneva and 1968 Vienna Convention format alongside the original licence. Portugal drives on the right, uses the EUR, and sets a minimum driving age of 18, so an IDP is the document that removes any doubt at the counter.
What to bring to the National counter in Portugal
- Your original national driving licence (the IDP never replaces it).
- Your International Driving Permit in the 1949 Geneva and 1968 Vienna Convention format.
- Your passport and a payment card in the main driver's name.
- Local payment for the EUR deposit; Portugal drives on the right with a young-driver surcharge under 25.
Driving rules in Portugal National renters should know
- Electronic tolls (Via Verde) — arrange with your rental car.
- Reflective vest and triangle required.
- 0.05% alcohol limit; 0.02% for new drivers.
- Dipped headlights in tunnels.
National's rental terms that affect your IDP booking
The minimum age to rent is typically 21 (18 in Michigan and New York, as required by state law); renters aged 21-24 pay a "Youthful Surcharge" of approximately $25 per day (varies by location, lower in some states such as $5/day in New York) and may be restricted to certain car classes.
A major credit card (Visa, MasterCard, Amex) in the primary renter's name with sufficient available credit is required; National generally does not accept debit cards, and renters without a ticketed return travel itinerary must provide a hold/deposit typically between $300 and $400 depending on location and vehicle class.
The renter's spouse or domestic partner who meets the same age and licence requirements drives free; other additional authorized drivers cost about $15 per day (typically $5/day in New York), and must be at least 21 with a valid licence. National requires a valid, unexpired full driver's licence held by the renter; for under-25 drivers some locations require the licence to have been held for at least one year, though National does not publish a uniform minimum tenure across all locations.
Vehicles rented in the U.S. or Canada are prohibited from being driven into Mexico; U.S.-Canada cross-border travel is generally permitted but one-way US/Canada drop-offs are limited to participating locations, and rentals originating in certain Mexican cities (e.g. Tijuana, Mexicali, Hermosillo, Monterrey, Saltillo) may cross into the U.S. after purchasing an extension of liability protection (about $10 USD/day).
National states that an International Driving Permit (IDP) is commonly requested in select countries and is generally recommended when travelling abroad; specifically, overseas travelers whose licence uses a non-Roman alphabet may need to present an IDP alongside their home-country licence.
Once you collect the keys in Portugal
Portugal mixes staffed toll plazas with fully electronic 'ex-SCUT' motorways that have no booths and read your plate via Via Verde. Rental cars carry a Via Verde transponder (about EUR 1-2/day plus tolls billed to your card); independent drivers can use EASYToll, registering a card to the plate at a border/airport kiosk for EUR 1 setup plus per-transit charges.
In Lisbon paid zones are run by EMEL (pay by machine or app), and Porto and other cities have similar metered zones; bays are scarce and illegal-parking fines reach about EUR 300. Peripheral park-and-ride plus public transport into the centre is the practical option.
Speeding fines start around EUR 60 and rise sharply, and police can demand on-the-spot payment from non-residents (a deposit) for offences such as speeding, phone use or no seatbelt before allowing you to continue. Camera fines to foreign drivers are passed on by rental firms with an admin fee.
Call 112 for emergencies (the GNR or PSP handle road policing). For a minor crash, complete the European Accident Statement (Declaracao Amigavel) jointly with the other driver; call police if there is injury, a dispute, or a driver without documents, and do not move vehicles before documenting an injury crash.
