Does Enterprise require an IDP in San Marino?
Written by Daniel MercerUpdated July 2026
Enterprise in San Marino: the policy in plain terms
Asks for a licence translation alongside your home licence in many countries across Europe, Asia and South America. The world's largest car-rental brand by fleet size.
This enclave inside Italy drives on the right and follows Italian-style rules; an IDP is rarely required but useful for non-EU visitors.
In San Marino specifically, san Marino lets visitors drive on a valid foreign licence, but Enterprise still asks for a licence translation if your licence is not printed in the Roman alphabet — and it removes any doubt at the counter. Cars are typically rented in Italy; an IDP helps non-EU drivers.
Enterprise runs a global network; at its San Marino desks, foreign renters are asked for an International Driving Permit in the 1949 Geneva and 1968 Vienna Convention format alongside the original licence. San Marino drives on the right, uses the EUR, and sets a minimum driving age of 18; an IDP is still the safest way to avoid a refused booking.
What to bring to the Enterprise counter in San Marino

- Your International Driving Permit in the 1949 Geneva and 1968 Vienna Convention format.

Enterprise's rental terms that affect your IDP booking
Enterprise's minimum rental age is 21 in most of the U.S. (18 in Michigan and New York, and 18 for U.S. government employees on official orders); renters aged 21-24 pay a "Young Renter Fee" that typically averages around $25/day but varies by location (e.g., 21-24 is $15.75/day in Michigan and $30.75/day in New York, with 18-20 fees of $36.50 and $64.75/day respectively).
The contract holder must present their own credit card in their name with sufficient available credit; deposits typically run between $200 and $850 depending on location and vehicle class (airport holds are typically about 120% of the rental). Debit cards bearing a Visa, Mastercard, or Discover logo may be accepted at some locations, but at airports only with a ticketed return-travel itinerary, and prepaid cards are not accepted.
Each additional authorized driver is typically charged about $15.00 per day, but a renter's spouse or domestic partner who meets the same age and licence requirements is added at no charge. Enterprise requires each renter and additional driver to hold a valid, unexpired driver's licence; it does not publish a fixed minimum holding period in the U.S., though young-renter (under-25) restrictions and surcharges apply instead.
Taking a U.S.-rented vehicle across the Mexican or Canadian border requires advance approval; renters must contact the renting branch or call center for the correct procedure and any required insurance, and cross-border travel is restricted or prohibited at many locations. One-way rentals are offered but availability and drop-off fees vary by branch.
For renters under 25, Enterprise states it does not accept an International Driver's Permit as identification; a valid photo driver's licence is required. Foreign renters generally need their home-country licence (an IDP is recommended as a translation supplement but is not a stand-alone substitute for the licence).
Once you collect the keys in San Marino
San Marino has no motorways and no toll roads, so no vignette or toll payment is required; the connecting Italian roads (SS72) are likewise toll-free.
Parking in the historic Città (old town) is restricted to colour-coded paid bays and several public garages, since the walled centre is largely pedestrian-only; pay at meters and avoid double-white-line and crossing areas.
Italian-style on-the-spot fines apply for speeding, no seatbelt and handheld phone use (drink-drive limit 0.05%); rental companies operating across the Italy border pass camera fines back to the hirer with an admin charge.
Call 112/113 for police; exchange details and complete the European Accident Statement (CID/constat) form, and do not move vehicles after an injury crash until authorities attend.
