Sometimes, yes—but not always. Visitors from the United States or Canada may encounter a larger credit-card security hold when renting a car in Italy, including Sardinia. Yet there is no single Italian or North American deposit amount. The rental company, pickup branch, car category, insurance package and payment card all influence the amount reserved on your card.
What is a rental car security deposit?
A security deposit is usually a preauthorization hold, not a final charge. It temporarily reduces the credit available on your card to cover potential extra costs, such as fuel, damage, late return or contract charges. A hold is different from the rental price and from the insurance excess (also called a deductible), even though a company's deposit policy may depend on the excess.
Real examples: Italy versus the United States
According to Europcar's official deposit policy, a prepaid rental in Italy generally requires a €500 deposit; for a non-prepaid rental, the hold includes the rental cost plus the deposit. Its Italian deposit can fall to €300 with protection reducing the damage excess or €100 with qualifying zero-excess protection. The Keddy brand has a stated €800 deposit.
By comparison, Avis's US rental terms state that many prepaid rentals require a $250 authorization hold; non-prepaid rentals commonly require the estimated rental charges plus $200, with variations by location and circumstances. Enterprise USA explicitly says deposit amounts vary by branch. These are examples from different companies, not evidence that all Italian rental deposits are higher than all American deposits.
What about Canada?
Canada has its own rental policies and should not be treated as identical to the United States. For example, Avis's customer guidance describes a Canadian authorization that may be based on the estimated charges or CAD $750, whichever is greater, depending on the applicable rental policy. Always consult the Canadian branch's terms rather than applying a US figure to a Canadian booking.
Why might the hold be higher in Sardinia?
There is no verified universal Sardinia surcharge. Instead, the amount may reflect the specific rental company's standard Italian policy, vehicle class, insurance excess, card requirements and branch terms. A small economy car booked with qualifying protection may have a lower hold than a premium SUV without it. Rental comparison sites may show an attractive daily rate while displaying the deposit requirement only in the detailed rental conditions.
Does full insurance eliminate the deposit?
Not necessarily. Insurance purchased directly from the rental company may reduce the deposit if the company's terms say so. Third-party reimbursement insurance purchased from a broker or comparison website often does not change the rental desk's hold, because the rental company still applies its own damage excess and security policy. Ask the desk or provider for the exact hold amount after your chosen coverage—not merely whether the booking says “full protection.”
Credit card versus debit card: what should you bring?
For travel in Sardinia, the safest preparation is a physical credit card in the main driver's name with sufficient available credit. Some rental companies accept debit cards under specific conditions, but acceptance varies by branch and vehicle class. A card that worked for a rental in the USA is not automatically accepted at an Italian airport. Confirm whether your exact card type is eligible, whether a physical card is required and whether a second card is needed for premium vehicles.
How much available credit do you need?
Consider a simple example: a prepaid rental costing €240 with a €500 deposit may require €500 in available credit at pickup for the security hold, in addition to the amount already paid. For a non-prepaid booking under a policy that authorizes the rental price plus deposit, the total hold could instead be €740. This is an illustration of how the policy works, not a quote for a particular Sardinian airport. Leave extra room for other travel expenses and exchange-rate fluctuations.
When will the deposit be released?
Once the car is returned and the rental account is settled, the company normally releases the unused authorization. However, your bank may take additional time to make the credit available again. Europcar's published policy lists a typical release process of four business days from invoicing for various completed rentals, with exceptions. Do not assume the money becomes available the moment you hand back the keys, particularly if you have another rental or hotel deposit shortly afterward.
What to check before renting at Alghero, Olbia or Cagliari Airport
Before booking, open the rental terms for your exact pickup location and check: the deposit amount in euros; the damage excess; the card type accepted; whether protection changes the hold; the amount due at pickup; and the release policy. Save the terms and booking confirmation offline. At pickup, photograph the vehicle's condition, confirm the fuel policy and request a clear receipt at return. If you cannot meet the deposit requirement, contact the supplier before arrival rather than relying on an agent to make an exception.
Frequently asked questions
Is a €1,000 deposit normal in Italy?
It can occur with certain suppliers, vehicles or insurance arrangements, but it is not a standard amount for all Italian rentals. Check the exact terms.
Will my US credit card work in Sardinia?
Major international credit cards are commonly accepted, but individual rental companies may impose restrictions on card type, cardholder name, available credit or physical presentation. Verify your supplier's rules.
Is the deposit actually charged?
Usually it is a temporary preauthorization, not a completed purchase. It nevertheless reduces available credit until released.
Can I avoid the deposit by buying insurance?
Sometimes qualifying supplier protection reduces it, but it does not always remove it. Third-party excess-reimbursement insurance may leave the desk deposit unchanged.
Are deposits always lower in North America?
No. Some US and Canadian branches require substantial holds, particularly for certain vehicle classes, payment methods or renters. There is no reliable countrywide rule.
The bottom line
Italian rental car holds can be higher than familiar US examples, but country alone does not determine the deposit. Europcar Italy's €500 prepaid hold and Avis USA's $250 prepaid hold illustrate a real difference between two published policies, not a universal Italy-versus-America average. For a stress-free Sardinia road trip, verify the actual deposit and card requirements before you reserve—not at the rental counter after your flight.
