Terms and Conditions

• Retain your reservation confirmation number as it is necessary for modification, cancellation or no-show refund requests. Changes to your prepay reservation must be made either on Avis.com, Avis.com.au or Avis.co.nz or at the rental counter. At time of change, current rates, taxes and fees apply.
• Your credit or debit card will be charged upon reservation confirmation. Method of prepayment toward your rental may not be changed after confirmation.
• Debit cards are not accepted at some Avis locations and are not a recommended form of prepayment.
• While a debit or prepaid charge card is an acceptable form of rental prepayment online, they may not be accepted for the credit hold required when you pick up your vehicle.
• Please review the terms and conditions on our confirmation page regarding credit or debit card acceptance at the location. To release the vehicle to you at time of pick-up, all rental terms and conditions must be met, regardless of your original prepayment.
• Prepaid debit and gift cards are not acceptable methods of credit identification to pick up a vehicle at any location. One of the above mentioned cards must be presented. Prepaid debit and gift cards are accepted at time of return only.
• In the U.S., debit or check cards may be used at the end of the rental for payment of rental charges.
• The same credit or debit card used to complete an online Pay Now reservation must be presented at the rental pick-up counter as a form of identification. At airport locations, proof of a return airline ticket is also required when using a debit card.
• Generally, at the time of rental, we'll require a credit card hold of total estimated charges.  However, many rentals may require an authorization hold of the estimated rental charges plus $200 USD.  If you have prepaid with a debit card, the hold will be $250 USD. A prepaid charge card is not accepted for this required hold and in case of reservation with non US currency, a credit card with same currency of reservation with equivalent USD amount would be required.
• The card presented at pickup will be the card of record for the rental.
• If you use a debit card at a location that accepts them, we will perform a credit check to ensure worthiness before releasing the vehicle and you must also present a second form of current identification.
• Prepaid reservations are only offered at participating locations.
• Upon paying your rental with a debit card, Avis will generally request an authorization hold against your account for the estimated charges of the rental but reserves the right in its sole, discretion, to request extra value based on certain factors as we deem appropriate. Many rentals may require an authorization hold of the estimated rental charges plus $200 USD.  Rentals of 4 days or more may require an authorization hold of the estimated rental charges plus $300 USD. If you have prepaid with a debit card, the hold will be $250 USD. Some exceptions may apply. THESE FUNDS WILL NOT BE AVAILABLE FOR YOUR USE.
• If you selected Fuel Service Option, fuel price isn't included in your reservation total, but prevailing market rate will be added when you return your vehicle.
• Avis accepts most major credit cards as credit identification at the time of rental. Accepted credit cards: Avis Charge Card, American Express, AT&T Capital, Diner's Club Intl, Discover, China Union Pay, JCB, MasterCard, and Visa. Some locations may not accept each of the referenced cards.
• Coupons may be applied to prepay rentals. Vouchers or Avis rental certificates cannot be used in conjunction with a prepay reservation.
• Gift Cards (Avis or any other) are not allowed on prepay reservations.
• Most U.S. locations also accept bank debit cards with the Visa or MasterCard logo as credit identification at the time of rental if you are at least 25 years of age. In most cases, U.S. locations will perform a credit check for debit card renters to determine credit worthiness at the time of rental. The renter must meet Avis' minimum criteria in order to rent.
• When the rental is over, we will process the reversal but the bank may take time to post it back to the account - unless you already paid toward your rental, in which case the hold will be $250 USD. While this hold is in place, the funds will not be available for your use.
• Avis is not responsible for any returned checks or overdraft fees based on this policy.
• Your quoted rental rate is based on the exact parameters (locations, dates, etc.) of your particular rental - changing your confirmed reservation parameters could result in a different rate.
• There is no fee to modify a reservation related to: vehicle type, options (GPS, protections, etc.), rental period dates/times, adding other drivers or switching between participating prepay pick-up locations within the same country. However, making such changes may result in changes to the overall rental terms and the original price quoted is subject to change to reflect those changes. To change to a non-participating location or one outside of the original pick-up country, you must cancel your original reservation (with applicable cancellation fee) and re-book at then current rates.
• Non-permissible changes include: method of prepayment; name on reservation; changing your pick-up to a non-participating prepay location or one outside of the original pick-up country. If you still wish to make these changes, you must cancel your original prepay reservation with applicable cancellation fee and re-book at then current rates.
• At time of rental pick-up, location rental qualification rules apply. The name on all rental credentials (license and credit or debit card) must match the name on the reservation. If the names do not match, it is deemed a non-permissible change to your prepay reservation and must follow procedures to cancel and re-book at then current rates (with applicable cancellation or no-show fees).
• At the time of pick up, driver must present a valid driver's license and credit card (or debit card at participating locations) in the driver's name. A prepaid charge card is not an acceptable credential. All drivers must have a safe driving record.
• At time of pick up, driver must present a valid, drivers license and credit or debit card in the driver's name. If the drivers license is not U.S.-issued, you must present your drivers license and either a passport or a Canadian enhanced license in the driver's name.
