However, some rental companies may accept other forms of payment or offer alternative options for customers without a credit card. It is recommended to contact the rental company directly to inquire about their payment options.

The cancellation policy for car rentals in Paraná may vary between rental companies. It is important to review the terms and conditions of your reservation before making the booking.

It is recommended to check the specific rental company's cancellation policy before making a reservation.

It is recommended to contact the rental company for more information on the insurance coverage included in the rental price.

Crossing borders with a rental car from Paraná depends on the rental company's policies.
