Amending my Reservation


Providing that another member does not have a reservation immediately after yours, you can extend your trip using the Zipcar app or by text.

Extending via the mobile app

  • Select the relevant trip on the app
  • Once selected, proceed to tap ‘view details’
  • Once you’re on the reservation screen, there is an option to ‘change reservation’ under the vehicle image. The availability bar under the vehicle name will help you determine whether it is available for the desired time
  • When your new times have been selected, please tap ‘confirm changes’; this will take you to the reservation screen where you can view your updated reservation

Extending via SMS

  • To receive text notifications, send a text to +44 762 480 2786
  • You will receive a notification to remind you of your upcoming reservation, plus a notification 30 minutes before your reservation is due to finish.
  • To extend, reply to the message in with your desired extension in the following format:

ext 30m (30 minutes)
ext 1h (1 hour)
ext 1h30 (1 hour 30 minutes) 

OR for a specific time

ext today 6pm
ext today 6:30pm
ext tomorrow 6pm


Flex reservations don’t need to be extended as they are not pre-booked. Simply drive for as long as you need to. Please note Flex vehicles can only be taken for a maximum of 48 hours.
