If you’d like to give backers the option to update their delivery address before you start shipping rewards, select this option on the ‘Reward surveys’ page. Alternatively, if you decide to add this functionality after you’ve already sent out your surveys, select the “Edit” option next to “Address changes not allowed" on the same page.
If you’re ready to ship out rewards and you no longer want to allow delivery address changes, head back to the ‘Reward surveys’ page, select “Edit” next to “Address changes allowed” and click “Disallow changes”. A modal will appear asking you to confirm this change. Once you select “Send notifications now,” backers will be notified that they have 48 hours to finalize any changes to their shipping information before the survey is locked.
Backers can't directly update responses to other survey questions (for example, reward size, color, etc.) but if someone contacts you with an important edit you can leave a note on their pledge in your backer report.
Can backers change their shipping country?
No, backers cannot change their shipping country after the project has ended. If the incorrect shipping fee was collected due to an incorrect country/region selection, you will need to work with the backer directly to find a solution outside of Kickstarter.
