How to Delete All Contacts on iPhone At Once

Your iPhone, by default, would only let you delete contacts from your contact book, one at a time. Although this will work for a few contacts, it is still unpleasant for those who would like to delete a large number of contacts. One of the ways to go through the process would be to delete them via iCloud. If you don’t want to go in this way, there’s an even easier way of doing it –using an app from AppStore.

This post will feature both ways of deleting multiple numbers so that you may choose for yourself what is good for you. All these methods work perfectly and your choice should only depend on the ease of use and availably of the right software.

How to Delete Multiple Contacts from the iPhone Using Groups App

The Groups App is a third-party application that you can find on the Apple AppStore. It is available for download free-of-charge and allows you to perform collective actions on a group of numbers. The following procedure will help you delete multiple contacts from the iPhone 6.

  • Open AppStore and find Groups App
  • Install and launch the app
  • Grant it access to your contacts
  • Select All Contacts from the Groups List
  • Scroll through the contacts and mark those you would like to delete
  • Marking can be done by clicking on circle outline, located on the left of the name
  • Select choose action at the top bar after you’ve finished marking
  • Find and tap on Delete Contacts on the popup menu
  • Select Remove from my iPhone! to confirm your action

That’s all you need to do when using the Groups App, and you’ll have deleted all saved numbers from your iPhone.


Once you have deleted the numbers you can now go back to the groups app to confirm whether you’ve actually completed the process. The iCloud option might take you a lot of time but does work well, while the Groups App isn’t the most user-friendly app around, but still can perform a better job.
