How to Delete All Your iPhone Contacts at Once

The fastest way to remove all contacts from your iPhone

You can delete all your iPhone contacts in one action through the Settings app — you do not have to remove them one by one. The method depends on whether you want to erase contacts stored on your phone itself or contacts synced from iCloud, and whether you want to keep a backup first.

The most common reason to do this is before selling or giving away your phone, or to start fresh after switching from another phone. If you are moving to a new iPhone, Apple's setup process will let you restore your contacts from a backup, so deleting them from the old phone does not mean losing them permanently.

Key Takeaways

Contacts stored in iCloud can be deleted through Settings > [Your Name] > iCloud, then toggling Contacts off and choosing to delete from iPhone.
Contacts stored only on your phone (not synced to iCloud) must be deleted through the Contacts app by selecting all and deleting, or by erasing the phone entirely through Settings > General > Transfer or Reset.
Before deleting all contacts, back up your iPhone through iCloud or a computer so you can restore them later if needed.
If your contacts are synced to Gmail, Outlook, or another service, deleting them from your iPhone will not remove them from that service unless you delete them there too.

Delete iCloud contacts through Settings

If your contacts are synced to iCloud (the default for most iPhone users), the quickest removal method is through Settings. Open Settings, tap your name at the top, then tap iCloud. Scroll down to find Contacts and toggle it off. Your phone will ask whether to keep or delete the contacts on your iPhone — choose Delete from iPhone.

This removes all iCloud-synced contacts from your phone but does not delete them from iCloud itself or from other devices signed into the same Apple ID. If you want to remove them from iCloud permanently, you would need to sign into iCloud.com on a computer, go to Contacts, select all, and delete them there as well.

This method is safest if you are keeping your iPhone but just want to clear out old contacts. The contacts remain in iCloud until you actively delete them from the web, so you can restore them later if you change your mind.

Delete contacts stored only on your iPhone

Contacts that were never synced to iCloud or that came from a SIM card are stored only on your phone. To remove these, open the Contacts app, tap Groups in the top left (if you see it), make sure all groups are selected, then tap Edit in the top right. Tap Select All if that option appears, then tap Delete.

Not all iPhone models show a Select All button in the Contacts app. If yours does not, you will need to delete contacts individually by opening each one, tapping Edit, scrolling to the bottom, and tapping Delete Contact. This is slower but necessary if the bulk delete option is not available on your phone.

After deleting, check your iCloud settings to confirm whether Contacts is still toggled on. If it is, any contacts you deleted from your phone will also disappear from iCloud and any other device using that Apple ID.

Erase all contacts by resetting your iPhone

If you want to remove all contacts along with all other data on your phone, you can erase the entire device. Go to Settings > General > Transfer or Reset, then tap Erase All Content and Settings. Your phone will ask for your Apple ID password and will take several minutes to complete.

This method removes everything — contacts, photos, messages, apps, and settings — and returns your iPhone to factory condition. Use this if you are selling or giving away your phone and want to ensure no personal data remains. After erasing, the phone will restart and walk you through setup as if it were brand new.

Before erasing, make sure you have backed up your phone to iCloud or a computer if there is anything you might want later. Once the erase is complete, you cannot recover data unless you have a backup to restore from.

Back up your contacts before deleting

If you think you might need your contacts later, create a backup before deleting them. The easiest method is to make sure iCloud Backup is turned on: go to Settings > [Your Name] > iCloud > iCloud Backup and toggle it on. Your phone will back up automatically when plugged in, locked, and on Wi-Fi.

You can also back up to a computer using a Mac with Finder or a Windows PC with iTunes. Connect your iPhone, open Finder or iTunes, select your phone, and click Back Up Now. This creates a complete backup of your phone including all contacts.

After you delete your contacts, you can restore them from a backup by going through iPhone setup and choosing Restore from iCloud Backup or Restore from Computer. The backup will restore your phone to the state it was in when the backup was made, including all contacts that existed at that time.

What happens to contacts synced with Gmail or Outlook

If your contacts are synced to Gmail, Outlook, or another email service through your iPhone's Mail settings, deleting them from your iPhone does not automatically remove them from that service. The contacts remain in Gmail or Outlook until you delete them there separately.

To remove synced contacts from these services, you would need to sign into Gmail, Outlook, or the other service on a computer or through its app, find your contacts, and delete them there. Check which services your contacts are synced to by going to Settings > Mail > Accounts and reviewing which accounts have Contacts toggled on.

If you want to delete contacts from your iPhone but keep them in Gmail or Outlook, turn off contact syncing for that account in Settings > Mail > Accounts, select the account, and toggle Contacts off. Choose Keep on My iPhone when prompted, then delete the contacts manually through the Contacts app.

Frequently Asked Questions

Will deleting contacts from my iPhone delete them from my other Apple devices?

Yes, if your contacts are synced to iCloud. Deleting them from your iPhone will remove them from your iPad, Mac, and any other device signed into the same Apple ID. If you want to keep contacts on other devices, turn off iCloud Contacts on your iPhone before deleting.

Can I undo deleting all my contacts?

Only if you have a backup. If you backed up your iPhone to iCloud or a computer before deleting, you can restore from that backup to get your contacts back. Without a backup, deleted contacts cannot be recovered.

What if I only want to delete some contacts, not all?

Open the Contacts app, find the contact you want to remove, tap Edit, scroll to the bottom, and tap Delete Contact. Repeat for each contact you want to remove. There is no bulk delete option for selected individual contacts in the Contacts app.

Do I need to delete contacts before selling my iPhone?

You should erase your entire iPhone using Settings > General > Transfer or Reset > Erase All Content and Settings. This removes all personal data, not just contacts, and returns the phone to factory condition. Deleting contacts alone leaves other personal information on the device.

Will my contacts come back if I restore from a backup after erasing?

Yes. If you erase your iPhone and then restore from an iCloud or computer backup, all contacts that were in that backup will be restored. If you do not want contacts restored, you would need to delete them from the backup before restoring, which is not possible with iCloud backups — you can only restore the entire backup or not at all.
