Having duplicate contacts on your iPhone can lead to confusion, clutter, and even missed calls or messages. Whether the duplicates came from syncing multiple accounts (like iCloud, Gmail, or Outlook), restoring from backup, or importing a contact list, Apple provides simple ways to merge and clean up your contact list without deleting data manually.

This guide explains how to merge duplicate contacts on your iPhone using built-in iOS tools, iCloud.com, and third-party apps, along with tips to keep your contacts list tidy in the future.
📇 Why Do Duplicate Contacts Appear?
Duplicate contacts usually occur due to one or more of the following reasons:
- Syncing contacts from multiple sources (e.g., iCloud + Gmail)
- Importing contacts from a SIM card or backup
- Using third-party messaging apps (WhatsApp, Messenger) that access your contacts
- iOS contact sync bugs after an update or restore
While these duplicates may appear harmless, they can cause issues like:
- Messages going to the wrong number
- Duplicate entries in WhatsApp or iMessage
- Confusion over which contact is current or accurate
✅ Option 1: Merge Duplicate Contacts Using iOS 16 or Later
If you have iOS 16 or newer, Apple has introduced a built-in tool to detect and merge duplicate contacts.
Steps:
- Open the Contacts app.
- At the top of the screen, if duplicates are found, you’ll see a message like:
“Duplicates Found” - Tap on View Duplicates.
- You’ll see a list of contacts that have duplicate entries.
- Tap Merge All to combine all duplicates at once.
Or tap a contact pair to review and then select Merge.
✅ This feature merges names, phone numbers, email addresses, and other fields into a single contact card.
✅ Option 2: Merge Contacts Manually on iPhone
If you’re using an older version of iOS, you can still merge contact information manually.
Steps:
- Open the Contacts app or Phone > Contacts.
- Locate one of the duplicate entries.
- Tap Edit in the top-right corner.
- Scroll down and tap Link Contacts… (you may see Add Linked Contact).
- Find the duplicate contact and tap it.
- Tap Link in the top-right corner.
- Tap Done.
This links the two contacts together. They’ll now appear as a single contact card with all the information combined.
☁️ Option 3: Merge Duplicates Using iCloud.com (Mac/PC)
If your contacts are synced with iCloud, you can use a desktop browser to manage and merge them more easily.
Steps:
- Open a browser on your Mac or PC.
- Visit https://www.icloud.comand sign in.
- Click on Contacts.
- Hold down Command (Mac) or Ctrl (Windows) and select multiple duplicate contacts.
- Click the gear icon (⚙) in the lower-left corner and select Merge.
Merged contacts will automatically sync back to your iPhone within a few minutes.
🔄 Option 4: Use Third-Party Apps to Find and Merge Duplicates
If you have a large number of contacts or want more automation, use contact management apps from the App Store.
Recommended Apps:
