Duplicate name and phone numbers may be created on iPhone if you have set multiple accounts and enabled contacts for them. Additionally, importing numbers from the SIM card, Android phone, or vCard may also create duplicate entries. It is a menace to see the same name multiple times while making a call or sending a text. To address this problem, let us look at some effective ways to delete duplicate contacts on iPhone and Mac.

Before We Begin:

If you use the same Apple ID (and iCloud contacts) on Mac and iPhone, the changes will sync. Thus, when you remove Mac’s duplicates, they will automatically be removed from the iPhone and vice versa. For this, make sure ‘Contacts’ under iCloud is enabled on both devices.

On Mac: Click on the Apple Logo from the top right → System Preferences → Apple ID → iCloud → make sure Contacts is enabled.

On iPhone: Open the Settings app → your Apple ID from the top → iCloud → ensure the toggle for Contacts is on.

How to Merge Duplicate Contacts on iPhone

It is not easy to remove duplicate iPhone contacts using the inbuilt Contacts app. But there is a workaround that lets you link contacts. On the other hand, third-party iOS apps enable you to delete or merge duplicate contacts quickly. Let’s look at both methods!

Merge Contacts Using the Linked Contacts Feature

  1. Open the Contacts app. Or the Phone app and tap on Contacts.
  2. Tap on an entry that you believe is more than once.
  3. Tap on Edit.

  5. Tap to select the contact you would like to link.
  6. Tap on Link from the top right.

  7. Finally, tap on Done.

Now, those two (or more) contacts are linked together. This does not delete the other entry but adds both phone numbers under one contact.

Suppose there is a contact Donald with his home phone number 1234567, and there is another contact named Donald T with his office number 9876543. When you link them, the single entity will have both phone numbers under one contact. In your iPhone address book, you will see just one entry.

To unlink, tap on the contactEdit → Tap on the red minus icon below LINKED CONTACTS → UnlinkDone.
