How to Merge Contacts: A Step-by-Step Guide

Updated · Standard formula, shown below

Duplicates in your address book waste time and can make you miss important calls or messages. This guide shows you how to merge contacts on both iPhone and Android, along with tips for keeping your list clean. You’ll need access to your phone’s contacts app and, optionally, a Google account for syncing.

What You’ll Need

  • Your smartphone (iPhone or Android) with the contacts app
  • If using an Android, a Google account (for contacts sync)
  • If using an iPhone, an iCloud account (for backup and sync)
  • Optional: A computer with a web browser for using Google Contacts or iCloud.com

Step-by-Step

On iPhone (iOS)

  1. Open the Contacts app (or the Phone app and tap the Contacts tab).
  2. Find the contact you want to merge. Tap it to open the details.
  3. Tap Edit in the top-right corner.
  4. Scroll to the bottom and tap Link Contacts…
  5. Choose the duplicate contact from the list, or search for it.
  6. Tap Link in the top-right. The contacts will be merged into one card.
  7. Tap Done to save. The two entries will now appear as one.

On Android (using Google Contacts)

  1. Open the Google Contacts app (pre-installed on most Android phones).
  2. Tap the Menu (three horizontal lines) in the top-left.
  3. Select Merge & fix. The app will automatically find duplicates.
  4. Tap Merge all to combine all suggested duplicates, or review them individually.
  5. If you want to merge manually, tap a contact, then tap the three-dot menu and choose Merge.
  6. Select the other duplicate and tap Merge.

On Google Contacts (Web)

  1. Go to contacts.google.com and sign in with your Google account.
  2. On the left, click Merge & fix.
  3. Review the suggested duplicates. Click Merge all to combine them, or select specific ones and click Merge.
  4. To manually merge, click a contact, then click the pencil icon (Edit).
  5. Click the three-dot menu and choose Merge.
  6. Select the other duplicate and click Merge.

On iCloud (Web)

  1. Go to icloud.com and sign in with your Apple ID.
  2. Open the Contacts app.
  3. Select one of the duplicate contacts by clicking it.
  4. Hold the Ctrl (Windows) or Cmd (Mac) key and click the other duplicate.
  5. Click the gear icon at the bottom-left and choose Merge.
  6. Confirm the merge. The two cards will become one.

Common Mistakes

  • Merging the wrong contacts – Always double-check names and phone numbers before merging, especially if contacts have similar names.
  • Losing important details – Some apps may discard fields that conflict. Review the merged card to ensure no important notes, emails, or addresses are lost.
  • Forgetting to sync – After merging, make sure your contacts sync to the cloud (iCloud or Google) so the changes appear on all your devices.
  • Using the wrong app – On Android, if you have contacts stored on the SIM card or a third-party app, Google Contacts may not see them. Make sure all contacts are saved to your Google account.

Tips

  • Before merging, export a backup of your contacts (via iCloud or Google Contacts settings).
  • Use the automatic merge feature on Google Contacts – it’s usually accurate and saves time.
  • If you have many duplicates, use a third-party app like Contacts Cleaner (but be cautious with privacy).
  • Regularly clean your contacts every few months to prevent a backlog.
  • When merging manually, keep the card with the most complete information as the primary one.

Troubleshooting

  • The merge option is missing – On iPhone, if you don’t see “Link Contacts,” make sure you’re editing the contact and scrolling to the bottom. On Android, ensure you’re using Google Contacts, not the default phone app.
  • Contacts reappear after merge – This usually happens due to syncing issues. Force-sync your contacts (Settings > Accounts > Sync now) and try again.
  • Merged contact loses data – If a phone number disappears, it may be because the two contacts had different labels (e.g., “mobile” vs. “work”). Check the merged card and add the missing info manually.
  • Can’t merge on iCloud – Make sure you have selected exactly two contacts. If you select more than two, the merge option may be greyed out.
  • Google contacts not showing duplicates – Try refreshing the page or app. If still not, use the manual merge method.

Frequently Asked Questions

Can I merge contacts on both iPhone and Android?

Yes, both platforms have built-in tools. iPhone uses the “Link Contacts” feature, while Android (via Google Contacts) has a “Merge & fix” tool.

Will merging contacts delete any data?

In most cases, no. The apps combine all fields from both contacts. However, if there are conflicting fields (like two different email addresses), both are usually kept, but some apps may prioritize one.

How do I merge contacts from my SIM card?

On Android, go to Settings > Contacts > Import/Export, and import SIM contacts to your phone. Then they’ll appear in Google Contacts and can be merged. On iPhone, SIM contacts are not stored separately; they’re already in the phone.

Can I undo a merge?

On Google Contacts, you can undo within a few seconds after merging (an “Undo” button appears). On iPhone, you can unlink contacts by editing the merged card and tapping “Unlink.”

Why do I have so many duplicates?

Duplicates often come from syncing multiple accounts (Google, iCloud, Exchange) or from importing contacts from different sources. Using a single primary account can reduce duplicates.

Is there a way to merge contacts automatically?

Yes, Google Contacts offers an automatic “Merge all” option. On iPhone, you need to do it manually, but third-party apps can automate the process.
