Merging calls on iPhone creates a conference call with multiple people on one line

When you're on a call with one person and another call comes in, your iPhone lets you connect both calls into a single conversation. This is called merging calls or creating a conference call. The process takes about 10 seconds and works on any iPhone model with iOS 13 or later.

The key is that you need to have one call already active and a second call waiting or incoming. You cannot start a merged call from scratch — you build it by combining calls that are already happening. Once merged, all parties can hear each other, and you stay in control of the conversation.

Key Takeaways

  • You must have one active call and either accept an incoming call or dial a second number while the first call is on hold.
  • Tap "Merge Calls" on the call screen to combine two active calls into one conversation.
  • You can merge up to five calls at once on most iPhones, though this depends on your carrier.
  • If you need to speak privately with one person during a merged call, tap "Private" to put the others on hold temporarily.
  • Ending the call disconnects everyone at once — there is no way to drop individual people from a merged call.

Merge two calls that are already connected

Start with one person on the line. When a second call comes in, you'll see the incoming call notification on your screen. Tap "Accept" to answer the second call. Your first caller will automatically go on hold.

Once you have both calls active, look at the bottom of your screen. You'll see a button labeled "Merge Calls" — it's usually in the center area near the keypad and speaker icons. Tap it. The two calls combine into one conversation, and both people can now hear each other and you.

Start a merged call by dialing while already on a call

If you want to add someone to a call before they call you, start with your first caller on the line. Tap the "Add Call" button — it looks like a plus sign in a circle and sits near the bottom of the screen. This puts your current caller on hold and opens the keypad.

Dial the second person's number or tap a contact to call them. Once they answer, you'll have both calls active again. Tap "Merge Calls" to combine them. If you change your mind and want to hang up on the second person instead, tap "End Call" before merging.

Add more than two people to a merged call

After you've merged two calls, you can add a third, fourth, or even fifth person using the same method. While the merged call is active, tap "Add Call" again. This puts everyone on hold while you dial or call the next person.

Once the new person answers, tap "Merge Calls" again. They join the existing conversation. Repeat this process for each additional person you want to add. Keep in mind that some carriers limit conference calls to three or four people, so check with your provider if you're trying to add more than four participants.

Speak privately with one person during a merged call

If you're in a merged call and need to talk to just one person without the others hearing, tap "Private" next to that person's name. Everyone else goes on hold, and you can speak with them alone. When you're done, tap "Merge Calls" again to bring everyone back into the conversation.

This is useful if someone asks a question you need to answer privately, or if you need to give one person different information than the group. The people on hold cannot hear your private conversation, and they won't know you've switched to private mode.

Separate calls if you need to speak with one person alone

If you want to end the merged call but keep talking to one specific person, tap "Private" next to their name first. Then tap "End Call" on the other person's line. This disconnects them from the conversation while you stay on the line with the person you selected.

The person you ended the call with will hear the line go dead. The person still on the line with you won't know anyone else was there. This is different from merging — you're actually disconnecting one person rather than just muting them.

Troubleshoot if the Merge Calls button doesn't appear

The "Merge Calls" button only shows up when you have two active calls at the same time. If you don't see it, check that you actually have two calls connected. One call on hold and one active is the minimum requirement.

If one of your calls dropped, you'll only see one active call and the button won't appear. Hang up and try again. Also confirm that your carrier supports conference calling — most do, but some prepaid plans or international carriers may not. Contact your carrier if you consistently cannot merge calls even when two are active.

Make sure you're running iOS 13 or later. Older iPhone models with earlier iOS versions don't have the merge feature. Go to Settings > General > Software Update to check your current version and update if needed.

Frequently Asked Questions

Can I merge calls on speakerphone?

Yes. Whether you use speakerphone, the earpiece, or a Bluetooth headset doesn't affect merging. Tap "Merge Calls" the same way regardless of which audio output you're using. All parties will hear each other through whatever speaker or headset you have active.

What happens when I end a merged call?

Ending a merged call disconnects everyone at once. There's no way to drop just one person while keeping the others on the line. If you need to disconnect one person but keep others, use the "Private" feature first, then end that individual call.

Do I need a special plan to merge calls?

Most carriers include conference calling at no extra cost. However, some prepaid plans or international carriers may not support it. If you're unsure, contact your carrier to confirm conference calling is available on your plan.

Can the other people see each other's phone numbers?

No. People in a merged call can only hear each other — they cannot see caller ID information or phone numbers of the other participants. They only know who is on the call if you tell them.

What if someone hangs up during a merged call?

If one person ends their call, the merged call continues with the remaining people. You'll hear a notification that the person has disconnected, but the conversation doesn't drop. Everyone else stays connected.
