How to add someone to a group chat depends on which app you're using and whether you created the group
The steps change between iMessage, WhatsApp, Facebook Messenger, and other platforms. On most apps, you open the group conversation, tap or click a menu icon, find an "Add Member" or "Add People" option, and select the person from your contacts. Some apps let any member add people; others restrict it to the group creator or admin. If you can't find the option, the group settings may have locked it down, or the app may not support adding people after the group was created.
The process usually takes under a minute once you know where to look. This guide covers the most common messaging apps and shows you exactly where to find the add button on each one.
Key Takeaways
- Most messaging apps have an "Add Member" button in the group info screen, accessed by tapping the group name or a menu icon at the top of the chat.
- iMessage, WhatsApp, and Messenger all work slightly differently — iMessage requires you to tap "Details," WhatsApp uses an info icon, and Messenger uses a plus sign or "Add People" button.
- Some groups restrict who can add members; if you don't see an add option, the group creator or admin may have turned it off.
- You can only add people who are already in your contacts or whose phone number or username you know.
Adding people on iMessage (iPhone, iPad, Mac)
Open the group conversation in Messages. Tap the group name or icon at the very top of the chat window. This opens the group details screen.
Scroll down and tap "Add Contact." A list of your contacts appears. Tap the person you want to add, then tap "Add" to confirm. You can add multiple people at once by tapping each name before confirming. Once you tap the final "Add" button, the new members receive a notification that they've been added to the group.
If you don't see an "Add Contact" button, the group creator may have restricted who can add members. On some older iOS versions, this option appears as "Details" instead of the group name — tap that first, then look for "Add Contact."
Adding people on WhatsApp (Android, iPhone)
Open the group chat. Tap the three dots (Android) or the group name (iPhone) at the top. On Android, select "Group Info." On iPhone, you're already in the group info screen.
Look for "Add Participants" or a plus icon next to the member list. Tap it. Your contacts list appears. Select the person or people you want to add by tapping their names — a checkmark appears next to each one. Tap "Add" or the checkmark icon to finish.
WhatsApp shows you a notification in the chat saying "[Your name] added [new member]." The new member can see the full chat history from before they joined, so they won't miss context.
Adding people on Facebook Messenger (Android, iPhone, web)
Open the group conversation. Tap the group name at the top (mobile) or look for a group info icon (web). On the web, click the "i" icon in the top right corner of the chat.
Look for a plus sign or "Add People" button near the member list. Tap or click it. Search for the person by name or username, or scroll through your recent contacts. Tap their name to add them. You can add multiple people before closing the menu.
On the web version, you may see "Add Members" as a button in the group details panel on the right side of the screen. The process is the same: click it, search for names, and confirm.
Adding people on Google Messages (Android)
Open the group conversation. Tap the group name at the top to open group details. Tap "Members" or scroll to the member list. Look for a plus icon or "Add Members" button.
Tap it and select people from your contacts. You can add one person or several at once. Tap "Done" or "Add" to confirm. The new members see a notification that they've been added to the group.
What to do if you can't find the add option
If the add button is missing, the group creator or an admin has likely restricted who can add members. In WhatsApp and Messenger, group admins can turn off the ability for regular members to add people. Only the admin can add new members in this case.
Ask the group creator or admin to add the person for you. If you're the creator and still don't see the option, check that you're in the group info screen (not just the chat) and that the app is fully updated. Restart the app or your phone if the button still doesn't appear.
Some very old group chats on older app versions may not support adding people after creation. If the group was made years ago and the feature never worked, creating a new group and inviting everyone fresh is usually faster than troubleshooting.
Adding people on Telegram (Android, iPhone, web)
Open the group chat. Tap the group name at the top to open group details. Scroll down to the member list. Tap "Add Member" or the plus icon.
Search for the person by username or phone number, or select from your contacts. Tap their name to add them. Telegram lets you add multiple people at once. Tap "Done" when finished.
If the group is a supergroup or channel, only admins can add members. If you're not an admin and don't see the add option, ask the group creator to add the person for you.
Frequently Asked Questions
Can I add someone to a group chat if I don't have their phone number?
It depends on the app. WhatsApp and iMessage require a phone number or contact. Messenger, Telegram, and Google Messages let you search by username or name if the person has set up a public profile. If they're not in your contacts and have no public profile, you'll need to ask them for their phone number or username first.
What happens when you add someone to a group chat?
The new member gets a notification that they've been added. On most apps, they can see the full chat history from before they joined. Some apps (like older versions of WhatsApp) only show messages sent after they joined. Either way, they're now part of the group and can send and receive messages.
Can I remove someone from a group chat after adding them?
Yes. Open the group info, find the member's name, and look for a remove or delete icon (usually an X or trash can). Tap it to remove them. Only admins or the group creator can remove members in most apps, though some let any member remove themselves.
Why does the add button look different on my phone than the screenshots I found?
App layouts change with updates, and they differ between Android and iPhone. The button might say "Add Members," "Add Participants," "Add Contact," or show as a plus icon. Look for any of these near the member list in the group info screen. If you're still stuck, restart the app or check that it's fully updated.
Can I add someone to a group chat if they blocked me?
No. If someone has blocked you, you can't add them to a group, and they won't receive the notification if you try. They would need to unblock you first. Some apps (like Messenger) may not show an error message — the add just silently fails.
