The short version: the add member tag in a WhatsApp group is the small system label that tells everyone who added a new person and when, shown as a message in the chat ("X added Y") and again under that person's name in the group info screen. If someone was invited via a link rather than added directly, the group shows them as "joined using invite link" instead, and that difference matters more than most group admins realise.
What the tag looks like
Open any WhatsApp group you are in and scroll back far enough, and you will see grey system text sitting in the middle of the chat, something like "Lilach added Sarah". That line is not a notification bubble, it is a permanent record. It stays in the chat history for as long as the group exists, and anyone who scrolls can find it.
There is a second version of the same information inside the group info screen. Tap the group name at the top of the chat, scroll to the participant list, and tap on any member. Under their name you will see a line that reads "Added by [name], [date]" or "Joined using this group's invite link, [date]". That second version is the one people miss, because it is tucked away rather than sitting in the main chat feed.
The wording changes depending on how the person joined:
- Added directly by an admin: "Added by [admin name]"
- Joined via a shared invite link: "Joined using this group's invite link"
- Added via a contact who had restricted "who can add me to groups" privacy settings: they appear in the group as "invited" with a pending status, and get a private message instead of being dropped straight in
A worked example of how this plays out
Say you run a local networking group for small business owners in your town, built from a sign-up form at a market stall. You export 40 email addresses, match 28 of them to phone numbers you already have saved, and add all 28 directly to a new WhatsApp group one evening.
Twelve of those 28 have their privacy setting locked to "My Contacts" rather than "Everyone." Instead of landing straight in the group, those twelve get a private WhatsApp message from you with an invite link and a note that you tried to add them to a group. The other 16 appear instantly, each with a grey "added by you" line under the system message and in their profile inside group info.
Three days later, two of the twelve who got the private invite still have not clicked it. One person who did join via that link later leaves the group and rejoins through a friend's forwarded link, so their tag now reads "joined using this group's invite link" rather than showing your name at all. If that person later asks "who put me in this group," the tag no longer points back to you. That is a useful thing to know if you are ever asked to account for how a group was built.
Why admins should check this
Most people treat the add member tag as housekeeping noise and scroll past it. For anyone running a group for business purposes, networking, a course cohort, a client community, it is worth a real look for three reasons.
First, it is your spam trail. If a group starts filling with people you do not recognise and messages promoting unrelated products, check the tags. You will usually find one member added a dozen strangers in a short window, which tells you exactly who to remove and who else to watch.
Second, it is an accountability record for every co-admin. If you run a group with two or three admins and membership triples overnight, the tags tell you which admin did the adding, which is the only clean way to have that conversation without it turning into a guessing game.
Third, and this is the part most guides skip entirely: the tag is a public, permanent, searchable confession that you added someone without asking first. If you have ever built a WhatsApp group by adding people from a spreadsheet, an old contact list, or a stall sign-up sheet, that grey system line sits in the chat forever as proof of exactly how they ended up there. Under UK GDPR and similar data protection rules elsewhere, adding someone to a group chat using their phone number counts as processing personal data, and consent matters. The tag does not create the legal problem, your decision to add them without consent does, but the tag is what makes that decision visible to every single person in the group, including the one person who complains to Meta or to a regulator. I would rather an admin see that risk before they hit add 40 times than after someone screenshots it.
Step by step: how to check who added someone
- Open the WhatsApp group chat
- Tap the group name at the top to open group info
- Scroll to the "Participants" section
- Tap on the name of the member in question
- Read the line under their name and phone number, it will say either "Added by [name]" with a date, or "Joined using this group's invite link" with a date
- If you are an admin and the result worries you, tap their name again, select Remove from Group, and separately message the admin who added them
On both iPhone and Android the steps are identical, the only difference is the small arrow or chevron you tap to open the participant's profile.

How privacy settings change what the tag shows
Go to WhatsApp Settings, then Privacy, then Groups. You will see three options: Everyone, My Contacts, and My Contacts Except. If you set this to My Contacts, only people already saved in your phone can add you directly, everyone else has to send you a private invite link that you choose to accept. This is the single setting that decides whether you show up with a clean "added by" tag or a pending invite that you can quietly ignore.
For anyone running a business account, this setting interacts with how you manage group access overall. If you are building out a WhatsApp Business presence and want to understand the groundwork, our guide to downloading and setting up WhatsApp Business covers the account side, and our piece on how to change your WhatsApp number to a business account is worth reading before you migrate an existing personal number into a group you run for clients.
Where this fits next to other platforms
WhatsApp is not unusual in tracking this. Facebook Groups shows similar admin logs, and if you have ever wondered what running one of those groups is worth in cash terms, our breakdown of how much money a Facebook Group admin makes is a useful comparison point. The bigger lesson across both platforms is the same: if you are building any kind of private community for business reasons, treat the membership log as a permanent audit trail, not a throwaway feature. Our guide on using Facebook privacy groups safely as a business owner walks through the consent and moderation side in more depth, and most of it applies directly to WhatsApp too.

What I would do differently
If you are building a WhatsApp group from a list of numbers rather than from people who directly asked to join, send a one line message first asking if they want in, then add them, rather than adding first and explaining later. It takes an extra five minutes for a group of 30 people. It also means that if anyone ever checks the add member tag next to your name, the story it tells is one you are happy for them to read.
Frequently asked questions
Can you remove the add member tag from a WhatsApp group?
No, there is no setting to delete or hide the system message or the "added by" line in the participant profile. It is a permanent part of the group's history for as long as the group and that member both exist in it.
Does the person who added me get notified if I leave the group?
No, WhatsApp does not send the original adder a notification when someone leaves. The group chat will show a system message that the person left, visible to everyone still in the group, but no direct alert goes to whoever added them.
Why does my tag say "joined using invite link" instead of showing a name?
That happens when you join through a shared link rather than being added directly by an admin, including links forwarded to you by someone other than the original admin. It can also happen if you leave and rejoin a group through a link after initially being added directly.
Is it legal to add someone to a WhatsApp group without asking them first?
It depends on your location and what the group is for, but in the UK and EU, adding someone using their saved phone number counts as processing their personal data, and data protection rules generally expect a lawful basis such as consent for anything beyond a small personal group. For business or marketing groups, asking first is the safer route regardless of what the law technically allows.
