If you have a public WhatsApp group it can be annoying to add each new member yourself. Fortunately, you have an alternative. WhatsApp allows you to create a shareable link that interested participants can click to instantly join your group. Here̵
Note: To access a group link, you must have administrator rights.
Open the WhatsApp app on your iPhone or Android device and select your group chat.
Then tap the name of your group at the top of the screen to visit the profile page.
Scroll down to the bottom of the page and select the “Invite via link” option.
You will find the link of your group on the next screen.
You can copy the link by tapping the ‘Copy link’ button, or you can share it directly with ‘Share link’. When you choose the latter or ‘Send link via WhatsApp’, WhatsApp will add a default invitation text for the link.
Your group’s link is public, which means you can even post it on your website or your social feeds to invite people. When someone clicks on it, they can join it without your additional approval.
There is also an option to create a QR code for your group. If you share it, anyone can scan it to join your community.
If your group’s capacity is at its maximum in the future or you think the public link is being spammed, you can reset it from the same menu using the “Reset Link” button.
Your WhatsApp group link is set to remain active indefinitely and will only expire if you manually reset it.
WhatsApp also offers the option to write this link on an NFC tag. To do this, tap the three-dot menu icon in the top right corner of the ‘Invite link’ page and select ‘Write NFC Tag’. Touch your phone to an NFC tag to start the process.
If you run a large public WhatsApp group, you should also make sure that members cannot edit details (such as name and description) with admin tools.
