Can I actually hide my phone number on WhatsApp?
Not from anyone who already has it. WhatsApp accounts are built around your phone number as the account identity, and there is no in-app switch that removes your number from view for a contact who already has it stored on their phone. If it's worth being upfront about anything on this page, it's that: any guide claiming a full "hide my number" toggle is overstating what WhatsApp offers.
What does exist, and is worth using if strangers seeing your number is the concern, is a username. Set one up under your profile settings, and people who don't already have your number saved will see your username instead of your number by default — in new individual chats, in groups, and in calls. Creating a username also removes your number from view in existing conversations with people who never had it saved as a contact. It changes nothing for people who already saved your number before you set the username.
How do I control who sees my Last Seen, profile photo, and About?
Go to Settings > Privacy. For Last Seen & Online, Profile Photo, About, and Status, you can set each to Everyone, My Contacts, My Contacts Except… (exclude specific people), or Nobody. These settings control visibility of that specific piece of information, not your phone number itself — someone can still have your number saved and message you even with every one of these set to Nobody.
There's also a group-specific privacy control: Settings > Privacy > Groups lets you choose who can add you to a group without your approval — Everyone, My Contacts, or My Contacts Except… People outside that allowed list have to send you a private invite instead, which you have three days to accept.
How do I lock a WhatsApp chat?
- Open the individual or group chat you want to lock.
- Tap the contact's name or the group's name at the top of the chat to open its info screen.
- Tap Chat Lock and turn it on.
A locked chat moves out of your main chat list into a separate locked folder, which itself needs your phone's fingerprint, face unlock, or passcode to open. Locked chats also get quieter notifications by default — the sender's name and message preview are hidden, so a glance at your lock screen or notification shade doesn't reveal who messaged you or what they said.
To see and manage everything you've locked, or adjust default settings for locked chats, go to Settings > Chats > Chat Lock. To remove the lock from a specific chat later, repeat the same steps and toggle Chat Lock back off.
Why use Chat Lock instead of just locking the whole phone?
A phone lock protects everything on the device the same way. Chat Lock adds a second, chat-specific layer, useful if you hand your unlocked phone to someone else briefly, share a phone with family, or simply want a handful of specific conversations to require deliberate re-authentication even after the phone itself is unlocked. It's a narrower, additional control, not a replacement for keeping your phone's own lock screen enabled.

Can I stop someone who already has my number saved from seeing it?
No. WhatsApp has no setting that hides your phone number from someone who already has it stored as a contact.
Does creating a WhatsApp username hide my number completely?
No, only partially. It hides your number from people who don't already have it saved, in new chats and groups. It does nothing for contacts who already have your number.
Will locked chat notifications still show the message content?
No. WhatsApp hides the sender's name and message preview in notifications for locked chats, so the content stays private even if your notifications are visible to someone else.
