How to set your WhatsApp username on iPhone and Android

In this step-by-step tutorial, we show you how to reserve your unique username on WhatsApp, edit it if you change your mind, and also block people from messaging you even if they have your username.

WhatsApp has started rolling out the usernames feature, which is in line with Telegram and other social media platforms.

After you set up your WhatsApp username, you can share it with a person, and they can text you, all without you having to share your mobile number with them. But note that, as of writing, WhatsApp only lets you reserve your username; features like messaging via username will be introduced later.

Note: WhatsApp doesn’t force you to reserve a username; you can choose to skip it.

Which username you can set

You have three choices when you go to set a WhatsApp username (steps below):

• Create a unique username
• Use your Instagram username as your WhatsApp username
• Use your Facebook username as your WhatsApp username

Note: Some people (especially journalists and whistleblowers) are very vocal on X about not linking their WhatsApp account to their Instagram or Facebook accounts to protect their privacy.

Which username you should set

If you’re a very private person like me, I suggest creating a super random username, like ja56794mes, instead of james_smith. Or, you can create a simple username (like james_smith) and then secure it with a key (mentioned below).

If you’re a social person, you can just use the same Instagram or Facebook username as your WhatsApp username.

Can someone impersonate you using your Instagram and Facebook usernames?

WhatsApp has carefully considered the implications before rolling out this username feature.

So, imagine your Instagram or Facebook username is iDownloadBlog, and someone else tries to act fast and snap it up for their WhatsApp account.

They won’t be able to do that because setting iDownloadBlog as their WhatsApp username will require them to log in to the iDownloadBlog Instagram or Facebook account, which they can’t do if you haven’t shared your login details with them.

Even if you don’t use your Instagram or Facebook username as your WhatsApp username and create a new WhatsApp username, your Instagram and Facebook usernames will remain blocked for others.

What about impersonation via other social media usernames?

Since the same parent company (Meta) owns Facebook, Instagram, and WhatsApp, they have been able to link all three and prevent username impersonation. However, this doesn’t apply to other social platforms like X (Twitter) or TikTok.

Somebody else can certainly use your X or other social media username as their WhatsApp username, provided it’s available and they act before you.

So, if you want your WhatsApp username to match your other (non-Meta) social media platforms, reserve it quickly before others do.

Of course, I assume WhatsApp has some usernames reserved for super famous people, and you won’t be able to grab any of them.

Reserve your WhatsApp username on iPhone or Android

1) Update WhatsApp to the latest version from the iOS App Store or Google Play Store.

2) Open WhatsApp on your iPhone or Android phone and tap ‘Reserve yours‘ in the ‘Usernames are coming soon‘ banner if you see it.

If you don’t see the above banner, open WhatsApp on your iPhone and tap You > Account.

If you’re on an Android phone, open WhatsApp, tap the three-dot icon at the top, and select Settings > Account.

3) Tap the new Username option.

4) Now, choose to create a new username or use your Instagram or Facebook username:

• If you want to use the same username as your Instagram or Facebook account, tap those buttons, link your Instagram/Facebook account to WhatsApp, and the username will be pre-filled. Just confirm, and you’re good to go.
• If you choose to create a username, search for your preferred username and, if it’s available, tap Save. Otherwise, try other usernames.

Set up a username key to add a second layer of privacy

After you reserve a username, you can choose how people contact you by username.

Your options are to let everyone who has your WhatsApp username (or who has guessed or mistyped) to text you.

The other option is more privacy-focused. It lets you set up a four-digit username key to add a barricade. Thereafter, even if someone has your WhatsApp username, they won’t be able to message you until you also share your four-digit key with them.

You can, of course, change these privacy settings later.

Edit or delete your username

You can change or delete your WhatsApp username. Just return to WhatsApp account settings > Username and tap the Edit button at the top. Then, tap Change Username or Delete Username.

If you don’t get the option to set up a username

WhatsApp is adding this feature gradually. So, wait and keep returning to WhatsApp Account settings regularly. You should get it soon.

Secondly, make sure you update the WhatsApp app on your iPhone and Android phone. Even if you installed an update recently, check the App Store or Google Play Store for a new one. Sometimes, you may even see a new update immediately after installing one.

Will spam texts increase via username?

It may. If you have a simple username like James, people can just message you like they can on every other social platform.

But just like other platforms allow you to make your account private or block incoming messages, WhatsApp gives you the unique ‘username key’ feature that blocks others from messaging you if they don’t have your four-digit key, even though they have your username (already explained above).

What do you think of the usernames feature? Will you be setting one?
