How to Reserve Your WhatsApp Username: Rules, Username Key and Safety Tips

For the first time, you can chat on WhatsApp without giving people your phone number. WhatsApp is rolling out usernames worldwide, and many people are now searching for how to reserve their name before someone else takes it. This guide explains how a WhatsApp username works, how to reserve one, the rules for choosing a name, what the optional username key does and how to stay safe as the feature spreads.

What are WhatsApp usernames?

Until now, everyone on WhatsApp was identified by a phone number. To chat with someone, you needed their number, and they could see yours. Usernames change that. You can now share a name like @adaeze.designs instead of your number when you meet new people.

WhatsApp announced the feature on 29 June 2026 and began letting people reserve names that week. The full rollout is happening in phases over the following months, with global availability planned. A phone number is still required to create and keep a WhatsApp account; the username is simply an extra way to be found.

Why usernames matter

• Privacy. You can join community chats, sell online or talk to new contacts without exposing your number.
• Safety. Fewer people holding your number means fewer chances of spam calls and SIM-related fraud.
• Branding. Creators and businesses can use the same name they use on Instagram and Facebook.
• Convenience. A short, memorable name is easier to share on a flyer or in a video than a long number.

How to reserve a WhatsApp username

1. Update WhatsApp from the Play Store or App Store.
2. Open the app and go to Settings.
3. Tap your profile (your name and photo).
4. Look for the Username option. If you see it, tap it.
5. Type the WhatsApp username you want and check whether it is available.
6. Save your choice.

The option is available in the mobile app first, not on WhatsApp Web or the desktop app. If you cannot see it yet, WhatsApp says to keep the app updated and wait, because accounts are being enabled in stages. You will get a notification when the feature reaches you.

Rules for choosing a username

• Length: up to 35 characters, with reports citing a minimum of three.
• Optional: you do not have to create one. Your number still works as before.
• Changeable: you can change or remove your username at any time.
• Reserved names: usernames linked to well-known public figures, government officials and celebrities are protected and not available to others.

Pick a WhatsApp username that is simple and that you will not regret. Avoid your date of birth, phone number or other personal details, since scammers can use them to guess passwords and security answers.

What is the username key?

The username key is an optional short number that you can add to your username. When you turn it on, people need both your username and the key to message you for the first time.

Think of it like a door code. Your username tells people which door is yours, and the key lets in only those you have given the code. It is a strong option for anyone who receives a lot of unwanted messages.

WhatsApp has also said there will be no public directory or search suggestions for usernames, which makes it harder for strangers to browse for people.

Claiming your Instagram or Facebook name

Creators, businesses and organisations can claim usernames that match their existing Instagram or Facebook identities. Other users who want the same name across Meta’s apps can link their accounts through Meta’s Accounts Center. This helps prevent impersonation, because a fake account cannot easily grab a well-known brand’s name on WhatsApp.

Stay safe as usernames roll out

New features always attract scammers. Some security experts worry that anonymous usernames could help fraudsters hide. Protect yourself with these habits:

• Ignore “reserve your username” links. You reserve a name inside the WhatsApp app only. Any website or message offering to do it for you is a scam.
• Never share your six-digit WhatsApp code. Anyone who has it can take over your account.
• Turn on two-step verification. Follow our WhatsApp two-step verification guide.
• Use the username key if you get unwanted messages.
• Block and report suspicious accounts. These tools still work with usernames.

Scams on SMS are rising too. Read how Google is fighting them in our guide to turning on scam protection in Google Messages.

Tips for small businesses

• Reserve your brand name as your WhatsApp username as soon as the option appears.
• Use the same handle you use on Instagram so customers recognise you.
• Add your username to flyers, packaging and your link in bio.
• Keep a separate business number with WhatsApp Business if you handle many orders.
