WhatsApp Is Adding Usernames to Keep Your Phone Number Private
WhatsApp is finally getting a long-awaited privacy feature that allows you to display a username rather than your phone number, which will remain hidden from other users. This feature has been in the works for more than a year, with few details released as to its functionality and ETA. While it's still not rolling out to all users just yet, we now know a little bit more about how it will work.
According to WABetaInfo (and as reported by 9to5Google), WhatsApp is set to launch usernames to a very limited number of accounts as part of a phased rollout. This means that you may not have access to this update now—but you should consider the switch as soon as it becomes available to you.
How to add a username to WhatsApp
Once the username feature is widely available, you should see the option in your WhatsApp profile settings (go to Settings and tap your profile name and photo). On the pop-up, you can choose to create a WhatsApp username or select your existing Facebook or Instagram username instead. According to WABetaInfo, WhatsApp has a handful of rules for new usernames:
Usernames can contain only lowercase letters, numerals, periods, and underscores.
Usernames must include at least one letter.
Usernames cannot start with "www." or end in a domain (such as .com).
Usernames must be be 3–35 characters in length.
Usernames on WhatsApp must also be unclaimed across other Meta platforms—so even if a username appears available on WhatsApp, you won't be able to choose it if someone else is using it on Facebook or Instagram. If you have an existing username on either of the latter, consider the potential privacy implications of making your accounts easy to identify across platforms before linking that same name to WhatsApp.
Along with a WhatsApp username, you'll also be able to set up a four-digit code, which other users will need to enter when they message you for the first time. Username keys allow you to limit communication to trusted contacts.
