WhatsApp's newly introduced username feature has ignited a heated debate, fueled by claims that it hides a user's phone number and displays only the username.

The concern is particularly acute for businesses operating on the Meta-owned messaging platform. Beyond maintaining a presence in the app, business owners generally need their phone numbers visible to customers, especially when they are not available on WhatsApp and customers still need a way to get in touch.

Fearing the loss of customer reach on the platform, some businesses have started deleting their usernames — the feature is optional — and non-business users have taken similar steps.

The feature, announced in June, allows users to chat and connect on WhatsApp without sharing their phone numbers. In explaining how it works, Meta noted that phone numbers are hidden upon initial contact when a username is in use. The company has framed usernames as part of a broader push to tighten security across the platform.

“WhatsApp is introducing usernames, a major privacy feature designed to help you connect with new people without giving away your phone number,” Meta said in a blog post.

The feature is aimed chiefly at keeping users' phone numbers from being saved when they join public groups. Someone who wants to join a football banter group, for example, but is not ready to expose their number to people they do not know or have never met can rely on a username instead.

Phone numbers are tied to a person's real identity, making them a sensitive piece of personal information to hand out. Usernames remove that requirement entirely, allowing people to connect on their own terms while keeping their number private. This form of identity protection is already familiar to users of platforms such as Telegram and Signal, both of which have offered the capability for some time.

Reservations for usernames are open to WhatsApp's more than three billion users globally, and Meta plans to activate the feature before the end of 2026. Reservations opened with the June announcement, letting users claim a preferred handle ahead of the feature's activation. Usernames remain an optional setting for all users. With activation still pending, both the reservation period and the deletions are unfolding ahead of rollout — leaving the practical balance between privacy and reachability to be tested once usernames go live.

Amid the debate, some viral claims deserve clarification. WhatsApp introduced the username feature to stop random people from accessing your phone number, making it the platform's biggest privacy feature in years. But while a username changes how people find you on WhatsApp, setting one up does not disable your phone number, turn off traditional WhatsApp messaging, or stop your phone calls. Your number remains tied to your underlying account, and only existing contacts — or anyone who has your number saved — can call or message you as usual.

Meta offered further clarification in its blog post: “Once we launch usernames, when you message a person or business for the first time, they will no longer see your phone number if you enabled your username.”

For business owners on WhatsApp, the fear of becoming unreachable while offline is nonetheless real. If a customer dials a merchant's regular phone number in a direct mobile (GSM) call, but the merchant relies exclusively on a WhatsApp username when online, customers who lack the phone number cannot reach the business through traditional phone lines or SMS. WhatsApp messages and calls also require an active internet connection over Wi-Fi or cellular data; if a business's mobile data is switched off, a customer relying solely on its username cannot get through until it comes back online.

Meanwhile, businesses that already use a recognizable username on X (Twitter) or Instagram can improve their chances of maintaining search visibility by retaining the same username on WhatsApp. The consistency preserves their popularity and allows new users arriving from those social platforms to easily search for and locate their presence.
