Meta adds privacy without abandoning phone-based accounts.
MENLO PARK, UNITED STATES — July 2026.
WhatsApp has begun introducing usernames, a major privacy feature that will allow people to communicate without immediately revealing their telephone numbers to unfamiliar users, businesses or group participants. Meta opened the reservation process as part of a gradual global rollout expected to reach the messaging platform’s more than three billion users over the coming months. Participation will be optional, meaning people may continue using WhatsApp through their existing telephone-based identity without creating a public handle. The change addresses one of the service’s most persistent privacy concerns by separating the information needed to begin a conversation from the personal number used to register and secure an account.
Each person will be able to select a unique username that can contain a real name, professional identity, brand reference or pseudonym, provided another account has not already claimed it. WhatsApp will automatically verify availability and offer alternative suggestions when the requested identifier is unavailable, helping users avoid repeated manual searches. People who already use the same handle on Facebook or Instagram may be able to claim it on WhatsApp when ownership and eligibility requirements are satisfied. Meta is also restricting selected names associated with public institutions, companies, celebrities and political figures to reduce impersonation, fraud and the unauthorized appropriation of recognizable identities.
The username will replace the visible telephone number when a person starts communicating with someone who is not already included in the recipient’s contact list. This protection is expected to apply to individual chats, group interactions, voice calls and video calls initiated through the new identification system. Users who already possess someone’s telephone number in their address books may continue seeing that information, because the feature is designed primarily to prevent disclosure during new connections. WhatsApp accounts will still require a valid telephone number for registration and verification, so usernames will function as a privacy layer rather than eliminating the platform’s underlying phone-based architecture.
Meta has designed the system without a public directory, recommendation engine or open search tool capable of displaying every account associated with a similar name. A person attempting to make contact must know the complete and exact username, creating a barrier against mass discovery, automated profile collection and indiscriminate unsolicited messaging. This model differs from social networks where users can search partial names, browse suggested accounts and explore large databases of public profiles. WhatsApp is therefore attempting to preserve the relatively private nature of direct messaging while making it easier to connect with customers, colleagues, temporary contacts and people encountered through online communities.
An optional security key will provide an additional defense for people who want tighter control over first-time messages from unknown users. When enabled, a person seeking to initiate a conversation must possess both the correct username and the corresponding access key established by the account owner. The measure is intended to limit spam, harassment, phishing attempts and unwanted contact if a username is posted publicly, leaked through another service or discovered by an unauthorized person. Users will retain the ability to block and report suspicious accounts, while existing protections such as end-to-end encryption, two-step verification and controls for calls from unknown numbers will remain available.
The reservation process will appear gradually inside the latest version of WhatsApp, although immediate availability may vary according to operating system, country and account. Android users are expected to find the option within the account section of the application’s settings, while the iPhone interface may place it directly within the personal profile area. Reserving a username does not necessarily mean that every related communication function will become active immediately, because Meta plans to introduce the complete experience in stages. Users should therefore rely on official application notifications and avoid third-party websites claiming that they can sell, transfer or guarantee access to valuable WhatsApp usernames.
The change could be especially significant for people who use WhatsApp for sales, professional networking, neighborhood groups, online marketplaces, education and temporary service arrangements. Sharing a telephone number can expose information connected to banking alerts, identity verification, account recovery systems and other applications that use the same number as a personal identifier. A username offers greater separation between private communications and interactions with individuals who may only require temporary access to a conversation. Businesses may also benefit by promoting an identifiable handle instead of publishing staff members’ personal numbers, although organizations will still need clear verification practices to prevent customers from contacting fraudulent accounts.
WhatsApp has developed the feature for several years as competing platforms increasingly allowed communication through usernames rather than direct telephone-number exchange. Telegram has long supported public handles, while Signal introduced usernames with a privacy-focused structure that limits open account discovery and reduces exposure of registered numbers. Meta’s implementation appears closer to the restrictive model because it avoids a public directory and offers an additional access key for users seeking stronger protection. The company must nevertheless demonstrate that reserved-name protections, reporting systems and verification mechanisms can control impersonation attempts once billions of individuals and organizations begin competing for recognizable identifiers.
The new system will not make WhatsApp users completely anonymous, prevent every form of fraud or erase telephone numbers already shared with existing contacts. People must continue protecting verification codes, reviewing linked devices, activating two-step verification and treating unexpected requests for money or confidential information with caution. Username-based communication reduces unnecessary exposure, but criminals may adapt by creating misleading handles, imitating brands or persuading victims to reveal access keys through social engineering. Its effectiveness will ultimately depend on Meta’s technical safeguards and on whether users understand that concealing a telephone number is an important privacy improvement rather than a substitute for responsible digital-security practices.
