What is WhatsApp’s new username based privacy feature, expected to roll out later in 2026, how can users and businesses reserve first come first served usernames while continuing to use phone numbers if they choose, why has WhatsApp locked down the names and lookalike variations

Safeguards WhatsApp says it will use

• Phone-number privacy: A username can be shared instead of a phone number, reducing the routine exposure of a number to strangers, customers, sellers, creators or groups. It does not eliminate the number from WhatsApp: every account remains tied to a verified number.
• No open discovery directory: Usernames are not intended to be publicly searchable or algorithmically suggested. A would-be contact needs the exact handle before attempting contact.
• Username keys: Users can optionally add a separate username key. In effect, knowing the username alone would not be enough to message them; the sender would also need that key.
• First-contact warnings and controls: WhatsApp says recipients will receive contextual safety information for first-time username contacts, including country and account details, and can block or report unwanted messages.
• Platform enforcement: WhatsApp says it will use suspicious-account detection and limits on outreach/contact attempts to curb bulk messaging and abuse. These measures can reduce scale, but their effectiveness will depend on enforcement quality and how quickly abusive accounts are detected.

Benefits, limits and continuing scam risk

• Privacy and security commentators broadly see a real benefit: decoupling a public contact identity from a personal phone number can reduce unwanted calls, SIM-targeting opportunities and the collection of numbers from public-facing business or social interactions.
• But a username is not proof of identity. Scammers can use convincing near-matches, stolen profile photos, compromised accounts, social engineering or links sent from apparently plausible handles. Reserving a small set of high-profile names does not solve impersonation of ordinary people, local businesses, relatives or officials whose names are not protected.
• Phone-number exposure also remains possible when people deliberately share it, are already connected through contacts or groups, use existing number-based chats, or interact through services that still display it. The feature is therefore privacy-enhancing, not anonymity.
• The practical defence remains public awareness: do not act on a message solely because of its handle or display name; independently verify requests for money, credentials, OTPs or urgent action through a known official channel; and block and report suspicious accounts.

India’s objection

India’s IT ministry asked WhatsApp to pause the rollout in India pending consultations and a detailed explanation of how the system would prevent misuse. Its central concern was that pseudonymous handles could make phishing, impersonation and fraud harder to attribute and investigate, despite the potential privacy gain.

WhatsApp’s response has been that usernames are optional, accounts still require verified numbers, and the system will include the safeguards above. The disagreement highlights the core trade-off: less routine exposure of ordinary users’ phone numbers versus a new, potentially easier-to-brand channel for deception.
