The Union government has issued a notice to Meta, the parent company of WhatsApp, seeking clarification on the messaging platform’s proposed “username” feature. Officials have asked the company to respond within three days, amid concerns that the change could increase the risk of cyber fraud.

WhatsApp is preparing to allow users to communicate without sharing their mobile numbers, using a chosen username instead—especially in group chats or when contacting new people. The feature is expected to roll out by the end of this year, and the platform has reportedly encouraged users to reserve usernames in advance.

According to the report, first-time contact through usernames would require entering a unique “username key” linked to each user. While WhatsApp has said this key can be changed at any time, it has not provided additional details on how the key would be shared with someone initiating contact.

Cybersecurity experts have warned that the system could be misused by creating usernames that resemble those of celebrities, companies or trusted individuals, enabling impersonation scams. They stressed the need for strong safeguards and quick detection and removal of fake accounts.

Home Ministry officials said the legal aspects of the feature are being examined and that the government will not compromise on national security or public safety. They added that if Meta’s explanation is not satisfactory, steps could be taken to prevent the feature from being introduced.
