From phone numbers to usernames: WhatsApp testing new identity system

WhatsApp is gearing up to unveil a highly anticipated update that will enable users to adopt usernames, shifting away from its traditional phone number-based identification system. Since its inception in 2009, the Meta-owned messaging application has relied exclusively on mobile numbers for registration and contact discovery. This approach has begun to feel outdated, especially when compared to competitors like Telegram, which has successfully implemented usernames for several years. Recent test builds of the app have revealed references to usernames and associated rules. According to WABetaInfo, usernames must include at least one letter and can comprise only lowercase letters, numbers, periods, and underscores. Notably, attempts to register usernames that begin with 'www.' will be prohibited in order to avoid confusion with web links or official sites. Additionally, usernames formed solely of numbers or symbols will not be permitted, promoting greater clarity and consistency. Moreover, WhatsApp is reportedly testing a reservation system that will enable users to claim their preferred username ahead of the feature's public launch. This option, found in the app’s settings, aims to mitigate impersonation risks and provide early adopters with a better chance of securing their desired identity. While Meta has yet to announce a definitive timeline for the broader rollout of this feature, the introduction of the reservation mechanism suggests that this long-requested enhancement may be closer than anticipated. This change represents a significant transformation in how users connect through the world’s leading messaging service. In addition to the username feature, WhatsApp recently confirmed the integration of a built-in translation tool, allowing users to translate chats instantly without exiting the app. This feature will be rolled out across both iOS and Android platforms and is set to be available in all 180 regions where WhatsApp operates. Currently, the Android version supports six languages: English, Spanish, Hindi, Portuguese, Russian, and Arabic. Meanwhile, iPhone users will benefit from a broader selection, featuring over 19 languages through integration with Apple’s Translate app.
