WhatsApp is poised to transform digital communication with its long-awaited username feature, allowing users to connect without sharing phone numbers. First spotted in beta versions in 2023, the feature has advanced significantly, with recent TestFlight beta updates revealing a refined interface for creating unique usernames.
This development introduces robust privacy controls, including a PIN protection system, to safeguard users from spam and unwanted contact. As WhatsApp nears a public rollout, this feature promises to enhance security and personalization, aligning the platform with competitors like Telegram and Signal.
Enhanced Privacy with Username Options
The username feature offers three privacy settings to give users control over their visibility: "Username," "Phone number," or "Username with PIN." The "Username" option hides phone numbers from new contacts, while existing contacts with saved numbers retain access. For added security, the "Username with PIN" setting requires new contacts to enter a four-digit PIN, reducing the risk of spam or scams.
WhatsApp promotes this feature through informational banners in the Chats tab, encouraging users to enable PIN protection. This approach is particularly beneficial for professionals and online sellers who wish to maintain accessibility without exposing personal contact details.

PIN Protection: A New Security Layer
The PIN protection system is a standout feature, distinct from WhatsApp’s six-digit two-step verification PIN used for account access. The username PIN, a four-digit code, ensures only those with the correct PIN can initiate chats via a username, offering a robust defense against unauthorized messages.
Recent beta updates for Android (version 2.24.18.2) highlight WhatsApp’s focus on refining this system, with real-time username availability checks displaying green checkmarks for available names and red warnings for taken ones. This dual-PIN strategy underscores WhatsApp’s commitment to comprehensive user security across its 2 billion-plus user base.
Username Formatting and Restrictions
WhatsApp’s usernames adhere to strict guidelines to ensure security and clarity. Usernames can include lowercase letters, numbers, periods, and underscores, but cannot start with "www," end with domain names, or exceed 30 characters. They must contain at least one letter and cannot begin or end with periods to prevent phishing attempts.
Unlike WhatsApp Business display names, which follow stricter branding rules, usernames are unique identifiers that allow flexible personalization. Real-time updates indicate WhatsApp is testing these restrictions rigorously to prevent duplication and maintain a seamless user experience.
Did You Know?
WhatsApp’s end-to-end encryption, applied to both phone number and username-initiated chats, ensures that only the sender and recipient can read messages, a feature trusted by over 2 billion users globally.
Development Timeline and Rollout
The username feature has been in development since May 2023, first appearing in Android beta version 2.23.11.15. Throughout 2024, WhatsApp refined the feature across Android, iOS, and web platforms, with significant progress in July 2024 for WhatsApp Web and May 2025 for iOS beta builds.
Industry reports suggest a public release may occur in Q3 or Q4 2025, following Meta's typical 3- to 9- month beta-to-public rollout timeline. The feature’s appearance in WhatsApp Web’s latest interface updates signals that web users may gain access first, with mobile platforms to follow after extensive testing ensures stability and security.
