WhatsApp Introduces Reserved Usernames for Privacy-Focused Messaging

WhatsApp is rolling out a feature that lets users reserve usernames (3–35 characters) to message others without revealing phone numbers. Access is staged, with a notification when you can reserve, and you can set a username in Settings > Account > Username. If you have an Instagram or Facebook username, you can claim the same on WhatsApp. There is no username directory or discovery, and messages to a username require knowing the exact handle, with an optional username key for extra spam protection. The rollout will occur gradually over the coming months, and a username-enabled account won't reveal a phone number to first-time contacts.
