WhatsApp adds username reservations

WhatsApp has long been built around phone numbers. Usernames could make the platform feel a little more private and a little less tied to your SIM card.

What happened

WhatsApp is letting users reserve usernames ahead of a broader rollout later this year.

Usernames will let people share their profile without revealing their phone number. Names can be between 3 and 35 characters.

Why it matters

This is a consumer privacy and messaging-platform signal. Phone numbers are personal, persistent and often difficult to change, which makes them a sensitive identity layer.

Adding usernames gives WhatsApp a more flexible model, closer to what users already expect from other messaging and social apps.

The bigger picture

Messaging platforms are slowly shifting from pure contact-book utilities into broader social and identity systems. Privacy, discoverability and account portability are becoming more important product questions.

WhatsApp’s move suggests even the biggest phone-number-first apps are rethinking how people should be found and contacted online.
