WhatsApp Usernames: Complete Guide to the New Feature (2026)

What Are WhatsApp Usernames?

WhatsApp usernames are a new way for users to identify themselves on the platform. Instead of sharing your phone number, you can now create a unique username that others can use to find and contact you.

Why this matters:

• Users control who has their phone number
• Businesses need new ways to identify customers
• Privacy-first approach aligns with modern expectations
