WhatsApp to introduce usernames and business-scoped user IDs in 2026
WhatsApp will allow users to communicate via usernames instead of phone numbers, with rollout expected throughout 2026. Businesses using WhatsApp API must update CRM systems, chatbots, and workflows to support the new Business-Scoped User ID (BSUID) by June 2026.
Why it matters for advertisers
For you, this means WhatsApp campaigns may experience reduced friction, as users can contact businesses without sharing their phone numbers, potentially improving CTR on click-to-WhatsApp ads.
