Beginning next year, WhatsApp will start to support usernames, moving away from its exclusive use of phone numbers. This upgrade, communicated to businesses, details the implementation timetable and technical transition strategy.
### Business-Scoped User IDs
Recently, Meta has been gearing up for the introduction of username support on WhatsApp. This includes a system for reserving usernames that will be accessible prior to the complete feature rollout. In a document shared with business partners, Meta highlighted the rollout strategies and technical prerequisites for this new functionality.
The rollout will present a Business-Scoped User ID (BSUID), a distinct identifier allocated to each WhatsApp user. This enables businesses to message users even if their phone number is not available. The BSUID will be connected to the user_id parameter and incorporated into all message webhooks, guaranteeing that businesses can securely engage with users while complying with privacy and data protection regulations.
The BSUID aims to deliver a reliable and privacy-focused method for businesses to identify and assist customers who choose usernames over phone numbers. This identifier will feature in WhatsApp’s webhook alerts and be supported in both existing and forthcoming API versions. Developers must update their systems to ensure smooth message routing, customer records, and automated replies.
Meta envisions a future where businesses can communicate with customers purely through usernames, removing the necessity for personal contact information.
### Timeline Details
Meta has released a schedule for the launch of username support. Businesses have until June 2026 to implement the necessary technical changes to adopt BSUIDs. This implies that the rollout may take place shortly after this deadline, with the username reservation system probably launching in the first half of the year, enabling users to secure their preferred usernames.
In conclusion, the introduction of usernames on WhatsApp signifies a considerable change in how users can engage with the platform, improving privacy and offering businesses innovative ways to connect with customers.
