Can one WhatsApp number be connected to multiple Business Solution Providers (BSPs)? Yes. Meta’s WhatsApp Account Model Evolution (WAME) allows businesses to associate one WhatsApp Account (WAAC) with multiple partner-specific Messaging Accounts (PMAs).<\/strong> Each connected partner can manage its own messaging operations, templates, and billing configuration while the business retains a shared phone number.<\/p>\n\n\n\n

WhatsApp has become an important communication channel for businesses managing customer inquiries, marketing campaigns, order notifications, and customer support. However, companies using multiple messaging providers have traditionally struggled to manage different communication workflows through a single business number.<\/p>\n\n\n\n

Meta’s WhatsApp Account Model Evolution, introduced in September 2026, changes this architecture. It separates phone number management from partner-specific messaging operations, giving businesses more flexibility when connecting marketing platforms, CRM systems, customer support applications, and other messaging solutions.<\/p>\n\n\n\n

Under this model, the WhatsApp Account manages the business phone number and identity, while separate Messaging Accounts manage partner-specific messaging configurations.<\/p>\n\n\n\n

In this guide, we explain how the new WhatsApp account structure works, how businesses can connect multiple BSPs, what changes for developers, and how organizations can prepare their existing WhatsApp Business API integrations.<\/p>\n\n\n\n
