How many phone numbers can I connect under one BAN?

Manage up to 100 WhatsApp Numbers under a Business Account Number (BAN)

You can connect up to 100 WhatsApp phone numbers under a single Business Account Number (BAN) in the WhatsApp Business Platform. This setup is designed for large teams, multi-region operations, or brands managing multiple customer-facing lines.

Key Limits and Structure

Element	Limit / Capability
Phone numbers per BAN	Up to 100 (each must be individually onboarded and verified via FBM)
WhatsApp Business Accounts	Multiple WABAs can be created and linked under one BAN
FBM–BAN relationship	One BAN is tied to one Facebook Business Manager (FBM). A single FBM can manage multiple WABAs, all connected under the same BAN.
Messaging tiers per number	Each phone number has its own messaging limits (tiers) that scale independently

Info : Reaching the upper end of the 100-number limit may require Meta review or enterprise-level approval.

Use Cases

Assign separate numbers by region, language, or department.
Run parallel WABAs under one brand umbrella.
Scale customer support or marketing without creating a new legal entity.

Why It Matters

Centralized billing: One BAN simplifies billing across all connected numbers and accounts.
Scalability: Easily expand into new regions or teams without opening separate business entities.
Flexibility: Manage multiple WABAs for different brands, regions, or service lines under one FBM.
Control: Each number maintains its own messaging tier and approval process, giving granular scaling.
