Everything worth knowing, nothing that isn't.
What it signals
A green tick tells customers the account genuinely belongs to the brand, not an impersonator — which lifts open and response rates and protects against fraud. It sits above the display-name verification most accounts have. See /answers/what-is-whatsapp-business-api.
How it's granted
Meta reviews the business's notability and compliance; the badge cannot be purchased and is not guaranteed. You submit the request through your BSP, which manages the WhatsApp Business Account. See /answers/what-is-whatsapp-bsp.
Verification vs the green tick
Most business accounts complete display-name verification, which is required to message at scale; the green tick is an additional, selective mark of notability on top of that. See /answers/whatsapp-for-customer-support.
