How verification works
The WhatsApp green checkmark (Official Business Account) is assigned by Meta to notable companies. It's not automatic or purchasable: Meta assigns it proactively to companies with strong online presence, recognized brands, and good-standing Meta Business accounts.
Optimizing your profile without the green checkmark
Even without the green checkmark, you can optimize the Business profile for maximum professionalism: high-resolution logo, clear business description, correct availability hours, address and website.
Impact of verification on message rates
Verified numbers with green checkmark have lower block rates than unverified numbers at equal message quality.
