Hoe kun je WhatsApp Business-app laten verifiëren ?
Dus zoon groen vinkje ?

Die kan je nog niet krijgen:

"Verified business account

WhatsApp is exploring ways for you to connect with the businesses that matter to you.
WhatsApp has verified that the phone number of this contact belongs to the associated business. The green badge next to the contact's name confirms that this is a verified business account.
If you'd like to stop a business from contacting you, you can block them.


Note: WhatsApp business verification is currently limited to a small number of businesses participating in a pilot program."
