If you want to apply for an Official Business Account you will need:
2-factor verification enabled on the WhatsApp Client (For Logisy hosted clients, we take care of this step)
Valid Facebook Business ID with verified business
Brand that doesn't violate WhatsApp's policies, especially its Commerce Policy
Reach Quality Tier 2. You can find more info here Capacity, Quality Rating, and Messaging Limits - WhatsApp Business API (facebook.com)
There might be other internal criteria or standards which is not publicly shared by WhatsApp.
We also recommend the following to increase the chance of getting promoted:
It's always good if there is some ad spend on Facebook.
You should have a large following on Facebook (and Instagram) which indicates brand awareness. Example: 20K+ likes/followers on your Facebook or Instagram pages.
You can find more information on the Official Facebook Documentation.
Logisy does not guarantee that any account will be promoted to an Official Business Account. The review process is conducted by the WhatsApp API Support Team and can take up to 7 days.
If your application is successful, the account will be upgraded automatically so there will be no further action required.
If your account is rejected, you may apply again in 3 months (this timeout is set by WhatsApp). WhatsApp do not give reasons for rejection so please do not ask Logisy for this information. You can assume your account did not meet the criteria. You can attempt to improve your chances by adhering to the recommendations above and try again in the future.
