### 2.1 Add phone number

1. Click on “Add phone number” button in “[Step 5: Add a phone number section](https://developers.facebook.com/apps/759218118860831/whatsapp-business/wa-dev-console/?business_id=1501389280339074)”. Fill out your profile name and add the number:\
   a) Add profile display name prescribed by Meta. Make sure it’s associated with your business’s actual name. If it is not associated, Meta is likely to reject it. For Research bots, we typically advise \[business\_name] + Research as your Display Name. See [Display Name Guidelines](https://www.facebook.com/business/help/757569725593362) article for more details.\
   b) Choose a category and business Description\
   c) Add number: Select country code and add a number to receive OTP via SMS or phone call to verify
