**Do we need a Facebook business manager account to use whatsapp business? If yes, then why is it mandatory?**

\
Whatsapp is a part of Facebook and as a part of the Facebook family of business they want to know the authenticity of the account..Once WABA is mapped with Fb business manager Id it means that you are a legitimate business and are verified. 

**Can I use a phone number that is already on WhatsApp?**

If that phone number has not been used on WhatsApp Business API, you can use that phone number. Follow the migration steps outlined here to reuse that phone number.

**Can I run multiple WhatsApp Business API Clients with the same phone number?**

No. At any given time, you can only have one setup of the WhatsApp Business API running for a single phone number. As soon as you register a second setup, your first setup will get kicked off and fail.

**Can we use toll free numbers as my whatsapp number?**

Toll-free numbers are allowed as long as your country code is included. The reason is that toll-free numbers without country codes cannot be uniquely identified — the same number can apply for two different countries.

Also note that there are added complexities around toll-free numbers. Typically, if you call a toll-free number with the country code when you're inside the country, it will fail. This means that there is a chance your customers from your country will try to dial what shows in the business contact (country code included) and they won't be able to reach you. If this is a concern, you will need to let them know explicitly.

**How many messages can I send on the first day once my Whatsapp acount is activated? Is there any limit?**

Once your account is activated and live there is a messge limit per day of 1000, once this limit is breached the next limit is set up to 10k messages and then 100k and so on.
