Phone number considerations for use with a WhatsApp Business Account
When you link a phone number with your WhatsApp Business Account (WABA), you should consider the following:
-
Phone numbers can only be linked to one WABA at a time.
-
The phone number can still be used for SMS, MMS, and voice calls.
-
Each phone number has a quality rating from Meta.
You can obtain an SMS-capable phone number through AWS End User Messaging SMS by doing the following:
Make sure that the country or region for the phone number supports two-way SMS.
Request the phone number. Depending on the country or region, you may be required to register the phone number.
Enable two-way SMS messaging for the phone number. Once setup is complete, your incoming SMS messages are sent to an event destination.
