When setting up your WhatsApp account in Chatarmin, it’s important to use a phone number that meets the following requirements:
✅ Requirements
1. The number must be completely free and unused with WhatsApp
The phone number must never have been connected to:
WhatsApp Messenger
WhatsApp Business App
WhatsApp Channel
❗ If the number has been used with another WhatsApp API provider, it may still be used - but only if it is reachable via call or SMS to receive the Meta verification code.
2. The number must be able to receive calls or SMS
For the Meta verification, the number must be able to receive calls and SMS, as you will receive a verification code this way.
3. Landline (Festnetz) numbers can be used
If you want to use a landline number (e.g., the one listed in your legal imprint/Impressum), that’s possible too - as long as it can receive the verification code from Meta.
