Check if the WhatsApp number can still be registered - Digital Planet Screener
Many people often encounter this problem when doing WhatsApp marketing or batch registration: they have entered their mobile phone number, but they cannot receive the verification code, or their account is blocked as soon as they register. Most of these situations are not platform system failures, but that the number you are using has been registered, banned, or marked as a high-risk number by WhatsApp. Therefore, before registering, the most important step is to check whether this number can still be used to register for WhatsApp. If you ignore this step, you will waste not only a registration opportunity, but also the value of the promotion budget, account resources and even the entire batch of data.
