Although the customer number has been registered with WhatsApp, the account type and current status are still unknown. If commercial accounts, ordinary accounts and banned accounts are mixed in the same list, it will affect customer classification, marketing reach and sales follow-up efficiency.
It is impossible to determine whether the number corresponds to a normal account or a WhatsApp business account
Banned accounts were mixed into customer lists, resulting in a large number of invalid contacts.
Account status may change, and historical data cannot reflect the current situation.
Manually checking the account type and status one by one makes it difficult to handle large batches of numbers.
The detection results lack time records, making it impossible to judge how new or old the data is.
