So a client of ours recently ordered a temporary number for whatsapp. when he registered, there were existing chats on there. So the client asked why there was existing text or chats on their whatsapp account.
Phone numbers can be reissued and it's really out of our hands. For example: If someone bought a SIM-card, registered whatsapp using that number then stopped using the number. After 3 months of sim-card deactivation, the cellphone company can reissue the number. I can assure you that our system will only allow a number to be used once per service.
