Could anyone help me make a class, use-case, sequence, and activity diagram for the following modules?

An e-commerce company has a website that needs to confirm that a user's profile name and address is a real address before delivering the products. Create a system that could handle this request.

Here is what I currently have for the class diagram:

Delivery -OrderlD (int) has DeliverylD (int) OrderlD (int) DeliveryDate (string) Address (string) TotalCharge (double) Customer -GetOrderlD) GetTotalCharge(0) -CustomerName (string) -CustomerlD (int) -Address (string) GetDeliveryReport() -GetCustomerlDO +ValidateAddress():bool
