Address book maintains customer addresses, which are used for billing and shipping products. Customers may add as many addresses as needed via their account section.
How it works?
Registered customers can access their address book in My Account section of the store where they could add, modify or delete their addresses as required in this section.
Store admin can access those customer addresses at Customers section in the administration. This section enables the store admin to add, modify or delete existing customer addresses as necessary.
