There is a ‘one-click’ way to update the Contact’s address so that is matches the address of the related primary Account. On the Contact record, in the address section, select Update Address in Edit mode and Save. This copies the address of the Account to the Contact record. This feature was added as a result of user feedback!
We know it is time consuming to update Contact address but it is important to keep our data current and accurate, especially on SAP and Client accounts.
