Backend Source of Address Search Feature in US Oracle Payroll Tax Engine (OPTE)

Hello,
We are currently working on testing of US Oracle Payroll Tax Engine in our dev11 environment. And we wanted to know where in the backed is the Address Search feature referencing these addresses from? According to the US OPTE Transition plan we need to Load Geographies process to import Oracle’s expanded master geography data set (ORA_HCM) to support address LOVs. Is there a certain table/view we can access this master geography data set from or are these going to be managed by Oracle? As moving forward we need to inform the same to our taleo team of the accepted list
