P.O. Box Consolidation Crosswalk

In our efforts to provide better service to our providers, National Government Services has consolidated many of their Post Office Boxes. The following crosswalk represents the changes that have occurred through December 21, 2007. This crosswalk represents an all-inclusive list of new addresses for National Government Services. Please note that this crosswalk does not represent a comprehensive list of all National Government Services mailing addresses; it only includes those that have changed due to this consolidation project.
