NEW: Mailing Addresses Effective December 5, 2011

Effective December 5, 2011, CGS consolidated our mailroom locations to coincide with the final transition of our J15 segments. Please use the NEW mailing post office boxes listed below. The Chattanooga, TN addresses are no longer valid and in the future, mail sent to those locations may be returned to the sender. Also, please closely check that you are using the correct address for each inquiry type. When mail is sent to the wrong address for the inquiry type, it results in a delay in processing that inquiry/claim.
