Marine Corps Personnel Locator                                                                              The U.Ss Marine Corps can find and provide the duty stations for active duty USMC personnel and USMC reservists. For retired Marine Corps personnel, the locator service can provide the city and state for the person, but they will not provide the person's address.                                                                                                  Locating Former Marines  The Separations and Retirement Branch (MMSR-6) assists individuals wishing to locate former or retired Marines. To request assistance with locating a former or retired Marine there is a 3 step process.                                                                             Step #1, Write a letter to the person you wish to contact. Seal the letter in a return labeled and stamped envelope. Write the name of the Marine  on the letter but leave the address portion blank.                                                                                               Step #2. Write another letter in which you state that you would like to have the enclosed letter forwarded to the Marine that you are trying to locate. Include as much information about the person as possible, i.e. full name, last know rank, year of retirement or separation, and units they may have served with.                                                         Step #3, Package the letter, and your return addressed, stamped letter, in another envelope. Address the envelope to:                                                             Headquarters U.S. Marine Corps Manpower and Reserve Affairs (MMSR-6 ) 3280 Russell Road Quantico, VA 22134-5103                                                                                  Please do not send correspondence via certified or registered mail because it will delay processing.                                                                                  The Separations and Retirement Branch will use DFAS records and other military data bases to attempt to locate an address to forward your letter.                                                             Once the letter is forwarded, it will be up to the individual you are looking for to decide if they wish to respond. There is no guarantee that the Separations and Retirement Branch will be able to honor your request or that the address available will be correct. It is important that you provide adequate information about the individual you are looking for, to ensure that in cases of Marines with common names, the letter is forwarded to the right person.                                                                     For more information, contact MMSR-6 at 703.784.9310/1/2 or 800.336.4649 Option #0.                                                      The Marine Corps locator service will also provide the service person's current rank and unit address; however, the USMC locator office will not forward mail except in special cases.                         Telephone requests to the Marine Locator can be made at 703.640.3942/43 - telephone requests are free for immediate family members and government officials calling with official business. In addition, telephone service will be provided at no cost to any person, organization or business, if the Marine personnel locator decides the information would benefit the service member.
