The DoD ID/EDIPI number stays with the owner throughout his or her career with the DoD or USCG, even when he or she changes armed services or other departments within the DoD or the USCG. For retired U.S. military personnel who subsequently become DoD or USCG civilians or DoD or USCG contractors, the DoD ID/EDIPI Number on their CAC will be the same as on their DD Form 2 Retired ID Card. For non-military spouses, unremarried former spouses, and widows/widowers of active, Reserve or Retired U.S. military personnel who themselves become DoD or USCG civilians or DoD or USCG contractors, the DoD ID/EDIPI Number on their CAC will be the same as on their DD 1173 Uniformed Services Privilege and Identification Card (e.g., Dependent ID card).
