What can be used to confirm a DOD ID number if the Soldier does not have a government ID card?

Using an official Unit Alpha Roster to confirm a DOD ID number is appropriate as this roster is an official document that lists all service members in a unit along with their respective identification numbers and other identifying information. It is regularly updated and maintained by unit personnel to reflect the current status of all assigned members, thereby making it a reliable source for verifying a Soldier's DOD ID number, especially when they do not possess their government-issued ID card.

The other options, while potentially containing information about Soldiers, may not directly provide the DOD ID number in a standardized manner. For example, a Unit Commander's Letter or Deployment Orders may reference the Soldier and their role but typically do not include the DOD ID number specifically. Meanwhile, a Military Pay Stub does show personal information related to pay but may not consistently contain the DOD ID number, as it is primarily focused on financial details. Therefore, the Unit Alpha Roster remains the best choice for confirmation of DOD ID numbers.
