A VIRIN (Visual Information Record Identification Number) is a unique identifier assigned by the United States Department of Defense to official still photographs, motion picture footage, video recordings, and audio recordings made by USDOD personnel as part of their regular duties. A USDOD photograph can be located via its VIRIN, even if the original WWW site from which it was obtained has since suffered from link rot.

Per Commons:File naming, there should be a meaningful name (e.g. "Apache 30 mm M230 cannon"), rather than just the ID (" photo essay 030910-A-XXXXX-7857.jpg").

The {{ID-USMil}} template can be used to mark any VIRINs in a file's description or source information. A full ingestion template {{milim}} has a number of specific fields for DoD collections.

Number structure[edit]

VIRINs are given in four separate fields separated by dashes. The fields are in this order:

Field Example Description
Field 1 060515 Date the image was shot (YYMMDD format)
Field 2 M The Service affiliation or status of the acquirer or originator (see the codes listed below)
Field 3 ZZ999 VISION ID
Field 4 001 Sequence number for that day (sequence numbers restart at 001 each day, not each shoot)

Field 2, the service affiliation or status is abbreviated as follows:
