To help prevent inadvertent disclosure of controlled information, all contractors are identified by the inclusion of the abbreviation "ctr" and all foreign nationals are identified by the inclusion of their two character country code in: - DoD user e-mail addresses (e.g., email@example.com firstname.lastname@example.org); - DoD user e-mail display names (e.g., John Smith, Contractor <email@example.com> or John Smith, United Kingdom <firstname.lastname@example.org>); and - automated signature blocks (e.g., John Smith, Contractor, J-6K, Joint Staff or John Doe, Australia, LNO, Combatant Command). Contractors who are also foreign nationals are identified as both (e.g.,email@example.com). Country codes and guidance regarding their use are in FIPS 10-4.
