Holds a specific operational UIC (e.g., UIC 03368) that stays with the ship whether it is ported in Washington state, deployed in the Pacific, or undergoing maintenance.

A Navy UIC is the core of a unit's identity across all of the DoD’s systems. While a single, downloadable "Navy UIC code list" in spreadsheet form is not publicly available for security reasons, the information is systematically organized within official reference sources like the NAVCOMPT Manual, Vol. 2, Ch. 5. Its usefulness spans from the daily administration of a sailor's career to the strategic logistics that support the entire fleet. By understanding the structure of the code and knowing where to look for official sources—and how it differs from other DoD codes—you can navigate the complex administrative and logistical environment of the U.S. Navy.

🧩 – USS Nimitz is CVN-68, but her UIC is completely different. 🧩 Ghost UICs – Decommissioned units keep their UICs in a “dead” database for 10+ years. 🧩 Reserve UICs – Often start with R and change to N when mobilized. 🧩 One command, many UICs – A carrier strike group has separate UICs for the ship, air wing, and destroyer squadron.

The is a six-character alphanumeric code uniquely assigned to every command, activity, unit, or organization within the Department of the Navy (DON), including the U.S. Navy and U.S. Marine Corps. The Navy UIC Code List is the official roster of these codes, essential for personnel actions, financial transactions, logistics, and operational reporting. This report outlines the structure, significance, and methods for obtaining the current UIC list.

Most active-duty Navy UICs begin with a specific letter or number that signifies its component or branch, followed by four characters.

The subsequent characters uniquely identify the specific command, ship, or shore station. Example: Ship vs. Shore UICs

There is no single, publicly updated "master list" available for download due to operational security, but personnel can verify UICs through several official channels:

Major naval hubs utilize master UICs, with subordinate departments often using derivative codes or distinct identifiers. Naval Weapons Stations (NWS) Naval Medical Centers (NMCP/WRNMMC) 4. Special Warfare & Expeditionary
