Navy Enlisted Classification Codes (NEC) (2023)

While the Army and Marines use the Military Occupational Specialty Code (MOS) and the Air Force uses the Air Force Specialty Code (AFSC), the Navy uses ratings within the Navy Enlisted Classification (NEC) system to organize its jobs. It may look like there are just a few ratings, but there are many jobs classified within each rating.

Navy Enlisted Classification Codes (NEC) (1)

All recruits will go through job classification before they go to basic training. Once a recruit decides on a job (or has one selected for them based on their ASVAB), they get a classification. For example, if they will be a Navy corpsman, their rating is HM (hospital corpsman). They start recruit training as a seaman recruit (E-1). The first three Navy ranks (E-1 through E-3) are classified as apprenticeships. For example, hospitalman apprentice (HA for E-2) and hospitalman (HN for E-3). As they progress in rank, their ratings change. As a petty officer, they go from HM3 to HM1.

Once they become an HM, they specialize even more. The HM rating tells the Navy where the hospitalman is to be assigned, based on their training. If they get training as an x-ray technician, they will receive the NEC of HM-8451 (basic x-ray technician) or HM-8452 (advanced x-ray technician).

The U.S. Navy Officers’ Billets

The Navy uses a four-digit number to identify officer billets (jobs). Naval officer jobs are a bit more complicated than the NEC used for enlisted members. These codes are used by manpower personnel to indicate the categories of officers needed for each job.

The first digit identifies the officer’s community.

First DigitCommunity
2StaffMedical and JAG
3Supply Corps
4Chaplain Corps
5Civil Engineer Corps
6Limited duty

The second and third digits designate the officer’s area of specialization within the line, staff corps, limited duty or warrant officer community. The final (fourth) digit represents the officer’s current type of commission.

For example, a naval aviator will have the billet code of 1310. The first digit of 1 means the officer is an unrestricted line officer (URL), and the second and third digits of 31 indicate that they are a naval aviator. The last digit of 0 means they are a regular officer in the Navy in the grade of ensign and above.

Categories of Naval Officers

In theUnited States Navy(and USN Reserve), line officers are divided intounrestricted line officers,limited duty officers, andrestricted line officers.

Line Officers

Unrestricted Line (URL) Officers

Unrestricted line officers hold combat warfare specialties as naval aviators and naval flight officers, surface warfare officers, submarine warfare officers and naval special warfare/naval special operations (NSW/NSO) officers, warrant officers, explosive ordnance disposal (EOD) officers and Navy diving officers.

(Video) Medical Coding 101 : The NEC & NOS codes in ICD-10-CM

Restricted Line (RL) Officers

They command only within their specific specialties and are normally in fields such as intelligence, cryptology, oceanography/meteorology, engineering duty, aeronautical engineering duty, aircraft maintenance and public affairs

Staff Corps Officers

Non-line officers in the Navy are called staff corps officers. They are specialists in professional career fields, such as physicians, lawyers, civil engineers, chaplains and supply specialists

Limited Duty Officers

As officer technical managers, limited duty officers (LDOs) advance within broad technical fields related to their former enlisted ratings. They satisfy leadership and management positions at the ensign through captain level.
