How many Coast Guard ratings and officer codes are there?
This directory lists 61 Coast Guard ratings and officer codes. Coast Guard classification codes (subspecialties, administrative codes) are browsable as separate views.

What is a Coast Guard rating?
The Coast Guard classifies enlisted members by rating, a short abbreviation like BM for Boatswain's Mate or MK for Machinery Technician. Officers carry separate specialty codes, and both are browsable here.
Where does this Coast Guard rating data come from?
Ratings follow official Coast Guard classification publications and are cross-checked against Coast Guard COOL, the Coast Guard's credentialing program.
