Registry

The USS Enterprise-D's registry number on the underside of its primary hull.

A registry is a place to record or register information. One such registry is the Vulcan Genome Registry.

Vessels were often registered by agency. They may record a vessel's name, registry number, history, and basic ship information. Ship registries were used as early as the 19th century.

In the 23rd and 24th century, Star Fleet vessels were able to check both historical registries from Earth and Vulcan as well as the Star Fleet Registry.

Registry numbers and prefixes

In some governments and agencies, a ship entered into a registry received a prefix that was placed before the vessel's name.

This prefix was used to easily identify the vessel as belonging to that agency. A registry prefix should not be confused with a ship's prefix code.

Items listed in a registry generally had a number or code to help identify the specific entry. Registry numbers can be changed, as was the case of the USS Yamato.

In some registries, the registry number was preceded by an abbreviation as well:

Aside from the registry prefixes, Star Fleet also uses letters after the main registry prefix to further define specific types of craft. Star Fleet would also use sequential lettering after a registry number was repeated to honor a former vessel.
