What is the importance of the NCC

Registration number

A Registration number identifies ships, spaceships or other vehicles according to their affiliation or the time of their keel-laying, their start of construction (possibly also the decision on this) or their commissioning. It is used, for example, by the Federation's Starfleet, but there are also registration numbers on spaceships outside of Starfleet.

Structure of registration codes [edit | Edit source]

A registration code usually consists of three parts:

  • A prefix, which usually consists of a two- to three-digit letter code
  • A two- to six-digit number
  • If necessary, a suffix, which is either a single letter or a single digit, separated from the number with a hyphen.

Prefixes [edit | Edit source]

Pre-Federation [edit | Edit source]

At the time of the Federation [edit | Edit source]

Starfleet [edit | Edit source]
Federation civilian starships Edit source]
Spaceships of individual races Edit source]

Suffixes [edit | Edit source]

Some spaceships, such as the Enterprise, have a series name (NCC-1701- (A, B, C, D etc.))

Known registration numbers [edit | Edit source]

Federation and Earth Starfleets [edit | Edit source]

Others [edit | Edit source]

Borg [edit | Edit source]

The Borg have no ship names, but rather their own unique combination of numbers for each ship.

Prefixes for names [edit | Edit source]

Federation / Earth Edit source]

In the following, only the prefixes for ship names used in the Federation or on Earth are listed:

Federation Starfleet mostly uses the prefix "USS".

Numbering [edit | Edit source]

Starfleet spaceships have two to six-digit numbers as their actual registration number. These numbers range from in the 22nd century (ENT:Departure into the unknown, part I.) until the 29th century (VOY:Time ship "Relativity"). The orders of magnitude of the numbers seem to be assigned in chronological order. For example, there are hardly any known spaceships with a four-digit code from the 22nd century and only a few spaceships with a five-digit code from the 23rd century, while most spaceships in the 24th century have a five-digit code.

However, the following examples speak against a strict chronological arrangement of the numbers:

  • The USS Bonaventure, als has the registration number NCC-10283 (or). However, with this registration code, the order of prefix and number differs from the later usual order. It is therefore possible that this is a different registration system. (TAS:The time trap)
  • In 2285 the highest known registration number is NCC-3801. It is likely that this is not automatically the highest registration number at this time. (Star Trek II: The Wrath of Khan) In the same year a little later the USS Excelsior put into service with the registration number, which is clearly much lower. Also some serial spaceships of the Excelsior-Class, like the USS Repulse with the registration number are below.

Apparently there is also a correlation between the registration number and the spaceship class, since the numbers of spaceships of the same class are often very close together.


  • Ambassador-Class: (NX-10521, NCC-10532), NCC-26136, NCC-26510, NCC-26517, NCC-26531, NCC-26632, NCC-26849
  • Galaxy-Class: NCC-70637, NCC-71099, NCC-71807, NCC-71832, NCC-71854, NCC-71867

It can be assumed here that Michael Okuda & Co deliberately provided spaceships of the same class with similar numbers. It is not known whether there is a deeper meaning behind it or whether it is just a simple way of making work easier.
