Tail Registrations

Sat Mar 27, 2004 11:57 am

I know that the first letter designates the country, but how are the remaining numbers and letters determined? I did a search to no avail.

On most airlines that last 2 letters represents that airlines code for Instance a NW DC10-30 ship 1235 will have the registration N235NW. NW being for Northwest. however alot of NW 757s and 747s have US at the end for instance a Boeing 757-200 ship 5528 will be N528US. CO is the only airline that does not have letters have the "N"

The letters can be requested when filing your registration. You can reserve an aircraft registration of your choice for $10.

Actually, the country code can be either one or two letters or a combination of one letter and one number. I am not sure about other countries, but in the U.S. the FAA normally assigns N numbers on a random basis to private operators. There are however two exceptions.

You can request a specific N number much like getting vanity plates on your car. You can also reserve blocks of N numbers. Airlines usually do this so that they can have consecutive ship numbers on their aircraft and have them match or be close to their ship/fleet number. For example, Delta's 757's are all N6XXDA, DL or DN up to ship 699. The only exception is 690 which is registered N900PC. From ship 699 it continues as N6700 and ship number 6700, 6701, 6702, etc.

Here is a link to the FAA's registration website. There is a lookup function which can come in handy sometimes.

The letters 'I' and 'O' can not be used in US registrations (for what I hope are obvious reasons). CO's reg. Format is -Nxxyyy- where 'x' is a random number and 'y' is the aircraft's Ship number. CO did have a couple A300s at one time with reg N966C and, I think, N967C.
