Nose vs. Tail Number

Does anyone know the difference between the Tail and Nose numbers of UA planes? I thought I knew my airplane stuff (being a private pilot and all), and of course I am familiar with Tail Numbers, but not Nose Numbers. I searched these forums and didn't see any threads on it.

Last week I'm on a OAK-IAD flight last week on Tail N819UA. The manifest (conveniently viewable in F-class) also says Nose: 4019 (together like Nose/Tail 4019/N819UA).

On this census site of planes, 4019 is shown as the F/N number for the United plane with this Tail #. Is this a UA designator for this aircraft ?

I believe the number on the nose gear is the company's 'ship' number.. a number which UA designates to its aircraft.
The number on it's tail is of course it's N----- registration number.

There are three numbers visible on the exterior of the airplane. The registration number such as N180UA and both a nose number and then the same number painted low on the rear fuselage. The nose number for N180UA is 8180. That is the number they airline uses to designate the fleet type, the 8, and the interior configuration or some other particular identifier such as a 737-300 vs a 737-500.

You will begin to see the international fleet nose numbers change as the new interiors get installed. That way if there is an aircraft swap needed or routing needs to schedule a route they know instantly which type of plane they are working with.

Hope that helps.

Ok, who's going to take responsibility for tracking this once the new interiors start rolling out?

Whoever reports the first one gets a free CR-1 from me.

Here is some info I have from a UA aircraft scheduling spreadsheet. Let me know if you are interested, and I can send it.

It gets kinda confusing when dealing with the 737:

Boeing 737-300 10XX 8/112
98XX 8/120
99XX 8/112
Boeing 737-500 15XX 8/102
16XX 8/96

All of the registration numbers (like a license plate) will start with 3. So all of these 737s will have a reg number like: N3XXUA

The N indicates that the aircraft is registered in the US. You will notice Canadian planes begin with C-XXXX and so forth.


Airbus: regnumbers will be N4XXUA for the 320 series and N8XXUA for the 319 series:

Airbus 319 40XX 8/112
Airbus 320 45XX 156 overwater TED
46XX 12/126 overwater ops, latin market
47XX 12/126
Airbus 320 48XX 156 TED aircraft
49XX 156 TED aircraft



On to the 757s: regnumbers will be N5XXUA

Boeing 757-200 54XX 24/158
55XX 24/158 ETOPs
56XX 24/158 overwater ops
57XX 12/26/72 Premium Service

767 is pretty easy: regnumbers will be N6XXUA

Boeing 767-300 63XX 10/32/151 ETOPs
67XX 34/210 ETOPs - Hawaii/Domestic



777 will be N2XXUA or N7XXUA

Boeing 777-200 23XX 12/49/197
25XX 36/312 Hawaii/Domestic markets
26XX 10/45/198 Pacific 777
29XX 12/49/197 Range 777


And finally, the 747: N1XXUA

Boeing 747-400 81XX 14/73/260

Ah, this has been one of my obsessions over the past several years while flying United. I've been keeping track of the aircraft I've flown by their "N" registration numbers, as well as the nose number as referred to by UA.

Incidently, the 2nd digit on the nose number is actually the differentiator for interrior configurations. For example, there have been several different nose numbers for the 744, 84xx, 80xx, and 81xx. As far as I can tell, they have all been standardized to 81xx now.

Here's a run down of the type and associated nose numbers (some may be obsolete):

733 - 99xx, 98xx, 13xx
735 - 16xx, 15xx
744 - 81xx
752 - 54xx, 56xx, 57xx (PS)
763 - 67xx
772 - 26xx, 29xx
319 - 40xx
320 - 46xx, 47xx, 49xx (Ted)

Last I checked the -500's had reg numbers N9XXUA.

Great info on which interior (or operational, in the case of the 757) config each second digit corresponds to, that's good to know. Thanks for posting!

Yes, this is great info. Don't forget that two of the 737-322's have N numbers in the 200 series: N202UA and N203UA.
