Aircraft Registrations: VT-, N- and G-

If you have ever looked up at a fuselage or a tail fin and seen "VT-" painted ahead of a string of letters, that prefix is not decoration. This is the aircraft registration prefix meaning worth knowing: it is India's nationality mark, and every country that operates civil aircraft under the Chicago Convention has one of its own, N for the United States, G- for the United Kingdom, D- for Germany, and dozens more. The prefix tells you, at a glance, which country's civil aviation authority the aircraft is registered with, before you even read the rest of the tail number.

What a nationality mark actually is

Every civil aircraft in the world carries two things on its skin: a nationality mark and an individual registration mark, together called the aircraft's registration (Wikipedia, "Aircraft registration"). The system traces back to the 1944 Chicago Convention on International Civil Aviation, which set up ICAO (the International Civil Aviation Organization) and standardised nationality marks under Annex 7, similar in spirit to a car's country code on a licence plate, but tied to a specific civil aviation authority rather than to the vehicle's owner directly.

That authority is who actually keeps the register. In India, that is the DGCA (Directorate General of Civil Aviation); in the United States, the FAA; in the United Kingdom, the UK Civil Aviation Authority. The nationality mark is the visible signal of which of those registers an aircraft sits on, which matters for airworthiness oversight, maintenance rules, and which country's investigators lead if something goes wrong.

The mark itself is displayed prominently on the aircraft, commonly on the rear fuselage, with the nationality prefix and the individual mark usually separated by a dash (Wikipedia, "Aircraft registration"). It is tied to the aircraft's registration paperwork rather than to its paint job, so an airline can change its livery without touching the mark underneath.

VT- India, decoded

VT- is India's ICAO nationality mark. A typical Indian civil registration reads VT- followed by a hyphen and then a two-to-three-letter individual mark, for example VT-ABC on a narrowbody or VT-ANL on a widebody. The hyphen after the nationality prefix is the norm most countries follow: you will see it on G- (UK), D- (Germany), F- (France) and C- (Canada) marks as well. India's DGCA assigns the individual letters that follow VT- to a specific aircraft for as long as that airframe stays on the Indian register; if it is sold or leased abroad and re-registered elsewhere, it takes on that country's mark instead.

N- United States, the exception

The United States is the odd one out, and worth calling out precisely because it is the mark most readers have already seen without noticing the difference. American civil aircraft carry a plain N, with no hyphen, followed by up to five characters: a run of digits that must start with something other than zero, optionally ending in one or two letters (I and O are excluded, to avoid confusion with the numerals 1 and 0). There is no separate "individual mark" set off by a hyphen the way VT-ABC or G-ABCD are structured; the N and the number-and-letter string that follows it are read together as a single registration. If you are used to reading VT- or G- style marks, an N-number can look at first glance like it is missing a country code, when in fact N itself is the country code, just written without the punctuation everyone else uses.

G- United Kingdom, and a handful of others you will see on the apron

The UK's mark is G-, followed by four letters, for example G-EUPT. Beyond India, the US and the UK, a handful of other prefixes turn up often enough on any international apron that they are worth recognising on sight:

Prefix	Country
VT-	India
N	United States
G-	United Kingdom
C-	Canada
D-	Germany
F-	France
9V-	Singapore
A6-	United Arab Emirates

None of these are our data; they are the same public ICAO nationality-mark assignments any aviation reference carries, reproduced here as a reading aid, not a claim about any aircraft we track.

Why a tracker or a boarding pass sometimes shows a different code

The nationality mark on the tail is not the same thing as the flight number on your boarding pass, and mixing the two up is the most common confusion. A flight number ("EK 511") identifies a scheduled service operated by an airline, using the airline's own two-letter or three-letter airline code. The registration mark (VT-ANL, N12345) identifies one specific physical airframe, regardless of which route it happens to be flying that day. An airline can and does rotate several different registered aircraft through the same flight number across a week, so the tail number you see on the ground is not fixed to the schedule the way the flight number is.

How TrackMyWings helps

TrackMyWings™ is a live flight-tracking platform in development, India-first in go-to-market with worldwide coverage. A private beta shipped on 2026-08-24: Android only, on the Play internal testing track, with a small group of named testers. The wider product, including a live map and trip management for the people waiting on someone's flight, is planned for launch rather than available today, and public launch has no fixed date. Our Emirates and Air India airline pages and our Singapore Changi airport page are there to browse while the wider tracking build continues.

Questions people ask

What does VT- mean on an Indian aircraft? VT- is India's ICAO nationality mark, assigned under the 1944 Chicago Convention. It identifies the aircraft as registered with India's DGCA, ahead of the individual letters that follow the hyphen.

Why does a US registration not have a hyphen like VT- or G-? The United States mark is a plain N followed directly by up to five characters, with no separate hyphenated individual-mark segment. It is a format quirk of the US register, not a sign that the aircraft lacks a country code.

Is the registration mark the same as the flight number? No. The registration mark (VT-ANL, N12345, G-EUPT) identifies one specific airframe. The flight number (EK 511) identifies a scheduled service, and an airline can rotate different registered aircraft through the same flight number on different days.

Does the nationality mark tell you who owns the aircraft? Not directly. It tells you which country's civil aviation authority the aircraft is registered with and holds airworthiness oversight for. Ownership and lease arrangements are a separate, often more complex, question.

Does the registration mark change if an aircraft is repainted or sold to a new airline? A repaint alone does not change it; the mark is tied to the aircraft's registration paperwork, not its livery. It does change if the aircraft is sold or leased to an operator in a different country and re-registered there, which is why the same airframe can carry a different nationality mark at different points in its working life.
