It is a regulatory requirement to have the registration under the wing here in Australia, and I believe pretty much everywhere. Here, it is covered by Civil Aviation Safety Regulation Part 45:
Quote: 45.045 Number and location of sets of markings — fixed-wing aircraft
(1) On a fixed-wing aircraft, 3 sets of the aircraft’s markings must be displayed, as follows:
(a) 1 set either on the under surface of the port wing or across the under surface of both wings, in each case as set out in subregulation (2);
(b) the 2 other sets on:
(i) the fuselage, as set out in subregulation (3); or
(ii) engine nacelles or similar fixed obstructions on the fuselage, as set out in subregulation (5); or
(iii) the vertical tail, as set out in subregulation (6).
(2) A marking on the wing of an aircraft:
(a) must have its top towards the leading edge of the wing; and
(b) must be as nearly as possible parallel to the leading edge, and half-way between the leading and the trailing edge, of the wing.
(3) If the markings are on the aircraft’s fuselage, there must be 1 set on each side of the fuselage:
(a) between the trailing edge of the wing and the leading edge of the tailplane; or
(b) if the aircraft is of canard configuration and has no tailplane — between the trailing edge of the foreplane and the leading edge of the wing.
(4) In subregulation (3):
tailplane includes the tail surfaces of an aeroplane that has a vee-tail.
(5) If there is an engine nacelle or similar fixed obstruction on the part of the fuselage mentioned in paragraph (3) (a) or (b), there may be a set of markings on each nacelle or obstruction.
(6) If the markings are on the aircraft’s vertical tail, there must be :
(a) if the aircraft has a single vertical tail — 1 set on each side of the tail; or
(b) if the aircraft has a multi-vertical tail — 1 set on the outer side of each of its outermost surfaces.
