FAA regs on aircraft registration

A fascinating read. Hmm, is 'fascinating' the word I'm looking for?

I hadn't realised before that the N number need only be displayed on the
fuselage sides (or vertical tail). In the UK (last time I had reason to check
- which doesn't happen very often), the registration also has to appear on
the lower wing surfaces in letters at least 50cm high. That's about 20
inches for unreconstructed anglophones.

It used to be that way in the US a few decades back. I wish it still
were - sometimes getting registrations off of airplane photographs
when the plane is in the air is a bit difficult. No problem with most
non-US airlines I see going into SEA that carry theirs under the
wings.
