Yes. Google the tail number including the prefix (N) for US registrations and there will be an FAA supplied page that will give you the owner and other pertinent information. If you don't know just by looking at it and remembering who owns what plane, you can look it up in the FAA aircraft registration database.

You can search for owner, make, and model information for an aircraft on our Aircraft Registration Inquiry website.

The U.S. received the "N" as its nationality designator under the International Air Navigation Convention, held in 1919. The Convention prescribed an aircraft-marking scheme of a single letter indicating nationality followed by a hyphen and four identity letters (for example, G-REMS).

These numbers are located on the aircraft tail, so they are sometimes referred to unofficially as "tail numbers". On the Northrop Grumman B-2 Spirit bomber, lacking a tail, the number appears on the nose gear door.
