Yes
In addition to registration numbers, display of a valid state registration decal is required while boating.
Military aircaft display national markings in order to be identified by other aircraft as enemy or friendly. Modern US Air Force jets use markings that lack color and are shades of the camoflage. Civilian aircraft are only required to carry a Registration identification number. This registration ID includes Letters and Numbers and each country has a unique prefix Letter(s). For example, all aircraft registered within USA begin with "N" and this registration is commonly referred to as the "N-number". However, I do not think a civilian aircraft is required to display the national flag.
A boat's registration numbers appear on the stern of the boat. I am not really sure of the answer. I wanted to point out the fact that you forgot the apostrophe in your question. It should read: "Where do you need to display your boat's registration numbers. Thank you, and enjoy your day!!
They don't. Each country uses a different letter for their aircraft registration. All aircraft owned and registered in the US uses the "N" prefix.Canada aircraft are registered with a "G".
Every military or civilian aircraft in the world has civil or military recognition or registration numbers. All civil aircraft numbers are led by a country code, for instance 'C ' for Canada, 'G' for UK, 'N' for USA and so on.
No one assigns the N-number. You get to request one. You can request one on the FAA website.

Since 1948 all American aircraft have been designated a 'N' number. Those few remaining aircraft with 'NC' were registered before 1948, When 'NC' meant North American Civil.
Vehicle registration numbers are a means of determining the owner of a vehicle. Usually, when purchasing a vehicle from a dealer, the dealer will transfer the registration number to the purchaser and fill out the required forms.
Firearms don't have registration numbers, they have serial numbers. No way to know who was the first to put a number on a firearm. Military firearms have had serial numbers for many years, to aid in the accounting for large numbers of identical guns. Serial numbers were not required by law in the US until the 1934 National Firearms Act reqired them on machine guns and handguns. The 1968 Gun Control Act required them on newly made rifles and shotguns.

Look closely at the Airplane in his Gold commercial on TV. They have gone to considerable trouble to "Blank Out" the Aircraft Registration Numbers on the fuselage ! Hmmm . . . . ;-)
