A letter I have here from the BATF clarifying whether it was necessary to put a serial number or marking on my projects says:

"Additionally, although markings are not required on firearms manufactured for personal use (excluding NFA firearms), owners are recommended to conspicuously place or engrave a serial number and/ or other marks of identification to aid in investigation or recovery by State or local law enforcement officials in the event of a theft or loss of the privately owned firearm."

Firearms manufactured for sale are regulated a bit differently than ones made for personal use.
