Transponder codes change all the time. You get a new one from ATC when you get your clearance. I've even had different transponder codes on a single flight.

Registration numbers (N numbers) can be changed, but it does require paperwork filed with the FAA.

The key is the serial number. This should not change for the life of the aircraft. The airworthiness certificate is tied to the serial number.
