Do aircraft registration numbers change?

[bofhlusr 453]

I'm looking into an aircraft I was involved in, a Fokker F-27-100 Friendship twin prop, which belonged to a commercial airline with registration number "PI-C507" (see below).

It appears that after a crash, a different production model or type, the Fokker F-27-200, also had the same registration number. (see the aircraft with the same registration number here:  

Fokker F-27-200 Friendship - Philippine Airlines | Aviation Photo #0134502 | Airliners.net

I'm wondering if it was the same plane that had its engine upgraded or if it was a different model. How do registration numbering work in aircraft or airliners? Can these numbers be re-used?

Not sure of your specific case, but I do know that reg numbers can and have been reused a bunch of times.

What is the difference between the two id numbers: 'Registration PI-C507" and MSN 10246 (see above)?

Which one is the actual registration number? It looks like the plane was repaired, acquired by the Philippine Air Force a year after it crashed and repainted. The so called "Registration: PI-C507 "disappeared but the MSN number remained the same ("10246"). See link below:

Apparently, it went to a museum eventually, oddly enough, as an F-27-200 (not as F-27-100):

Registration = Number plate

MSN = Manufacturers serial number

Just as rka mentioned above the canonical ID is the MSN.

Thank you both.

Kinda strange why they used the same serial number for a different model.
