It should be assigned by the regulator when you register the aircraft

Wherever you registered your aircraft can tell you this. I just recently did it for my transponder, but I assume I'm not in the same country as you.

They sent me a doc with the following info:

Reg.-Mark   Decimal    Binary    Octal    Hexadecimal

( I would put my values in here but I'm afraid someone will use them, and then cause an international incident. )
