Lost code for ford transit 4000 rds. Model (serial) number:- M366549 ?

I recently had to charge the battery on ford transit and after I had done so the radio won't work because it needs the code. As the vehicle was bought second hand from a hire/rental company I never got the code for it. So now I have no way of listening to the radio when driving.
I have the Model (serial) number:- M366549.

Is it possible to have the code to unlock the radio with the serial number ?
