First post so please be kind


Anyway hope that someone may be able to help, I have managed to get what I believe is my serial number it is - C7e3a054799195702 or it could possible be 9u47t18k931da looking around this forum it is more likely to be the first code.
If anyone could supply me with a code or advise how I go about getting it I would be very grateful.
Thanks
James
