Does your driving license number change if you request a new card?

[AmDaMan]

Right the situation is this;

I lost my driving license a bit a go and so I ordered a replacement..
I then lost the replacement and found my old car (don't ask me how)

Now I've just booked my online motorcycle theory and put in my old drivers licence number.. will this be invalid? That's probably a daft question but I had the opportunity for a cancellation and I haven't got around to ordering another card yet!

PS I still have both counterparts.

Thanks.

Thanks for the replies.

As long as the driving license number stays the same I should be ok then
