I bought a new Mitsubishi car about 3 months ago and the red number plate ended 1047 . I had to go to the UK and when I got back to my house in Thailand the car now had a normal white plate but the number had changed to a completely different number . I asked my lady if she had chosen another number and she said that she had not and this was the number given by the transport department . Is this number change normal ? 

Yup, your red plate was just a temporary "dealer" plate.

 

Your car is now properly registered.

The red plate is the car dealers plate, a dealers plate.

It will go on the next new car he sells now you are finished with it. 

 

Your white plate had to be ordered, you can request a specific number, if not you get what you are given.
