Lost your Licence?
If you have lost either part of your licence you will need to get a replacement licence as it is now impossible to conduct a test without the examiner seeing both parts.
You will need to either fill in a form D1 from the post office or phone DVLA on 0300 790 6801 Monday to Friday 8am to 7pm, Saturday 8am to 2pm.
Alternatively you can do it online by following this link:-

It costs £20 to get a replacement so it really does make sense to put both parts somewhere very safe!
