From 8 June 2015, the photocard licence counterpart will not be valid and will no longer be issued by DVLA.

What this means for you

Photocard driving licence holders
When DVLA stops issuing the counterpart, you should destroy yours but you still need to keep your current photocard driving licence.


Entitlements and the status of your driving licence won’t change.

Paper driving licence holders (those issued before 1998)
These will remain valid, and should not be destroyed.
