You can find your theory test pass certificate number if you’ve lost your original letter – you’ll need it when you book your practical test, and might need it if you change or cancel your practical test.

The Driving Standards Agency (DSA) and Vehicle and Operator Services Agency (VOSA) have merged to form the Driver and Vehicle Standards Agency (DVSA).

To find your lost theory test pass certificate number you’ll need your:

• valid Great Britain or Northern Ireland driving licence number
• date of birth

You can read the Data Protection Act 1998 fair processing notice for the Driver and Vehicle Standards Agency (DVSA) before you start.
