Lost your theory test pass number? Get it back free

Last reviewed against gov.uk on

Your theory test pass is recorded as a pass certificate number, printed on the letter the test centre gives you on the day. If you can’t find the number, the official gov.uk service at gov.uk/find-theory-test-pass-number retrieves it free of charge and emails it to you. You only need your UK driving licence number and your theory test booking reference.

Your theory test pass certificate number will be sent to the email address you used to book your theory test.

Where the pass number normally lives

When you pass the theory test the test centre gives you a letter with your pass certificate number and your result on it — that letter is the copy gov.uk points you back to. The email DVSA sent you when you booked is a different document: it carries your booking reference number, not your pass certificate number. That inbox is still worth searching, because the booking reference is what the gov.uk lookup asks for — and the lookup is what sends your pass certificate number, in a separate email, later.

Check, in order:

  • The printed letter the test centre handed you when you finished — the number is printed near the top.
  • Your email inbox on the address used to book the test, for the booking confirmation carrying your booking reference number (search for “DVSA” or “theory test booking confirmation”).
  • Your spam / junk folder if it isn’t in the inbox.

How to look it up at gov.uk if you can’t find it

The official lookup is at gov.uk/find-theory-test-pass-number. The request runs in your browser, the service is free, and the pass certificate number is then emailed to the address you used when you booked the theory test. Anything that charges you for this is not the official service.

You need two pieces of information to use it:

  1. Your UK driving licence number. This is the long alphanumeric code on your photocard provisional or full driving licence.
  2. Your theory test booking reference number. DVSA emails this to you at the time you book the theory test (subject usually “Theory test booking confirmation”).

Enter both and submit. There’s no postal step. If you don’t have the booking reference, the same gov.uk service lets you ask for your booking details — see below for the contact route if neither email is available.

If you don’t have your booking reference either

If the booking confirmation email is gone you do not have to phone: the same gov.uk service lets you ask for your booking details. Contact DVSA directly only if that route doesn’t work for you, or if you need a replacement letter to take to a non-car driving test:

  • Phone: 0300 200 1122 (Monday to Friday, 8am to 5pm). This is the DVSA theory test customer services line — the same number used for booking.
  • Email: theorycustomerservices@dvsa.gov.uk.

Have your UK driving licence number ready when you call — DVSA uses it to look up your record. They may also ask security questions to confirm your identity before releasing the number.

The number itself does not expire — but the 2-year clock does

Your pass certificate number stays the same forever. What expires is the 2-year validity window: you must pass your practical driving test within 2 years of the date you passed the theory test, otherwise the certificate lapses and you have to take the theory test again. Retrieving the number doesn’t reset that clock, and the gov.uk lookup service still returns the number after the 2 years are up — but at that point it’s information only, because DVSA’s booking system will refuse to book a practical test for a lapsed certificate.

For the full rules on the 2-year window — including the calculator, the fact that failing the practical doesn’t reset it, and what to do if time is running out — see our dedicated theory certificate expiry guide.

When you actually need the pass number

You may be asked for the pass certificate number when you:

  • Book your practical driving test at gov.uk/book-driving-test. You usually do not need it to book — the booking service asks for your UK driving licence number and a payment card — but DVSA can ask for it, so it’s worth having to hand.
  • Change or cancel a practical test booking — same system, same number.
  • Apply for a category upgrade (e.g. from car to motorcycle) where a theory pass is a prerequisite.

You do not need the number to apply for a full driving licence after you pass the practical — DVSA’s systems link the records automatically.

Beware of paid “lookup” services

Several third-party sites offer a “theory test certificate lookup” or “pass number retrieval” service for a fee — typically £15-£25. The official gov.uk service does the same job free, and there is no information a third party can access that gov.uk doesn’t. If a site is asking for your card details to retrieve your DVSA pass number, close the tab and use the official link above. For the wider pattern of third-party booking and lookup middlemen and how to spot them, see our booking scams guide.

Quick reference

  • Look up the number: gov.uk/find-theory-test-pass-number — free; DVSA emails the number to the address you used to book the theory test.
  • You need: UK driving licence number + theory test booking reference.
  • If you don’t have the booking reference: ask for your booking details in the same gov.uk service; if that doesn’t work, 0300 200 1122 (Mon–Fri 8am–5pm) or theorycustomerservices@dvsa.gov.uk.
  • The number itself doesn’t expire — but the 2-year validity window does (see expiry guide).
  • Don’t pay third parties — the official lookup is free.

Lost certificate — FAQs

How do I book the UK theory test?

Book only through the official GOV.UK service at gov.uk/book-theory-test — that is the only valid booking route for DVSA tests. You need your UK driving licence number (provisional is fine), an email address and a credit or debit card. Third-party sites that charge to book are unofficial.

How long is a theory test pass valid for?

Two years. You must pass your practical driving test within two years of your theory test pass — otherwise you will need to retake the theory test.

Is the theory test fee the same for cars, motorcycles, lorries and buses?

The car and motorcycle theory test is £23. The lorry and bus (LGV/PCV) test is structured differently — £26 for the multiple-choice part plus £11 for the hazard perception part, taken as separate bookings.

Does the 2-year clock start on the day I pass or the day after?

The day you pass. The certificate is dated the day of your theory test, and the 2-year window runs to the same calendar day two years later, inclusive — DVSA's booking service accepts a practical on the anniversary date. For example, a certificate dated 21 May 2026 is valid for a practical test taken on or before 21 May 2028; from 22 May 2028 onward you must retake the theory test.
