Your driving test reference number is a unique code your state's DMV or licensing authority assigns when you book a behind-the-wheel test

This number identifies your specific test appointment in the system. You'll need it to reschedule, cancel, check your test status, or show up on test day. The format and what it's called varies by state — some call it a confirmation number, appointment number, or test ID — but the purpose is the same: it's how the testing office knows which appointment is yours.

You receive this number when you complete your booking, usually by email or on-screen when ready after payment. Write it down or save the confirmation email. If you lose it, you can contact your state's DMV to retrieve it using your name, date of birth, and driver's license number or learner's permit number.

Key Takeaways

  • Your reference number is issued by your state's DMV when you book your behind-the-wheel test and appears in your confirmation email or on-screen receipt.
  • You must bring this number or your confirmation document to your test appointment, or the testing office may not recognize your reservation.
  • Use your reference number to reschedule, cancel, or check the status of your test before your appointment date.
  • If you don't have your reference number, contact your state's DMV with your personal information and they can look up your appointment.
  • The name and format of this number differs by state — it may be called a confirmation number, appointment ID, or test number.

Where to find your reference number

Your reference number appears in the confirmation you receive when ready after booking. If you booked online through your state's DMV website, check your email for a confirmation message — the number is usually near the top or bottom. If you booked by phone or in person, you should have received a printed receipt or confirmation slip with the number on it.

Some states also let you log into your DMV account online and view your upcoming appointments and their reference numbers. Check your state's DMV website to see if this option is available. The login usually requires your driver's license number or learner's permit number and a password you created during registration.

What to bring on test day

Bring your reference number or the full confirmation document to your test appointment. Many testing offices ask you to provide it when you check in, so they can pull up your appointment details and verify that you're the person scheduled. Some offices scan or photograph the confirmation, while others just write down the number.

Even if the testing office doesn't ask for it, having it with you prevents delays. If there's any confusion about your appointment time or details, your reference number settles it when ready. Keep it in the same place as your learner's permit and the documents you need for the test — your proof of residency, proof of identity, and proof of Social Security number.

How to reschedule or cancel using your reference number

If you need to change your test date, log into your state's DMV website or call the DMV's scheduling line and have your reference number ready. Most states let you reschedule online if you do it at least a few days before your appointment — the exact notice period varies by state. You'll enter your reference number to pull up your appointment, then select a new date and time from available slots.

If you're cancelling instead, the process is similar: use your reference number to locate the appointment, then select the cancellation option. Some states charge a cancellation fee or require you to wait a certain number of days before rebooking. Check your state's DMV website for its specific cancellation and rescheduling rules before you contact them.

What happens if you lose your reference number

Contact your state's DMV directly — by phone, online chat, or in person — and provide your full name, date of birth, and either your driver's license number or learner's permit number. The DMV staff can search their system for your upcoming test appointment and give you the reference number over the phone or in writing. This usually takes just a few minutes.

If you're calling, have your ID ready so you can answer security questions. If you're visiting in person, bring your learner's permit or ID. Some states also let you retrieve your reference number by logging into your DMV account online if you've already created one.

Reference numbers by state

The name and format of your reference number depends on which state you're testing in. California calls it a confirmation number and formats it as a series of letters and numbers. Texas uses an appointment number. New York refers to it as a test ID. Florida calls it a confirmation code. The exact format varies, but every state's DMV issues one when you book.

If you're unsure what your state calls this number or how to find it, visit your state's DMV website and search for "test confirmation" or "appointment number." Most state DMV sites have a dedicated page explaining what information you'll receive when you book and what to bring on test day. You can also call your state's DMV customer service line — the number is on the DMV website — and ask them to explain what your confirmation document should include.

Frequently Asked Questions

Do I have to bring my reference number to the test, or is the confirmation email enough?

Bring the confirmation document itself — either printed or on your phone — rather than just memorizing the number. The testing office may scan it or need to see it to verify your appointment. Having the full confirmation is safer than relying on memory.

What if my reference number doesn't match the one on my confirmation email?

Contact your state's DMV when ready. There may be a data entry error, or you may have booked two appointments by mistake. The DMV can clarify which appointment is active and which reference number is correct before your test date.

Can I use my reference number to check if I passed my test?

No — your reference number identifies your appointment, not your results. After you test, you'll receive your pass or fail result on a separate document from the testing office. Some states let you check results online using your driver's license number or learner's permit number, but not your test reference number.

How long is my reference number valid?

Your reference number is valid until your test appointment date. After you test, it's no longer used. If you reschedule, you'll receive a new reference number for your new appointment date.

What if I booked my test by phone and didn't get a confirmation number?

Call the DMV back and ask them to provide your confirmation number or reference number for your appointment. Have your name, date of birth, and learner's permit number ready. They can look it up in the system and either give it to you over the phone or send it by email.
