What your Australian driver license number tells you

Your Australian driver license number is a unique 10-digit code printed on the front of your physical license. It identifies you as a licensed driver in your state or territory and appears on every official record tied to your driving history. Unlike a name or address, this number never changes — it stays the same even if you renew your license, move states, or update your personal details.

The format is the same across all Australian states and territories, though the way the number is generated varies slightly by state. Understanding what each part means helps you read your own license and know what information authorities can see when they check your details.

Key Takeaways

  • Your Australian driver license number is a 10-digit code that uniquely identifies you as a licensed driver and never changes across renewals or state moves.
  • The first two digits represent your state or territory of issue, with codes like 01 for New South Wales and 03 for Victoria.
  • The middle digits encode your date of birth and surname, allowing authorities to verify your identity against your license record.
  • The final digit is a check digit calculated from the other nine, used to detect errors when your number is entered into a system.
  • Your license number is different from your driver license card number, which is a separate identifier printed on the back of your card.

The state or territory code (first two digits)

The first two digits of your driver license number identify which Australian state or territory issued your license. Each state and territory has its own code, and this code stays part of your number even if you move to another state and transfer your license.

The codes are: 01 for New South Wales, 02 for Victoria, 03 for Queensland, 04 for South Australia, 05 for Western Australia, 06 for Tasmania, 07 for Australian Capital Territory, and 08 for Northern Territory. Some older licenses may show different codes, but the current system uses these eight codes consistently.

The date of birth and surname section (digits three to nine)

Digits three through nine encode two pieces of information: your date of birth and the first letters of your surname. This section allows the licensing authority to verify that the person holding the license matches the person the number was issued to.

The date of birth is encoded using a specific algorithm rather than appearing as a straightforward date like 15/03/1985. The surname is also encoded, not spelled out. This encoding protects your privacy — a person looking at your license number alone cannot when ready read your full name or exact birth date without access to the licensing database.

The check digit (final digit)

The last digit of your 10-digit license number is a check digit, calculated mathematically from the nine digits before it. When your license number is entered into a government system or a police officer's database, the computer recalculates this check digit to confirm the number was typed correctly.

If you mistype even one digit, the check digit will not match, and the system will flag the entry as invalid. This catches straightforward data-entry errors before they cause problems with your driving record or vehicle registration.

Where to find your license number on your card

Your 10-digit driver license number appears on the front of your physical license card, usually in the top right corner or along the top edge. It is printed in large, straightforward-to-read digits and is the primary number you provide when asked for your license details.

Do not confuse this with the card number printed on the back of your license, which is a separate identifier used for card-specific transactions. When a police officer, employer, or government agency asks for your driver license number, they are asking for the 10-digit number on the front.

Why your license number matters

Your driver license number is the key to your entire driving record. It links you to your license class, any demerit points, traffic offences, medical conditions noted on your license, and vehicle registrations in your name. When you renew your license, transfer between states, or dispute a traffic fine, authorities use this number to pull up your complete history.

If you lose your license or it is damaged, you can report it using your license number, and the authority can reissue a replacement with the same number. This continuity means your driving history follows you — you cannot start fresh with a new number by getting a replacement card.

Transferring your license between states

If you move to another Australian state or territory, you can transfer your license to the new state's authority. Your 10-digit license number will change to reflect the new state code in the first two digits. For example, if you held a New South Wales license (01) and move to Queensland, your new number will begin with 03.

The transfer process requires you to surrender your old license and explore for a new one in your new state. You will need to provide proof of identity, proof of residency, and your current license. The new state's authority will issue you a new card with a new number, but your driving history transfers with you — the new authority can see your record from the previous state.

Frequently Asked Questions

Can I look up someone's driving record using their license number?

No. Only the person holding the license, their employer (if relevant to employment), insurance companies, and law enforcement can access driving records. A license number alone does not give you access to someone's history — you would need to be authorised by the licensing authority.

What happens if I give my license number to someone and they misuse it?

Report it to your state or territory's licensing authority when ready. They can flag your number in their system and investigate. If someone uses your number fraudulently, contact the police as well. Your license number is sensitive information — treat it like you would a bank account number.

Does my license number change if I renew my license?

No. Your 10-digit license number stays the same when you renew. The only time it changes is if you transfer your license to a different state or territory, which changes the first two digits to reflect the new state code.

Why is my license number different from my driver license card number?

The 10-digit license number is your primary identifier used by all Australian licensing authorities and law enforcement. The card number on the back is a separate identifier specific to that physical card. If your card is replaced, the card number changes, but your license number does not.

Can I request a different license number?

No. Your license number is assigned by the licensing authority based on the state code and your personal information. You cannot choose or change it unless you transfer to another state, which automatically generates a new number with the new state code.
