Australian passport number format
An Australian passport is a travel document issued by the Commonwealth of Australia to individuals holding any form of Australian nationality. The document is issued by the Australian Passport Office, an agency of the Department of Foreign Affairs and Trade (DFAT). Since 24 October 2005, Australia has issued only biometric passports, known as ePassports, which have an embedded microchip that contains the same personal information that is printed on the colour photo page of the passport, including a digitised photograph.
The Australian passport has gone through several series, with the latest being the R Series, which was first issued in September 2022. The R Series passport combines visual elements and advanced technologies, including a polycarbonate photo page, which is more durable than laminated paper and prevents damage that can cause difficulties when crossing borders. The R Series also includes a transparent window with a second coloured photo of the passport holder, as well as other windows that include the antenna for the passport chip.
Under ultraviolet light, other security features of the R Series passport become visible. The photo page turns bright red, and a red and white wattle is visible on the inside front cover. The visa pages, which feature 17 iconic Australian landscapes, also transform under UV light, with the sky in each landscape becoming a unique nightscape and a local species of native fauna appearing.
The exact format of the Australian passport number is not publicly available, however, it is known that the passport number is stored on the embedded microchip, along with the owner's digitised photograph, name, sex, date of birth, nationality, and passport expiry date. This is the same information that appears on the printed information page of the passport.

Passport number security
An Australian passport is a highly secure document, with a range of features designed to prevent counterfeiting and identity theft. Since 2005, Australia has issued only biometric passports, called ePassports, which have an embedded microchip containing the same personal information as the colour photo page, including a digitised photograph. The photo page is made from polycarbonate, which is more durable than laminated paper and prevents minor damage that can cause difficulties when crossing borders.
The passport number itself is a unique identifier, like a fingerprint, tying the document to its owner. It is protected under the Privacy Act and is not considered public information. However, travellers often share their passport numbers when booking international flights, checking into hotels, or verifying their identity with institutions. This means that there is a risk of data breaches, with Marriott hotels suffering a significant breach in 2019 which exposed 5.25 million unencrypted passport numbers.
To protect yourself from identity theft, it is important to keep your passport in a secure location and to be vigilant when sharing your passport number. Be cautious of bogus passport renewal websites and only input information via official channels. Be aware of phishing attempts and 'shoulder surfing', where thieves look over your shoulder to steal your details. If your passport is lost or stolen, report it immediately to prevent fraudulent use.
The Australian government takes passport security seriously, with the latest R Series passports incorporating advanced technologies and Indigenous artwork. The R Series includes a raised map of Australia, a transparent window with a second coloured photo of the passport holder, and other windows that contain the antenna for the passport chip. Under ultraviolet light, the visa pages display unique nightscapes and native fauna, and the photo page turns bright red. These features ensure that Australian passports are highly secure and difficult to forge.

Passport number recognition
An Australian passport number is part of a wide range of security features that aim to prevent counterfeiting and identity theft. Since 24 October 2005, Australia has issued only biometric passports, known as ePassports. These passports contain an embedded microchip that holds the same personal information as the colour photo page, including a digitised photograph.
The passport number is one of the pieces of information that can be used to verify the authenticity of a passport. This process is crucial for maintaining security and preventing identity fraud, illegal immigration, and other fraudulent activities. Passport verification has evolved with the use of advanced technologies based on artificial intelligence, allowing for remote verifications.
The verification process involves detecting holograms or watermarks, determining if the document is a photocopy, checking for digital alterations, and validating the control digits of the MRZ. For passports with an NFC chip, verification also includes confirming the authenticity of the information and the chip itself. This can be done via Near-Field Communication (NFC) technology, where the chip can be scanned to confirm the information on the passport and verify its authenticity.
In addition to the above, biometric verification may be employed, using facial recognition algorithms to match the passport holder's photograph with a real-time image provided by the individual. This can be done via a selfie taken on a webcam or mobile device, ensuring that the person presenting the passport is the rightful owner.
Overall, the Australian passport number is an important component of the passport's security features, and its verification is a critical step in maintaining the integrity of international travel and remote identity verification processes.

Passport number uses
An Australian passport number is comprised of two letters (PA, PB, PC, PD, PE, PF, PU, PW, PX, or PZ) followed by seven digits. The passport number is part of a broader system of security features that aim to prevent counterfeiting and identity theft.
Passport numbers are used for identification and security purposes. They are unique to each passport holder, and act as a primary identifier for individuals when they are travelling internationally. When boarding a plane, for example, airlines will often ask for a passport number, and this is also the case when entering or exiting a country. This is because the passport number is linked to other personal information, such as name, date of birth, and nationality, which is all stored on the passport's embedded microchip.
The passport number is also used to track the progress of a passport application. When an individual applies for a passport, they are given an application number, which can be used to check the status of their application. This number is different from the passport number, which is unique to the physical passport document.
In addition, passport numbers are used to report lost or stolen passports. When a passport is lost or stolen, the holder must report the details to the Australian Passport Office, who will cancel the passport to prevent it from being misused. The passport number is also used when an individual wants to keep their cancelled passport as a memento.
For dual nationals, the passport number is especially important. If a dual national travels on a foreign passport, local authorities may not recognise them as an Australian citizen. This can limit the Australian government's ability to provide consular assistance. Therefore, it is recommended that dual nationals always enter and leave Australia using their Australian passport.
