Data properties​

Here you can find more in-depth information about the attributes for ID Austria.

bPK​

bPK stands for bereichsspezifisches Personenkennzeichen. This is an area-specific personal identification number.

The bPK is a unique ID (subject) for a person authenticating to your service. It is designed to protect privacy. Because the bPK is different for each service, companies cannot use it to track a user's activity on other websites. This prevents any single organisation from building a complete profile of an individual's digital life.

The bPK is encoded using the Base64 standard. It contains a base user number, your organisation's registration number, and an area code. An example of a bPK is XNV5ThCj5OwJR0oOcWmK4WUs5p4=. The format is 28 characters long with ISO-8859-1 for the area code.

ID Austria level​

The ID Austria level tells you how a user's identity was checked. Think of it as a trust score for their identity.

There are two main levels:

  • Full: A very trustworthy identity level. It means the user proved who they are in person, using an official photo ID like a passport.
  • Basic. A less secure identity level because users might have registered online without the same strong checks in person.

Knowing the level helps you decide if a user's identity is secure enough for the action they want to take.

ID Austria lets a person act on behalf of a company or another person. This is called legal representation. This feature is suitable for delegated business and legal tasks.

For example, a director can use their own ID Austria to sign documents for their company. When this happens, the data will include details about who is being represented. Attributes like Name des vertretenen Unternehmens (Represented company name) will be filled in. You need to check for these attributes to understand in what role the user is acting.

Vehicle registration data​

This attribute (Zulassungsscheindaten) gives you detailed information about a user's registered vehicles, such as licence plate number, vehicle specifications, and registration dates. The data comes in a structured JSON format from the official vehicle register.

You may use this information when you want to handle insurance, vehicle sales, or company cars since it comes from an official source.
