Goal and impact

The aim of LAA is to improve the quality of address data in the BRP. This will enable public bodies to perform their public tasks based on accurate information. This is done by analysing personal data using risk profiles. The Ministry of the Interior and Kingdom Relations processes the data.

If, after investigation, it turns out that the registration is incorrect, the municipality notifies the resident in writing. A formal process then follows: the address investigation. The resident is asked to report his/her change of address as soon as possible. If the municipality has found out the correct address, the municipality will administratively move the resident to this address. If the municipality could not trace an address, the resident will be deregistered from the BRP. It is then unknown where the resident resides. The municipality records in the system that the address is unknown.

When investigating the registration of persons at the address, a home visit is made to the address.

Considerations

LAA is a collaboration of public organisations, including municipalities, various ministries and implementing organisations. Together, we work to identify and rectify incorrect address data in the BRP. We also cooperate with organisations such as the Dutch Association for Civil Affairs (NVVB), Divosa and VNG Compliance. As a result, the quality of entries in the BRP and its consequences are looked at from different interests and knowledge fields, so that LAA's efforts benefit society as much as possible.

Human intervention

Advisory. The Address Investigation Department investigates reports. Each signal is assessed manually/independently. The department assesses independently/manually whether further investigation is necessary.

Risk management

Privacy is potentially compromised, through the processing of personal data and home visits by municipalities.

The signals are provided by (RVIG). The RVIG tests whether all signals are compliant.

The system (LAA Monitor) where data is exchanged meets all municipal security requirements. Data is exchanged via eHerkenning (Link to external page https://eherkenning.nl/nl).

There is no automated decision-making. Each signal investigated is assessed manually.

If signals are older than 6 months, they are removed from the LAA Monitor. If an LAA investigation reveals incorrect data, an official address investigation follows (signal category 08 listed on the citizen's personal record). The complete file (report from the LAA monitor) is then part of the official address investigation. This investigation is kept for 10 years (legal retention period for address investigations).

Data

The data from the Basic Registration of Persons (BRP) such as number of people registered at an address and the data from the Basic Registration of Addresses and Buildings (BAG) such as living area per address and the function and status of the address.

Regulations state which data we are allowed to use in the algorithm. Data that is not mentioned is therefore not allowed to be used. Nor do we use (personal) data that could lead to discrimination. We do not select on nationality, place of birth or derivatives thereof.

Technical design

Municipalities, police and government departments such as the Tax Office and the Central Judicial Collection Agency sometimes receive signals indicating incorrect address registration.

For example:

- too many occupants per square metre;

- mail returned to the sender;

- an abnormal composition of a household at an address.

The signals are shared with the Information Exchange (IKP), which analyses them and makes them suitable for possible investigation by municipalities. The IKP also complements the information from participating organisations with data obtained from other (basic) registries. The data is processed into risk-oriented signals for address research. The municipality can use these signals to start an investigation and, for example, conduct a home visit. In this way, the municipality determines whether the address data are correct.

Municipal employees can then conduct risk-oriented address research and, where necessary, correct the address data in the BRP.
