The Central Person Registry


Primary variables

Address data

Birth registration place


Civil status


First name(s)

Guardianship data

National church - details



The Central Personal Registry (CPR) holds data on all individuals who have been living in Denmark after 2 April 1968 and who have been registered with a Danish municipality. Individuals from Greenland were added later on 1 May 1972. However, individuals from the Faroes are not listed in the CPR. The relationship between parents and children is defined administratively, so adopted children are registered as for all others.

The CPR is a central provider of personal data to the public authorities and the private sector. The actual register consists of multiple sub-tables established for administrative purposes. For research purposes, this could be significant since the focus is on administrative use and not research. For example, the tables are split into current and historic records and not all data is retained in the historic tables.

The data contained in the CPR system is currently used to update a whole range of public registers and IT systems containing personal and road data. The CPR Office is responsible for operating the CPR register whilst the Statens Serum Institutee operates a shadow registry that is intended among other things to service researchers via the researcher service unit.
