Det Centrale Personregister (CPR; English: Civil Registration System) is Denmark's nationwide civil registry. Established in 1968, the registry contains the name, address, Danish personal identification number, date and place of birth, citizenship and other information on all the country's citizens and residents. Virtually every government agency in Denmark receives information about a person from this database.
The register is housed by CPR-Kontoret (literally "The CPR Office"), which is responsible for maintaining and developing the database and communicating data to government agencies, as well as to authorised private companies.
Anyone living in Denmark must register after 3 months (6 months if they are a citizen of a Nordic Council country). Every person registered in this database can request a free printout of his or her record.
The Danish state also runs Det Centrale Virksomhedsregister (CVR; English: Company Registration System), which is a register over Danish companies, with each company being issued a unique CVR-number.
