What is a CPR number? Understanding Denmark’s unique identification system

What is a CPR number?

CPR stands for Central Person Register and is a unique identification and social security number assigned to every resident and citizen of Denmark. The number combines 10 digits, including the person’s birthdate, and a unique four-digit number.

The CPR system was introduced to streamline the country’s healthcare system - and the system has since expanded to include other government agencies and services.

The CPR number is essential to the Danish social security system, enabling the government to provide services efficiently. The system also plays a crucial role in correctly identifying individuals in various contexts, from healthcare to employment and banking.

What is the CPR number used for?

The CPR number is the primary identification number for all residents and citizens of Denmark. It’s used by government agencies, healthcare providers, banks, and for other purposes such as:

• Banking and financial transactions
  Banks use the CPR number to verify a customer’s identity and ensure that they are authorized to open a bank account in Denmark.
  
• Medical record keeping and healthcare services
  In healthcare, the CPR number is used to track an individual’s healthcare records through “the yellow card”, which will give you access to the national health insurance scheme.  
  
• Taxation
  You need a CPR number to pay taxes in Denmark, as it allows tax authorities to identify and track an individual’s tax liabilities.

The CPR number is also linked to various systems and services - such as the e-boks and Digital Post. Having a valid CPR number is also a prerequisite for using your NemKonto.

Obtaining a CPR number is one of the many steps you need to take when moving to Denmark. Read much more about moving to Denmark in our comprehensive guide here.

How to obtain a CPR number?

To obtain a CPR number, you must apply for it at your local Citizen Service Center (Borgerservice) or an International Citizen Service Center. Then you will receive your yellow health insurance card in the mail, which will take 2-3 weeks.

To be eligible for getting a CPR number, you must be a resident or citizen of Denmark with a legal right to reside in the country . You must also provide proof of identity and address, such as your passport information and/or a rental agreement or utility bill.

If you plan to stay for 3 months or more, the municipal authorities (Folkeregisteret) should be notified - and they will grant you a CPR number. Are you unsure, whether you need a CPR number or not? You can find a guide here that can help you determine if you need to apply for a CPR number.

Security and privacy of CPR data

You must protect your CPR information from identity theft and fraud. Here are some ways to always keep your information safe:

• Never share your CPR number with anyone who doesn’t have a legitimate reason to get it.
• Always be cautious when sharing personal information online - and always make sure to use it on secure websites.

If you suspect your CPR number has been stolen or misused, contact the Citizen Service Center immediately to report the issue and take appropriate steps to protect your identity.
