How to get a CPR number in Denmark

Without a CPR number in Denmark, authorities don’t know you exist. You can’t open a bank account, you can’t be paid correctly by your employer, and you can’t access the public healthcare system. It’s the thread that holds every Danish public system together — and getting it is one of the first things you need to do after arriving.

The process is fairly straightforward once you understand what’s required for your nationality. The frustrating part, which catches most new arrivals off guard, is the address catch-22: you need a Danish address to register, but many landlords want a CPR number before they’ll sign a lease. More on that below.

What Is a CPR Number?

CPR stands for Det Centrale Personregister (Central Person Register). It’s a unique 10-digit identifier in the format DDMMYY-XXXX — your date of birth followed by a four-digit sequence. Denmark has maintained this register since 1968. Every resident, past and present, is in it.

Think of it as a Social Security Number, a National Insurance Number, and a tax file number rolled into one — except Denmark uses it for everything: healthcare, banking, utilities, digital services, even the library. Once you have it, the rest of your administrative setup becomes possible.

(A minor detail worth knowing: the final digit indicates registered sex. Odd for men, even for women.)

Why You Can’t Function Without One

Here’s what you can’t do until you have a CPR number:

• Open a Danish bank account
• Get a tax card and be paid correctly by your employer
• Access the public healthcare system (GP, hospital, prescriptions)
• Receive your yellow health insurance card (sundhedskort)
• Set up MitID — your digital identity for online banking, SKAT, e-Boks, and all government services
• Sign most rental leases
• Get a phone contract
• Register for utilities, childcare, or school enrolment
• Receive Digital Post from public authorities

Denmark is one of the most digitised countries in the world. MitID alone unlocks your bank, your tax affairs, and most government services. Getting your CPR number is your first administrative priority after arriving.

Who Can Get a CPR Number?

Three conditions apply to everyone:

• You need a Danish address. A registered address — rental contract, sublet, or ownership — is mandatory. You can’t register without one.
• You must plan to stay for more than three months. Shorter stays don’t qualify for CPR registration.
• Non-Nordic citizens need a residence document. EU/EEA/Swiss citizens need an EU residence document from SIRI. Non-EU citizens need a residence permit from SIRI or the Danish Immigration Service. Nordic citizens can skip this step entirely.

The Process, Step by Step

The route depends on your nationality. Here’s how each group approaches it.

Nordic citizens (Norway, Sweden, Finland, Iceland)

The simplest path. No residence document needed. Once you have a Danish address and plan to stay more than three months:

• Submit an online CPR application through your municipality’s website or International Citizen Service (ICS).
• Wait for an invitation email to book an in-person appointment. Typically 1–3 weeks.
• Attend with your passport or national ID, proof of address, and your home country social security number.
• Receive your CPR number at or shortly after the appointment.

EU/EEA/Swiss citizens

You need to complete two separate steps in a specific order. This catches a lot of people off guard.

Step 1: Get your EU residence document from SIRI. Before applying for a CPR number, you must first obtain an EU residence document from the Danish Agency for International Recruitment and Integration (SIRI). This confirms your right to reside in Denmark under EU law. You apply through SIRI’s online system, then attend an in-person SIRI appointment. If your documents are in order, you can receive it on the day. You’ll need to demonstrate your basis for being in Denmark: employment contract or payslips, university admission letter, self-employment evidence, or proof of sufficient funds.

Step 2: Apply for CPR registration. Once you have your EU residence document (valid, no older than six months), you can apply for CPR registration. Submit the online application through your municipality or ICS, wait for the invitation email, attend the in-person appointment with your passport, residence document, and proof of address, and receive your CPR number.

Non-EU/EEA citizens

Your process depends on having an approved residence permit first.

• Apply for and receive your residence permit from SIRI or the Danish Immigration Service (Udlændingestyrelsen) via nyidanmark.dk. Processing times vary widely: a few weeks for fast-track work permits, several months for family reunification. You need the permit or approval letter in hand before any CPR steps.
• Submit your online CPR application through your municipality or ICS, uploading your passport and residence permit.
• Wait for the invitation email and book your in-person appointment.
• Attend the appointment with your passport, biometric residence card, proof of address, and any family documents.
• Receive your CPR number at or shortly after the appointment.

What Documents to Bring

Requirements vary slightly by municipality. Bring originals of everything. Uploads during the online application don’t substitute for physical documents at your appointment.

How Long Does It Take?

Timelines vary by nationality, municipality, and time of year. Late summer and January are peak periods — expect slower processing in Copenhagen and Aarhus during these months.

For a Nordic citizen with everything ready, the whole process can take as little as 1–2 weeks. For an EU citizen starting from scratch (SIRI appointment, CPR application, CPR appointment), expect 3–6 weeks in total. For non-EU citizens, the timeline is almost entirely dictated by how long the residence permit takes.

The Address Problem

Here’s the catch-22 that frustrates nearly every new arrival: you need a registered Danish address to get a CPR number, but many landlords want a CPR number before they’ll sign a lease.

There’s a secondary complication too. Municipalities use the BBR (Bygnings- og Boligregistret, the Building and Housing Register) to check how many rooms a dwelling has. If too many people are already registered at an address relative to its size, the municipality can refuse CPR registration. There’s no hard cap — it’s a judgement call — but this occasionally catches people renting a room in a shared flat that’s already at capacity.

Most people navigate the address problem by:

• Having their employer help. Many Danish employers, particularly those hiring internationally, are experienced at helping new arrivals find initial accommodation or providing a corporate address for first registration.
• Using temporary accommodation that allows registration. Some serviced apartments and short-term rental companies — Housing Denmark, ZINN, LifeX — permit CPR registration. Always confirm before booking. Standard Airbnbs and hostels generally don’t.
• Using expat-oriented housing platforms. BoligPortal, Findroommate.dk, and HousingAnywhere tend to have landlords experienced with renting to internationals who don’t yet have a CPR number.
• Being cautious of scams. The desperation to find an address makes international newcomers a target. Never pay a deposit without seeing the property in person. If it looks too good to be true, it is.

What Happens After You Get Your CPR Number?

Several things become available immediately — or arrive automatically within a few weeks.

Yellow health card (sundhedskort). Arrives by post within 2–4 weeks. This is your proof of public health insurance and includes your assigned GP’s name and address. Carry it to every medical appointment.

MitID. Denmark’s digital identity system. You need it to log in to your bank, access SKAT, read Digital Post via e-Boks or borger.dk, and use virtually every public online service. In many municipalities you can set up MitID at the same appointment where you receive your CPR number. Otherwise, wait for your yellow health card first.

Tax registration. You’re automatically registered in the Danish tax system. Log in to skat.dk via MitID to view your tax card, adjust deductions, and manage your tax affairs. Read our complete guide to danish taxes here. 

Digital Post. All mail from public authorities is sent digitally, not on paper. It arrives in your e-Boks or Digital Post inbox via borger.dk. You’ll receive a physical letter explaining how to set it up.

GP assignment. You’re assigned a GP in your area. You can change GP (within your municipality) through borger.dk. Seeing your GP is free.

Bank account. With your CPR number, tax card, passport, and MitID, you can open a Danish bank account and set up your Nemkonto. See our separate guide on banking in Denmark for the full process.

What If You’re Only Here Temporarily?

If you’re staying less than three months, you can’t get a CPR number. But that doesn’t leave you in limbo:

• Working for less than 3 months: contact SKAT directly to get a tax number (skattenummer). This lets your employer withhold tax correctly and pay you legally.
• EU citizens can work immediately: you have the right to begin working as soon as you arrive, before you have a CPR number or EU residence document. Your employer and SKAT can handle the tax side.
• EU jobseekers: you can stay up to six months without a residence document while actively looking for work. Once you find a job and plan to stay beyond three months, begin the SIRI and CPR process promptly.
• Students on short exchanges: if your programme is under three months, you likely won’t get a CPR number. Your university can help with a tax number if you’re working part-time.

Practical Tips

• Start from abroad if you can. EU citizens can apply for their SIRI residence document online before arriving and attend the in-person appointment shortly after. Non-EU citizens should have their documents ready to go the moment their permit is approved.
• Your CPR number never changes. Even if you leave Denmark and return years later, your number is reactivated when you re-register.
• Book appointments early. In Copenhagen and Aarhus, slots fill up fast in September (start of academic year) and January. Smaller municipalities are often much quicker.
• Bring hard copies of everything. Even if you uploaded documents online, bring physical originals to your appointment.
• Put your name on your mailbox immediately. Your yellow health card is sent by physical post. If your name isn’t on the mailbox, it will be returned.
• Budget for the gap. The period between arriving and having your CPR number, yellow card, MitID, and bank account fully set up can be 4–8 weeks. Make sure you have access to home-country funds during this transition.
