Finnish Personal Identity Code (Henkilötunnus) Guide

The henkilötunnus (personal identity code) is the single number that unlocks nearly everything in Finland. Banking, healthcare, taxation, employment, and almost every government portal depend on it. Yet newcomers routinely arrive expecting to "just get one" and discover that the route depends on their nationality, that an in-person identity check is usually required, and — most confusingly — that holding the code is not the same as being entitled to public services. This guide explains what the henkilötunnus is, exactly how to obtain it as an EU or non-EU arrival, the documents and timelines involved, and the traps that delay people most. Sort this out early: it is the foundation everything else is built on.

What the Henkilötunnus Is

The henkilötunnus (often abbreviated HETU — "personal identity code") is an 11-character identifier that uniquely names you in Finland's Population Information System. It is not a card or a document in itself; it is a number that then appears on your Finnish identity card, residence permit card, Kela card, and across official records. Once assigned it is permanent and stays with you for life.

The format is DDMMYY + an intermediate character + a three-digit individual number + a check character, for example 131052-308T:

• DDMMYY — your date of birth (day, month, two-digit year).
• Intermediate character — encodes the century of birth and also separates the two halves of the code (more on this below).
• Individual number (three digits) — distinguishes people born on the same day.
• Check character — a final digit or letter derived by a modulo-31 calculation over the preceding nine characters, used to catch typing errors.

The 2023 Format Reform — Why You May See Unfamiliar Letters

Historically the intermediate character was simply + for people born in the 1800s, - for the 1900s, and A for the 2000s, and the individual number signalled sex (odd for men, even for women). Two reforms changed this:

• From 2023, new intermediate characters were introduced because the supply of codes for some birth dates was running low. For 1900s births the letters Y, X, W, V and U now exist alongside the familiar hyphen; for 2000s births B, C, D, E and F join the existing A. So a code beginning 131052X is just as valid as one with a hyphen. This was confirmed by DVV and the Finnish Government.
• From 2027, the individual number will no longer indicate sex, as part of removing gender information from new codes. Crucially, existing personal identity codes are not changed by either reform — your number stays exactly as issued.

You do not need to memorise these characters, but it helps to recognise that a code with a letter where you expected a hyphen is normal and not an error.

Who Issues It — DVV and Migri

The Digital and Population Data Services Agency (DVV — Digi- ja väestötietovirasto) is the authority that issues the henkilötunnus and maintains the Population Information System — the Finnish equivalent of Norway's Folkeregisteret or Denmark's CPR register. DVV's foreigner pages are at dvv.fi/en.

There are two practical routes to a code:

1. Through Migri (the Finnish Immigration Service) with your residence permit. Since 1 February 2019, if you are granted a residence permit, register an EU right of residence, or otherwise gain the right to reside, your details are in most cases registered automatically — and you receive a henkilötunnus without a separate application.
2. Directly with DVV if a code was not assigned automatically, or if your route did not involve Migri. This is the in-person registration process described below.

Which route applies to you depends mainly on whether you are an EU/EEA citizen or not.

Who Is Eligible

You can receive a full henkilötunnus if you are residing legally in Finland and plan to stay for one year or more. Recognised legal grounds include:

• A valid residence permit issued by Migri (non-EU/EEA citizens).
• A residence card or registration certificate confirming an EU/EEA or Swiss citizen's right of residence.
• Other grounds recognised by Finnish law.

If your stay will be shorter than a year, you may instead qualify only for a foreigner's identity number — covered near the end of this guide.

EU/EEA and Swiss Citizens

EU, EEA, and Swiss citizens do not need a residence permit to live in Finland. However, if you intend to stay longer than three months you must register your right of residence with Migri. Once that is done, you are eligible for a henkilötunnus through DVV.

The convenient part: if this is your first time registering in Finland, you can usually apply for the henkilötunnus and register with DVV at the same time, rather than treating them as two separate trips. Bring your EU registration certificate (or proof you have applied for it) to your DVV appointment.

Non-EU/EEA Citizens

If you are from outside the EU/EEA, you need a valid residence permit before you can be registered and receive a henkilötunnus. Apply to Migri (often through the Enter Finland online service) before or upon arrival, depending on your nationality and permit category.

Here is the time-saver: because of the automatic process in place since February 2019, a henkilötunnus is in most cases assigned at the same time your permit is granted — provided three conditions are met:

• your application has been approved;
• you are not already registered in the system; and
• a Finnish authority has verified your identity.

That identity check is why the spelling of your name and the details on your application must exactly match your passport — Migri builds the record from your travel-document data. If automatic registration is not possible, you simply request the code from DVV after you arrive, using the in-person process below.

How to Apply Directly with DVV

If you are not assigned a code automatically, register with DVV yourself. The process is free of charge.

Step 1: Submit the Online Form

Start at dvv.fi/en/foreigner-registration, which links to the registration form at lomakkeet.dvv.fi. No login or strong authentication is required to submit it. You provide your personal details, your reason for staying in Finland, and contact information. Parents submit one separate form per child under 18. (A paper form exists if you genuinely cannot use the online one.)

Step 2: Book and Attend an In-Person Appointment

After submitting the form, book an appointment at a DVV service point and attend within one month. When booking you choose:

• Book for one person if registering only yourself.
• Book for multiple people or a family if there are 2–5 people; for six or more, book two appointments.

Everyone being registered must attend in person, including children — there is no way around the identity verification.

Step 3: Bring the Right Documents

Take with you:

• Valid passport or official EU/EEA photo ID card.
• Residence permit card (non-EU) or EU registration certificate — or proof you have applied for one.
• Proof of legal grounds for staying: employment contract, study acceptance/enrolment certificate, or equivalent.
• Proof of a Finnish address if you have it: a rental agreement, or confirmation from your employer or university.
• For family relationships, bring legalised and translated certificates (marriage, birth) where relevant.

Step 4: Wait for Processing

DVV processes the request after your visit. According to DVV, expect roughly:

• Work and study applications: about 2–3 weeks.
• Other applications: about 3–4 weeks.

These are typical times as of 2026 and shift with demand — check the current estimate on dvv.fi. DVV notifies you when your code is assigned.

The Trap: Code vs Municipality of Residence (Kotikunta)

This is the single most common misunderstanding, so treat it as a separate fact: having a henkilötunnus is not the same as having a municipality of residence (kotikunta — "home municipality"). The personal identity code identifies you; the kotikunta status is what entitles you to subsidised municipal and wellbeing-county services — most importantly public healthcare at standard client fees, and day care.

Both DVV and Migri are explicit that getting a code does not automatically give you a kotikunta. You apply for the municipality of residence separately with DVV, and eligibility depends on factors like the nature and length of your stay. If you register in person with DVV, raise the kotikunta question at the same appointment so you do not leave thinking you are covered for healthcare when you are not. For the wider registration picture, see our guide to registering with DVV.

What You Can Do Once You Have It

A henkilötunnus is the key that turns on the rest of the system. With it you can:

• Open a bank account at a Finnish bank (Nordea, OP, S-Pankki, Danske Bank). See opening a bank account in Finland.
• Get a tax card (verokortti) through OmaVero / vero.fi — covered in our Finnish tax card guide.
• Register with Kela for social insurance and the Kela card, where eligible.
• Use Suomi.fi, the public services portal, once you have strong e-identification.
• Obtain online bank credentials (pankkitunnukset) — the de-facto national e-ID for logging into government and banking services.
• Access public healthcare at a health centre (terveyskeskus) — provided you also have a kotikunta.
• Enrol children in school or day care.

A practical note on the chicken-and-egg gap many face: you often need the henkilötunnus before a Finnish bank will open a full account, but you may need a way to receive salary or pay rent in the meantime. A multi-currency account such as Wise or Revolut is a common bridge for those first weeks — useful as interim cover, not a permanent replacement for a Finnish account once your code comes through.

The Foreigner's Identity Number: A Limited Alternative

If you do not qualify for a full henkilötunnus — most often because your stay is under a year — you may be assigned a foreigner's identity number (ulkomaalaisen tunnistenumero — "foreigner's identification number"). This lets authorities such as Migri and the Tax Administration identify you and lets you meet tax obligations, but it is not equivalent to a full henkilötunnus: it does not unlock the full range of public services, and most banks and private providers will still ask for the full code. If your circumstances change and you extend your stay beyond a year, you can then apply for a full henkilötunnus.

Common Problems and Fixes

• "My permit was granted but I never got a code." Automatic issuance needs your identity to have been verified by a Finnish authority and your details to match your passport exactly. If it did not happen, request the code from DVV in person after you arrive — do not wait for it to appear on its own.
• "I have a henkilötunnus but the health centre says I'm not covered." You almost certainly have the code but not a kotikunta. Apply for the municipality of residence with DVV; until then, non-emergency public care may not be available at subsidised rates.
• "My name is spelled wrong / my date of birth is incorrect." Errors trace back to the source documents and identity check. Contact DVV to correct registered details; in narrow cases the code itself can be changed (e.g. wrong date of birth recorded).
• "I couldn't get a DVV appointment within a month of submitting the form." Appointment availability varies by city and season. Book as early as you can; if slots are scarce, check service points in nearby municipalities and the booking system at different times of day.
• "A bank refused me because I only have a foreigner's identity number." That is expected — it is not a full henkilötunnus. Use a Wise or Revolut account as interim banking, and apply for the full code once you qualify.
