You do not apply for a personnummer, Sweden's personal identity number, directly. Skatteverket, the Swedish Tax Agency, assigns it once you clear an eligibility test. That test belongs to folkbokföring, Skatteverket's population-registration process. Many readers conflate living in Sweden with qualifying for one. The test instead proves intent to stay one year or more, and Skatteverket asks for different evidence depending on your citizenship. This guide walks through which branch applies to your case, what evidence Skatteverket wants for it, and what happens if your stay falls short of a year.
The One-Year Test Skatteverket Actually Applies
Skatteverket registers you in the Population Register, and assigns a personnummer, once you have moved to Sweden and plan to live there for one year or more. This registration process is folkbokföring, Skatteverket's population-registration system. Folkbokföring is the gate; the personnummer is its byproduct, not a separate application you file on your own.
Per Skatteverket's "Moving to Sweden" guidance, you should be listed in the Population Register once you have moved to Sweden and plan to live here for one year or more. The same underlying test applies to everyone who moves to Sweden. Skatteverket proves it on different evidence depending on your citizenship, summarized below and detailed in the next two sections.
| Your citizenship | Evidence you provide | Who assesses it |
|---|
| Non-EU/EEA | Migrationsverket residence permit valid at least 12 months | Skatteverket, checking the permit Migrationsverket already issued |
| EU/EEA | Employment, self-employment, study, or sufficient means (uppehållsrätt) | Skatteverket, directly, with no Migrationsverket permit involved |
Non-EU/EEA Citizens: Proving the Year With a Permit
If you hold citizenship outside the EU or EEA, you meet the test by holding a valid Swedish residence permit, uppehållstillstånd, from Migrationsverket that covers at least 12 months. Per Skatteverket's guidance for non-EU/EEA citizens, Skatteverket checks your residence permit card at your notification appointment. It also checks proof of identity, your reason for moving, your full residential address, and proof of your family situation where relevant.
A permit issued for under a year does not clear the test. If your permit runs shorter than 12 months, Skatteverket points you toward a samordningsnummer instead, covered further down this page. Bring your passport or another official identity document to the appointment, along with an employment contract, enrollment certificate, or your Migrationsverket approval letter as evidence of why you are moving. Your name must already appear on the door or postbox at your registered address. See Permits for the permit decision that comes before this test.
EU/EEA Citizens: Right of Residence, Not a Permit
If you hold EU or EEA citizenship, you meet the test through your own right of residence, uppehållsrätt, proven by employment, self-employment, study, or sufficient means to support yourself. You can also qualify as the family member of someone who already holds that right. Migrationsverket issues no permit for this route at all.
Skatteverket, not Migrationsverket, assesses this branch directly, per its own guidance for EU/EEA citizens. This is a materially different test from the non-EU/EEA permit-length check, even though both are popularly called "the one-year rule." See Finding Work for an employment contract as proof of self-sufficiency, or Studying in Sweden for study enrollment as proof of self-sufficiency.
Staying Under a Year: The Samordningsnummer Detour
If you do not plan to stay a year, you apply for a samordningsnummer instead of registering through folkbokföring. Per Skatteverket's coordination numbers guidance, a samordningsnummer is issued only to someone who is not currently, and has not previously been, folkbokförd in Sweden.
The moment its holder is later folkbokförd, the samordningsnummer is replaced automatically by a personnummer, with no separate application required. The two numbers are easy to confuse on sight, but one format detail tells them apart. A samordningsnummer adds 60 to the day-of-birth digits; a personnummer never does, since no month runs past 31 days. A person born on the third of the month carries "03" in a personnummer and "63" in a samordningsnummer. That offset is a fast check for which number type you hold.
Children Born in Sweden: When the Test Passes to a Parent
A child born in Sweden is assigned a personnummer only if one parent already holds a place in the Population Register at the time of birth. That parent can be the one who gave birth, or the other legal guardian. This is per the Nordic Council of Ministers' guidance on the Swedish personal identity number. The standard path runs through the hospital: a midwife reports the birth directly to Skatteverket, and no separate application follows.
A home birth without a midwife present works differently. The guardians must report the birth to Skatteverket in writing within one month, providing supporting documentation, per Skatteverket's "Nybliven förälder" (new parent) guidance. Neither condition may be met: the parent who gave birth is not registered, and no other guardian is registered in their place. In that case, the child is not registered and receives no personnummer. If your own registration status as a parent is unresolved, see Partner and Family Permits for family and partner permit routes.
What Happens Once Skatteverket Approves the Test
Clearing the test does not end the process at the personnummer. It is the first of several identity gates you still have to clear. Folkbokföring assigns the personnummer, but the number alone does not yet unlock a bank account, an ID card, or BankID. Each of those sits behind a separate institution's own process. See the personnummer, ID card and BankID sequence for the steps that follow once your number arrives.
Frequently Asked Questions
Does a Residence Permit Valid for Exactly 12 Months Meet the One-Year Test?
Yes, if you are a non-EU/EEA citizen. Skatteverket's guidance ties eligibility to a Migrationsverket residence permit card valid for at least 12 months, and a permit covering exactly that length clears the threshold.
What Happens to a Samordningsnummer Once Folkbokföring Is Granted?
It is replaced automatically by a personnummer. No separate application is needed; the conversion happens as part of the same folkbokföring decision that registers you.
Is a Child Born in Sweden Automatically Assigned a Personnummer?
Only if the parent who gave birth, or the other legal guardian, is already listed in the Population Register at the time of birth. If neither condition is met, the child is not registered.
Do EU/EEA Citizens Need a Residence Permit Before Registering?
No. EU/EEA citizens qualify through their own right of residence, uppehållsrätt, proven through employment, self-employment, study, or sufficient means. Migrationsverket issues no permit in this branch, and Skatteverket assesses the right of residence itself.
The Test Splits by Citizenship, Not by a Single Rule
The personnummer follows folkbokföring; you do not request the number on its own. The one-year test behind that registration is proven differently depending on your citizenship: a Migrationsverket permit length for non-EU/EEA citizens, your own right of residence for EU/EEA citizens. Staying under a year routes you to a samordningsnummer instead, and a newborn's eligibility depends on a parent's registration status at the time of birth, not the birth itself.
Resolve whichever branch applies to you first: see Permits if your case turns on permit length, or Partner and Family Permits if it turns on a family relationship. Once your personnummer is assigned, the personnummer, ID card and BankID sequence covers what to do next.
