Your first weeks in Sweden: personnummer and the essentials

The personnummer is your Swedish personal identity number, issued by Skatteverket when you are entered into the population register. It takes the form YYYYMMDD-XXXX, is unique to you, and stays with you for life, even if you later move abroad. It is the thread that runs through almost every interaction with Swedish society, which is why so little works smoothly until you have one.

The core condition is duration: you must intend to live in Sweden for at least twelve months to be registered in the population register. For non-EU/EEA citizens, that means holding a valid residence permit when you notify Skatteverket — in practice, a permit covering a year or more. EU/EEA citizens register on the basis of their right of residence, and Nordic citizens on the basis of intending to live in Sweden for at least a year. Family members who move with you, including children, register in the same way.

You begin online, with Skatteverket's "Moving to Sweden" notification, uploading your documentation — your passport and, for non-EU/EEA citizens, your residence permit card from the Migration Agency. You then complete the process in person with an identity check at a state service centre, bringing your passport and, where relevant, certificates for marriage and for any children. Once Skatteverket has processed the registration, it enters you in the population register, assigns your personnummer, and sends the decision to your registered address — so it is worth making sure that address is correct and stable before you file.

For a stay shorter than a year, you are generally not entered in the population register. A coordination number (samordningsnummer) may be assigned at an authority’s request, or you can apply if you meet the requirements. It helps authorities and employers identify you for matters such as tax, but it does not itself establish a right to healthcare, banking, or a Swedish ID card. If your circumstances change and you will live in Sweden for at least a year, notify Skatteverket so it can assess population registration.

A personnummer makes many services easier to arrange, but it does not automatically grant them. You apply separately for a Swedish ID card at Skatteverket, in person and for a fee. Your bank decides whether you meet its BankID requirements. Healthcare entitlement and social-insurance coverage depend on the relevant rules, so use 1177 and Försäkringskassan for your situation. School and childcare registration are also separate steps.

Register your move promptly and keep your address current. Check your driving licence early: most non-EEA licences cease to be valid after one year of population registration, but UK and Faroe Islands licences are exceptions, and exchange rules differ by issuing country. The relevant date is your registered residence date, not the day the personnummer letter arrives. Ask Transportstyrelsen about exchange or an exemption before the deadline. If you need banking before your Swedish ID card arrives, ask the bank about acceptable identification and bring your passport, employment contract, and address documentation. A personnummer is not by itself a legal requirement for a basic payment account for an eligible EEA resident.
