Sweden's 10-digit personal identity number — the master identifier for tax, healthcare, banking, and property registration. Essential for all expats living or working in Sweden.
The personnummer is Sweden's personal identity number, assigned by the Swedish Tax Agency (Skatteverket) to all persons registered as residents in Sweden. The number takes the format YYMMDD-XXXX, where the first six digits encode the date of birth and the last four are a serial number including a check digit. Once assigned, the personnummer is permanent and used across every part of Swedish public and private life — from tax returns and healthcare to opening a bank account and registering a property purchase.
For EU and EEA citizens moving to Sweden, the personnummer is obtained through the population register (folkbokforing). Register with Skatteverket in person, presenting your EU ID or passport and evidence of your right to reside — typically a Swedish employment contract, proof of self-sufficiency, or evidence of studies. Once registered, the personnummer is issued within a few weeks and activates access to the Swedish welfare system, reduced healthcare fees, and the Swedish identification framework.
Non-EU nationals first obtain a residence permit from the Swedish Migration Agency (Migrationsverket) and are then automatically referred to Skatteverket for population registration and personnummer assignment if the permit is for more than one year. Short-stay permit holders (under one year) may instead receive a coordination number (samordningsnummer) — a temporary identifier used for tax and banking, but not conferring full resident status.
The personnummer is used in every Swedish property transaction. The land registration authority (Lantmateriet) records ownership in the fastighetsregister under the buyer's personnummer. Swedish banks require a personnummer to open an account and issue a mortgage. Without a personnummer, obtaining a Swedish mortgage is effectively impossible — foreign buyers without Swedish residency must typically purchase with cash or via a foreign mortgage.
Swedish tax law requires all residents to file an annual income tax return (inkomstdeklaration) using their personnummer. Rental income from Swedish property is taxable in Sweden under the Income Tax Act (inkomstskattelagen). Both residents and non-residents owning Swedish property must register for Swedish tax purposes, though non-residents use a coordination number rather than a full personnummer.
After submitting your folkbokforing application at Skatteverket, the personnummer is typically assigned within 1-3 weeks. Processing times vary by office and season. You will receive the number by post at your registered Swedish address.
Foreign non-residents can purchase Swedish property without a personnummer, but you will need a coordination number (samordningsnummer) for the Lantmateriet registration and tax purposes. Financing is much harder — Swedish banks require a personnummer for mortgage applications. Most non-resident buyers use cash or foreign financing.
A personnummer is assigned to persons registered as residents in Sweden (folkbokforda). A samordningsnummer is a temporary coordination number for those with a connection to Sweden who are not resident. Both serve as tax identifiers, but the samordningsnummer does not grant access to welfare benefits or Swedish BankID.
