Samordningsnummer vs Personnummer in Sweden: What HR Needs to Know

Two numbers, two purposes

Sweden uses two types of personal identity numbers for individuals. Understanding which one an international employee will receive — and when — is essential for smooth payroll setup and onboarding.

Personnummer

A personnummer is issued by Skatteverket to anyone registered as a resident in Sweden. To be eligible, the person must intend to live in Sweden for at least one year and hold the legal right to do so. For international employees, this means a work permit of at least 12 months' duration.

The personnummer is the primary identifier in Swedish society: it is used for healthcare, banking, BankID, tax, insurance, libraries, and almost every digital service. Once issued, it does not change.

Samordningsnummer

A samordningsnummer (coordination number) is issued to individuals who have a temporary or limited connection to Sweden but do not qualify for a personnummer. This includes:

• Employees on work permits shorter than 12 months
• Cross-border workers who live outside Sweden
• Individuals awaiting a permit decision who need to be registered for tax purposes in the interim

The samordningsnummer uses the same 10-digit format as a personnummer but includes a modified date of birth digit (+60 added to the day) so it can be distinguished.

What each number unlocks

Bank account (traditional banks)	✓	Sometimes — varies by bank
BankID	✓	✗ — not eligible
Healthcare (full public access)	✓	Limited
Skatteverket tax card (A-skatt)	✓	✓
Pension contributions tracking	✓	Partial

Managing the gap

Most employees on first-time permits will arrive in Sweden without either number. The personnummer takes 1–4 weeks after a Skatteverket appointment; the samordningsnummer can be obtained faster through the employer's tax registration request.

HR actions during the gap period:

• Register the employee for payroll using a temporary tax number while waiting for the official number. Skatteverket allows this for new arrivals.
• Apply for a samordningsnummer immediately via Skatteverket's employer portal — this unblocks payroll reporting within days.
• Book the Skatteverket population registration appointment (for personnummer) on or before the employee's first day.
• Warn the employee that BankID — required for most Swedish digital services — will not be available until the personnummer is issued.

Upgrading from samordningsnummer to personnummer

If an employee initially received a samordningsnummer (because their first permit was short) and later receives a longer permit or permanent residence, they can apply to Skatteverket to be registered in the population register and receive a personnummer. The samordningsnummer is then deactivated. The employee's tax records transfer automatically.
