Swedish personal identity number

Students who are staying in Sweden for more than a year must apply for an official Swedish personal identity number. All students who don’t already have a Swedish ID number are assigned a temporary number by the university.

Interim personal identity number (T-number)

If you do not already have a Swedish personal identity number, the university will assign you a T-number so you can register for courses. Exchange students get a T-number from their host department and international students can see their T-number at www.universityadmissions.se on their notification of selection results. 

The T-number can only be used at Stockholm University. If you are studying in Sweden for longer than one year, apply for a Swedish personal identity number.

Swedish personal identity number (Personnummer)

International students who study in Sweden for 12 months or longer must apply for a Swedish personal identity number (“personnummer” in Swedish) at the Swedish Tax Agency (“Skatteverket” in Swedish). The personal identity number is a 4-digit number following your date of birth in the format: YYMMDD-XXXX. Application can be done online or in person at one of the tax agency offices and you must bring a different set of documents, depending on your country of citizenship. You have to visit a tax agency office for identity check.

Coordination number 

If you are staying in Sweden for less than a year and have a need for a personal number, you can get a so called coordination number ("samordningsnummer" in Swedish). Application can be done online or in person at one of the tax agency offices and you must bring a different set of documents, depending on your country of citizenship. You have to visit a tax agency office for identity check.

Applying for a Swedish personal identity number

Visit Skatteverket’s “Moving to Sweden” website for the precise details on how to apply. To ensure that your visit to the service office goes as quickly and as smoothly as possible, you should use the "Move to Sweden" service before your visit. 

Move to Sweden

The required documents to bring to the service office depend on your citizenship or if you move with or move in with a family member. The following is an indication of what documents might be required:

  • Valid passport (or national ID for EU/EEA students)
  • Letter of Acceptance/Notification of Selection (download from www.universityadmissions.se)
  • Your address in Sweden including apartment number
  • For EU/EEA students: Registration Certificate/Proof of Enrolment (download from My studies)
  • For EU/EEA students: the European Health Insurance Card (EHIC)
  • For non-EU/EEA and Swiss students: Information regarding your residence permit: UT card and decision

Additional documentation might be required; consult the Skatteverket website.

Once you are registered at the Swedish Tax Agency it is important that you replace your interim personal identity number (”T-number”) with the new Swedish personal identity number in the University study-administration system, Ladok.

There are two ways of updating your personal number in Ladok:

  • Bring the official paper (“Personbevis”) that you get from Skatteverket or your official Swedish ID-card to Infocenter, or
  • Scan and send a copy of the Personbevis/ID-card as an attached pdf-file directly to: Ladok@su.se. Please also write your current interim personal number (the T-number) in the e-mail.

Reporting a change of address

Students with a Swedish personal identity number have the legal duty to report changes of address within Sweden to the Swedish Tax Agency so that your address is correct in the population register. Reporting your change of address is free of charge and can be done quickly and easily using the Tax Agency's e-service.
