All Swedish citizens have a personal civil registration number called personnumme r.
If your stay in Sweden is less than one year you do not require the number. However, if you get a job in Sweden you must have a personnummer , even if you stay less than one year. If you have a residence permit for more than one year, you may apply for a personnummer . This will then entitle you to medical benefits at a reduced cost. You apply for a personal civil registration number at the local tax office, lokala skattekontoret .
