If you are a Swedish citizen and your child is born outside of Sweden, you can apply for a Swedish coordination number for the child at the Embassy.
After submitting all needed documents to the Embassy, the Embassy will request a coordination number for your child from the Swedish Tax Authority. The Swedish Tax Authority will issue a coordination number and register your child in the Swedish population register. When this is done you can apply for a Swedish passport for your child.
Please note that children born outside of Sweden and before 1 April 2015 to an unmarried Swedish father and non- Swedish mother did not become Swedish citizens at birth. The Swedish father is therefore required to register Swedish citizenship for the child with the Swedish Migration Agency.
The request for a coordination number may only be done prior to applying for a passport. A passport application must therefore be made as soon as possible after the coordination number has been assigned by the Swedish Tax authority.
