You may need a national registration certificate when you are going to:
- Get an identity card (but not when you apply for an ID card from then Tax Agency)
- Apply to study programmes or schools or for grants
- Apply for Swedish citizenship
- Apply for divorce
- Have a foreign passport, alien’s passport or a similar document.
A national registration certificate shows the information that is registered about you in the Tax Agency's population register database. A national registration certificate is not valid as an identity document.
