Have you lost your citizen service number (BSN)?

Have you lost your citizen service number (BSN)?

You can find your BSN in the following documents, for example:

  • your passport
  • your driving licence
  • your identity card
  • the tax return letter that we send you
  • an assessment (for income tax, for example) that we send you

If you have an identity document, but this document does not state your citizen service number, you can request your citizen service number from the Dutch municipality where you are registered. In that case, however, you must show a valid identity document.
