Customer number and diary number

What is my customer number at the Finnish Immigration Service?

When you submit your application, you will be given a personal customer number. From that point on, this customer number will be used to identify you. You will have the same customer number for as long as your matter is being processed. The same customer number will also be used if you later have other matters that need to be processed at the Finnish Immigration Service.

Where can I find my customer number?

Your customer number can be found:

  • below your personal details on the certificate of a pending application;
  • in the top right corner of a supplement request or any other letter the Finnish Immigration Service has sent you;
  • in the top right corner of your decision
  • on your residence permit card under “huomautuksia/anmärkningar”.

Please check your customer number before contacting the Finnish Immigration Service. Make sure to include it in all documents that you submit to the Finnish Immigration Service. This will help us handle your matter faster.
