Data (citizen service number) not known to ZK

Hello everyone,

I have not been able to log in to Mijnzilverenkruis. I receive a notification that my social security number (BSN) is not known to ZK. 

I never had any problems with DigiD, I am able to log in at all sites. So the problem really isn't with the DigiD. 

Does anyone else have the same problem?


  • Hello Andrei,

    Welcome to the community!

    What a pity that you cannot log in to Mijn Zilveren Kruis with your Digid. Have you recently been insured with the Zilveren Kruis?

    Can you send me a private message with your customer number, date of birth, zip code and house number? I'll see what I can do for you. You can send me a private message by clicking on my name.

    Kind regards,
