Naar Contacting DUO

Submitting a form

Mijn DUO enables you to arrange a lot of things online. However, you may sometimes have to print, complete, sign and post a hard-copy form – for example if you are abroad or have no Internet connection, or if you prefer the paper format for other reasons. Bear in mind that the response time will be longer than when you make a request or report a change online.

Return adress

Each form has a return address printed in the top right-hand corner. Please use this address to make sure that your request or change report arrives at the right place and you will receive a reply as soon as possible.
