You can do the nomination online but you have to submit the form and give a thumbprint at a branch. The way it is explained is truly misleading.

It will only tell you that you need to be present at a branch to complete the process right at the end of the online nomination. You have 30 days to do it before it cancels itself.

It is online on the EPF website when you're adding a new nominee. Once you have finished the nomination, there's an option to download and print then form.
