🌱 First year in NL

I moved to Rotterdam in February. Registered at gemeente, got temporary BSN slip, but full BSN letter still not here. Started new job, employer is asking. What do I do?

Sold on the idea that DigiD handles everything. Then I see the huurcommissie portal wants iDIN. Banks want MijnOverheid tax data. Why is Dutch e-government like 5 different logins?
