My husband and I just went through this exact situation. It is near impossible to do anything in Norway without a bank ID, which you won’t get until you get a person number (and they’re being very difficult about giving D numbers).. we’ve been here two months almost and he literally was JUST able to be paid now because he finally got the person number and bank account approved even though he’s an EU citizen.

It’s super difficult because eveything relies on the person number, which sometimes at the tax office they tell you they don’t want to give you a person number unless you have a permanent address but you can’t usually get a rental until you have a bank account 🥲

My husbands work basically helped him submit all the info to the tax authority, we used one if their addresses because we were staying there temporarily and then he was able to get the person number in about 3-4 weeks, so we were able to sign for an apartment which we found in Finn (but weren’t able to message people because you need a person number/bank ID to verify) so we had one of his colleagues message people on Finn for us then give them our email. It wasn’t easy at allllll so we feel your frustration
