US PSN in Europe

Hi guys, I have an US account but the games I'm going to buy will be from Europe. So, I plan to activate multiplayer and DLC codes from a UK account and set that account as the primary account. Then, by passing my US account, I think I'll be able to play these games with this account. Am I right?

Not sure, i would ask costumer service

@kingslayer0064:

Yes

Thanks but still I have a question. Does PS4 allow online pass system? Someone says PS+ took its place.
