Using PO Box Address for UK Adsense

Hi,

I'm applying to Adsense for Youtube soon. I'm from the UK but I'm currently abroad. Is it possible to use PO Address instead of asking someone to get the pin for me?

Is it okay with Adsense to use an address like that on my account? I'll provide my id for verification, I'm only just worried about the address when it comes to the pin.

Has anyone tried this before successfully?

Thank you

worst that will happen is a turn down if they dont
