NA PS+ Trial in EU

Hi, so basically what i wanna know is how to get the NA PS+ Trial in EU. Ive got an US Account which i opened up with a McDonalds address anywhere in the US. I currentl have a few bucks in my wallet and with the ongoing E3 sale i wanted so save a bit more by starting the 14 day trial. Unfortunately it doesnt let me add my Paypal (bc of the German address) I have a CC but i cant type in my german adress. Is there anything i should be worried about if i use my name, my credit card and just put an US address in there? Is this going to work?
