Is it possible for international users to get a Post Office Box in America, and sign up to YPN with that?
yes but you would still need a U.S. tax # or Social Security #. If you had someone that lived in the states, and used their name, address, numbers on the account, I guess it would be fine...... and they could just send the money to you, if it was a trusted family member etc..... they could just get the account in their name etc, while you did the web work etc......
Actually I believe you would need to have a real address. Since 9/11, and with the Oklahoma bombing in the background ... the use of P.O.Boxes is not allowed for many things that it once was. You cannot open a bank checking account with only a P.O. Box number...you must have a street address that you use and is on your ID. That is also an issue the OP missed as Yahoo mails checks and deposits via EFT but would need to wire to international banks which isnt going to happen quite so soon due to fees and processing time, and I think Yahoo would raise an eyebrow at mailing a check to an overseas address and figure out the person is not a US resident.
You could live in say England or any place....... Have a brother or sister or close, trusted friend sign up for the ypn account, if they lived in the states. You do the net work, etc.... and your friend etc gets the money, either by check or DD, then they just write a check or paypal the funds to you, minus a small fee for their troubles etc.......... That way the person who joined ypn really does live in the states and has a real address, their just sending the funds to you via their own check, or paypal etc. And you do the internet work on your end........
I would just have the friend or family member, tell you what the taxes would be etc, and you could simply have them keep the money needed for that, etc. There are a lot of variables etc...... but I wouldnt consider taxes etc a big thing, like me I may need to keep $20 aside for taxes for the little my ypn etc makes. If you make more, save out more, 25%-30% etc
Below is a quote from the YPN Terms and Conditions take special note to items one and seven. You must be a US registered business.
I don't know why YPN is still not willing to allow over 95% of the world's population in generating revenue for it.
