Hi, I have one Adsense Account but still not active, I already request the PIN two times but not received yet due of bad mail service in my country , so my friend lives in US .it's possible to send the PIN to him instead of me ? by change the payment address and country in my AdSense account? but without effect transferring the amount to me ?
No. There is a reason that they want to send it to YOU at YOUR address. There are two many fraud issues. If you try and do what you want, imagine the red flags that it will raise!
how about if I only going to change the address & country ..without touch the name.. friend can received instead of me
No. Generally if you want to change country, you need to close the account and apply again in the new county - there is no guarantee that the new supplication will be accpeted.
if you did not receive the PIN in your Country and had already requested the 3 replacement PIN's than you may have a option to upload the scan copy of the documents which fulfill your address verification. For Example you can use Driving license, Passport, Utility bills etc.
As much as possible, try not to circumvent their checks and counter checks, you can see a lot of posts complaining about Adsense bans, these come from those who try out the easy way.
