Yes you can. A PIN could get lost in the post for example, so there is a way for peope to request a new PIN.
if u still didn`t receive ur pin, just ask for resend until 3 times? (forgot) till a notice appear say that u cant make any more resend request. Later than that, email adsense support to discuss the alternative way(s) on how to get ur pin. *i got my pin sent to my address almost after 70+ days
i have asked the pin 3 time : then i got the message u cant request another pin due to security reason contact adsense support before ..... i had got my first pin sent 2 day ago . i am more than happy .waiting for my chcek know
