Today i received my AdSense PIN mailer from Google. A month ago i reached the verification threshold for my AdSense account. Google uses PIN as extra layer of security. The PIN is sent to the address associated to the AdSense Account. I got email 20 days before stating that the PIN was sent. I received it only today. The postal department has taken 20 days to deliver from Mountain view, USA to Somanur, TamilNadu, India.
Anyway, iam glad that i will reach my payment threshold of 100 dollars soon and receive cheque from Google Inc.
