Google Adsense: Do I Need A Pin Number For Google Adsense?
Google Adsense will send you a Personal Identification Number (PIN) to the payment address you supplied when you signed up when you accumulate $50.00 in incomes. This is simply another security precaution that Google Adsense has in place to secure their publishers but it is necessary.
Your account payments will be on hold until the PIN is gone into in your account as soon as you’ve been mailed a PIN number. You can still have access to your account and earn money; you simply won’t be paid till the PIN is gone into. Your account will be handicapped if it hasn’t been entered within 1 year.
To enter your PIN after you receive it in the mail, log into your Google Adsense account. You’re now well on your way to getting your very first Google Adsense check.
