The PIN is generated and sent via standard postal mail once your earnings have reached $50. Once you receive your PIN, you'll need to enter it into the PIN Information Page of your account.
Many concerned publishers’ve asked whether they'll need to complete the PIN process every time, they generate $50 in earnings. Fortunately, the answer is no. You'll only need to enter in a PIN once per account.
If you've reached $50 in earnings and haven't yet entered in your PIN, you'll see a box at the top of your Payment History page labeled 'Required Action'. Click on the 'Please enter your PIN' link to review detailed information about the date your most recent PIN was generated, and when you can request a new PIN, incase if you don’t receive previously sent. Once you've verified your PIN, you should no longer see this language on your Payment History page. For more information, review PIN Guide, and or visit Help Center.
