All publishers are required to enter a Personal Identification Number (PIN) to get the eligibity to get the payments from Adsense. PIN detail comes to your mailing address. PINs are necessary to verify and validate the accuracy of your contact information, mailing address. After entering the PIN, Adsense team ensure that you can receive your payments.
You Might have mentioned wrong/invalid payment address
Take a moment to review your payment address, and make updates to your address if necessary.
Adsense PIN might not sent to you
You have to wait for a week after your account balance reached verification threshold for a PIN to be generated and mailed to you.
You will be required to verify your PIN only after your account balance reaches verification threshold (€10 or $10). If you do not see a hold displayed at the top of Overview page, then it means that your account is not on PIN hold yet.
You have not waited for 4 weeks
PINs often take up to 4 weeks to reach you by mail, it may take longer depending on your location. If you have not received your PIN after 4 weeks, you can request a new one. To find the date when you will be able to request a new PIN by logging in to your account and viewing the Account Settings page under the Home tab.
Request for New Adsense PIN
If you haven't received your PIN, or if it has been lost, you can request two more PINs. To make sure it has enough time to reach you, you'll need to wait 3 weeks after your last PIN was mailed before requesting a new one.
