AdSense Pin

 AdSense Pin is a unique Personal Identification Number that is mailed to AdSense publishers who have reached the verification threshold. AdSense Pins are sent via postal mail to the publisher's mailing address provided in their AdSense account.

To verify your AdSense account, you need to reach the verification threshold, which is currently set at $10. Once you have earned $10 or more in your AdSense account, AdSense will automatically send a Pin to the address you provided in your account. It usually takes 2-4 weeks for the Pin to arrive in the mail.

Once you receive the Pin, you will need to enter it in your AdSense account to verify your address. To do this, sign in to your AdSense account, click on the "Gear" icon in the upper right corner, and select "Payments". From there, click on "Manage settings", and then click on "Verify address". You will then be prompted to enter the Pin you received in the mail. After you have entered the Pin, your account will be verified, and you will be able to receive payments.
