An Identity Protection Personal Identification Number, IP-PIN, is a unique, six-digit number assigned to you by the IRS or that you requested.
An IP PIN is valid for one calendar year.
A new IP PIN is generated each year for your individual account.
If the IRS enrolled you into the IP PIN program due to being a confirmed victim of tax-related identity theft, a CP01A Notice is mailed to you with your new IP PIN each year.
If you voluntarily opted in and obtained an IP PIN online, you will need to retrieve your IP PIN online each calendar year as a CP01A Notice will not be mailed.
The IP PIN is generally available in your online account starting in mid-January through mid-November.
An IP PIN must be used when filing any federal tax returns during the year including prior year returns.
