What is an IP PIN and how do I find it?
An Identity Protection PIN (IP PIN) is a six-digit number the IRS provides to people who have been victims of identity theft, or who opted into the IP PIN program. If the IRS has assigned you an IP PIN you are required to provide it when you e-file your tax return. The IP PIN is meant to provide an extra measure of protection against identity theft.
If you have been the victim of identity theft and the IRS issued you an IP PIN—or if you signed up for the IP PIN program—a new IP PIN would arrive in the mail each year, in what the IRS calls Notice CP01A. The IRS issues a new IP PIN every year—last year's number will not work this year. If you cannot find this year's IP PIN, you can retrieve it online at Retrieve Your IP PIN, by calling 800-908-4490, or by making an in-person appointment at your local IRS Taxpayer Assistance Center.
If you are unable to retrieve the IP PIN, you will need to paper file your tax return.
